2019 Email Benchmark and Engagement Study
Email statistics from senders and recipients
Introduction
For the last 3 years, Twilio SendGrid has developed and published our Global Email Benchmark Report. In 2019, weâve decided to take a different approach for this report. In addition to global email engagement benchmarks that we see from the sending side of things, weâve also performed a study on the people receiving all those emails.
The 2019 Email Benchmark and Engagement Study is more impactful and useful than ever before. We continued our work with internal data scientists to provide engagement data that we see from more than 80,000 senders, sending over 60 billion emails each month. Global benchmarks that we report on include:Â Â
- Aggregate Open Rate
- Aggregate Click Rate
- Click-to-Open Rate
- Monthly Send Rate
- Inbox providers and devices used in the top 25 countries by email volume
Whatâs inside this yearâs report?
In addition to that, we performed an entirely new study focused on how recipients engage with email. Through this work, weâve been able to answer a number of questions that are valuable to email senders, including:
- How valuable is email to recipients?
- How and why do people interact with marketing emails?
- What compels people to open and click on certain emails over others?
- How much email do recipients want to receive?
- What are recipient frustrations and turn-offs?
Why is this report useful to me?
Like our reports in the past, this report can help senders make improvements to their current email program by learning about how email is being engaged with, where, and on what devices. By reading this report, youâll be able to know a few different things:
- How effective your email program is by comparing your engagement statistics to the global averages.
- What devices and inbox providers are used in the top 25 countries we send email to.
- The key factors that influence why a recipient opens a message and clicks on links inside.
- What frustrates recipients about their inbox and about emails in general.
- How much content and what type of imagery you should include in your next email campaign.
- When recipients would like to tell you their email preferences.
- What makes an email stand out in the inbox.
We coach our customers to listen to their recipients more than anything. Knowing that your industryâs average open rate is 5% doesn't mean much if the average open rate for your contact list is 15%. As a result, weâve changed the focus of this report from previous reports, and are instead providing data on how recipients engage with the email they receive.

Methodology and Data Collection for Global Email Benchmarks
This benchmark report contains metrics from email sent through Twilio SendGrid. These same metrics and methods have been applied in previous years and will be applied to future years and subsequent reports to consistently compare changes in email statistics and devices in different email regions.
The data for this analysis came from approximately 100 million recipient engagements from over 100,000 different senders. All data is anonymized and only analyzed/reported in the aggregate.Â
This report is primarily representative of business to customer (B2C) email for the countries in which we have significant market penetration.Â
This study may not be representative of personal email.
Twilio SendGrid collects metadata on all events in the email process, including delivery to the inbox provider, opening of email, and any clicks on links within emails. We use metadata to provide services and information to our customers and to improve our service as a whole.Â
For the benefit of our customers and all email senders, weâve summarized this data in the aggregate segmented by:
- Location of the recipient
- Device and inbox used by the recipient
Hereâs how we analyzed and segmented our data:
Associating email with geography – IP addresses collected from opens and clicks were geolocated using up-to-date databases.
Detecting recipient devices – SendGrid uses user agent parsing libraries to automatically infer and categorize the hardware and software being used by a recipient when they open or click an email.
Determining recipient inbox provider – Recipient inboxes are inferred from the domain in the email address and from the IP address associated with the domain.

Global Email Engagement Benchmarks for 2019

Global Email Engagement Benchmarks for 2019
The global email benchmarks for 2019 are quite a bit different from what we saw in 2018, and they reverse a couple trends that were developing:
This data reiterates a lot of what weâve coached senders on for years: as the number of messages to recipient inboxes increases, the engagement with those messages drops.
- Aggregate Open Rate dropped from 18% to 14.5%
- Aggregate Click Rate dropped from 2% to 1.6%
- Click-to-Open Rate dropped from 11.1% to 10.9%
- Average Monthly Send Rate increased from a median 7 emails per month to 8.3
As we can see, the average number of messages sent to recipients increased to 8.3 in 2019. This corresponds with the drops in Aggregate Open Rate, Aggregate Click Rate, and Click-to-Open Rate.  Â
An interesting note is that the Click-to-Open Rate continued to drop for the fourth year in a row. We believe that this demonstrates that recipients are increasingly selective about what messages theyâll interact with. While many recipients will open their emails, theyâre not going to click on just any link within an email.Â
The drop in Click-to-Open rate could also signal that messages are too generalized. This is where larger, more sophisticated senders have the upper hand. Senders who are able to add more personalization have a better chance at getting those messages opened.
People will check email on almost any device they own. Whether they’re at work on a laptop, at home on their phone, or traveling with a tablet, people check their messages many times a day. It’s more important than ever before that your messages are able to load properly across all inbox providers, browsers, and devices.Â
- In 2019, the number of clicks on mobile vs. non-mobile increased from 55.6% to 61.9% on mobile devices. This could be attributed to changes in industry volumes. For instance, there are a lot of political emails being sent right now, more than in non-election years. People could be interacting with this increased political sending on their devices rather than their computers, causing an uptick in mobile usage.
- This may seem counterintuitive, but recipients in our study said they not only switch between mobile and non-mobile devices, they even prefer to look at some messages on desktop over mobile because itâs easier to click links and search for things with the keyboard.
This table shows the percentage of recipients that have that type of inbox provider in each country, not the volume of email each inbox provider receives in each country. Each recipient gets counted once per email address. If a person has one account, regardless of how many messages go to that account, theyâre only counted once.
- Gmail continues to be the inbox used by most people across most countries, with Yahoo and Hotmail generally in second or third place. Each of these inbox providers require properly authenticated email in order for it to be delivered correctly. Make sure your IP address and domain are authenticated to ensure your email is being placed where it should be.
- Outside of the top 3 inbox providers, senders should be aware of the smaller providers in countries they send email to as these could represent a significant number of customers or users.Â
- Usage of the top three inbox providers dropped slightly in the United States, which indicates that other, smaller providers are gaining some usage.
- While Gmail has the largest share of email addresses in Germany, it still only accounts for 20.8% of all addresses in that country. This is a situation where senders should be aware of the inbox providers their recipients use. If you have a lot of German recipients on your list, you may be sending email to 6 different inbox providers, so youâll want to make sure your account is authenticated and your messages load correctly across all of them. Â
- Other countries, like Russia, have Gmail as well as 2 other inbox providers (mail.ru and yandex.ru) that we donât see in any other countries. This could be attributed to Russia using the Cyrillic alphabet as opposed to the Latin alphabet used in most other countries.
Twilio SendGrid uses user agent parsing libraries to automatically infer and categorize the hardware and software being used by a recipient when they open or click an email. In the table above, a âgenericâ device is typically something that is running on the Android operating system, but has masked the type of device used. These mobile devices could be a combination of any number of device manufacturers like Huawei, LG, Google, OnePlus, Motorola, etc. Â
- In general, senders should make sure their messages load properly on all Samsung, Apple, and other Android devices. These are the operating systems most commonly used across the world.
- Appleâs share of devices actually dropped in a handful of countries, including India, Indonesia, and Argentina. If youâre sending international email to these locations, make sure your mail is loading well on Android devices.Â
Consider looking at your click rate at the device level. If you see that there's a strong click rate on Android devices, but there's a drop-off when it comes to iPads, it could point to emails not working correctly on those devices and/or operating system. We've met with some customers who haven't re-worked their emails in years, and as a result, they don't work with the updated software.

Recipient Email Engagement Data and Insights
While itâs helpful to know what the email engagement benchmarks are as a sender, thereâs an equally important aspect of the email communication channel: the recipient. This year, we set out to answer some fundamental questions around recipient engagement:
- What emails are recipients interested in engaging with?
- What elements impact a recipientâs choice to open and click on an email?
- When do recipients become frustrated with the number of emails they receive?
- Why do recipients ultimately decide to unsubscribe?
- What email elements stand out to recipients most?
- What makes an email memorable to recipients?
By listening to recipients and learning about what theyâd like to see in their inboxes, senders can craft and send more valuable emails that have a better chance of being opened and engaged with.
Review your metrics to improve recipient engagement!
If your engagement has started to plateau or even decline, it might be time to take a more advanced approach to how you manage and measure your email program.

Methodology and Data Collection for Recipient Engagement
The recipient engagement portion of this report was conducted with a qualitative ethnographic study, and a quantitative online survey, both of which were conducted in the United States (U.S.) and the United Kingdom (U.K.).Â
Qualitative email insights
To gain qualitative email insights and to track daily email usage habits, we interviewed 40 total study participants, with 20 in the U.S. and 20 in the U.K. The sample was segmented by age group, divided into the following age brackets:
- Gen Z: 18-24, 5 in the U.S. and 5 in the U.K
- Millennials: 25-35, 5 in the U.S. and 5 in the U.K
- Gen X: 36-50, 5 in the U.S. and 5 in the U.K
- Baby Boomers: 51-60, 5 in the U.S. and 5 in the U.K
The participants used a mobile ethnography app to answer email-related questions throughout the day. They were sent 3-5 questions a day for 5 days. Using video responses (approximately 1-2 mins in length), along with screenshots and phone-screen recordings, participants shared with us their daily email habits. This gave us more detailed feedback than an interview alone, as it allowed us to observe and track over time.
At the conclusion of the week, we debriefed with participants in an in-depth video interview lasting 30-45 minutes.
Quantitative online survey
Once we completed the mobile ethnographic study, we wanted to quantify those qualitative themes, and see if these findings applied across a statistically valid sample size. We developed an online study that was conducted in the U.S. and the U.K. with 800 participants from each. Those participants were then divided up amongst the 4 different age categories so that 200 participants in each category completed the survey.

Email is Essential

Email is Essential
Throughout all our research, one thing was reiterated over and over again: email is not only important, itâs an essential channel for communication between recipients and companies. Most of our study participants say the emails they receive from businesses are valued because they provide important information that they want.
Emails help people track what theyâve bought online, when orders will ship, alert them to sales and discounts, remind them what bills they have to pay, and provide updates about the brands they love. Email has become a part of their morning rituals and routines. Some even say theyâre addicted to their email.
Across the U.S. and the U.K., and across all age groups, 84% of participants check their email at least once a day, with the majority of people checking messages numerous times throughout the day.
Email is ingrained in everyday life for almost everyone. We found that across all study participants, email was the most essential communication channel. 97% of study participants consider email to be essential, followed by text messages, and then social media.
I check my emails in the morning and while commuting to work on public transportation. I check emails throughout the day to see if there's anything that requires an immediate response. In the evening, I will go through emails using my laptop as it's quicker to type with a keyboard.

Email Frequency
Chapter 7
↓
Email Frequency
We saw in Twilio SendGridâs email benchmarks that the average number of emails sent each month to recipients increased from 7 in 2018 to 8.3 in 2019. We wanted to learn more about how comfortable recipients are with the amount of email they receive and the frequency of messages they get from companies theyâre interested in.
Based on these results and our qualitative study, recipients are more forgiving when emails are sent by one of their favorite retailers. Theyâre even open to the idea of receiving daily messages, just as long as they want the product or service offered, or theyâre particularly interested in the sender or brand.Â
For the most part though, receiving too many messages in a short span of time often results in a quick deletion, and can trigger an unsubscribe with repeat offenders.
Most of our study participants said they would only like to receive promotional emails from retailers once a week, and just a few say they are fine with daily emails. A few others are open to seeing emails outside of this frequency if a limited time offer is involved.
Email senders should identify which recipients want to receive email once a day, and which want to receive email once a week. Once you have an idea of who wants to receive a lot of email and who doesn't, you should think about your offers. Do your offers necessitate a once per day email? Are you sending different offers each day, or are you sending the same thing over and over again?

Elements of a Good, Successful Email

Elements of a Good, Successful Email
If you were asked right now, what were the last 10 emails you opened, would you be able to name them? Chances are, you might be able to describe a couple, but not much more than that. Thereâs more email being sent today than at any other time in history, which is why making an email memorable and interesting to recipients is so important.Â
We wanted to learn more about what makes a good, successful email stand out from the rest. So we asked our study participants to provide us with their insights and opinions around a number of different email elements, including:
- Personalization
- Images, Videos, and GIFs
- Content
- Responsiveness
Below, weâll dive into each of these topics with the relevant quantitative analysis and any relatable insights from our mobile ethnography.
Personalization
These days, some level of personalization is expected in essentially every email that comes to the inbox. Whether youâre including a recipientâs name, including specific information exclusively for them, or just sending them product offers, recipients expect senders to know something about them.
Across both the U.S. and the U.K., 26% of study participants said that personalization is something that would make an email very memorable. Another 38% of participants said that personalization would make the email somewhat memorable.
When we compare the U.S. and the U.K. next to each other, we see that responses were very similar. 29% of those in the U.S. said that personalization was something that made an email very memorable, compared to 22% in the U.K.
In interviews and in our mobile ethnography, many recipients suggested they would be more inclined to read emails they receive (and not delete or unsubscribe from them) if they were more personalized or relevant. Recipients like seeing emails that include their name because it suggests the content is exclusively for them.
Images, videos, and GIFs
Imagery is an essential element of just about every email. Whether youâre including pictures of your products, a background image in your brandâs colors, a GIF highlighting new features, or a video walkthrough of your software, images help you convey your message. We wanted to learn what the right number of images is for an email from the recipient perspective.
Overall, recipients want images in their emails, but they only want a few at most. The vast majority of participants, 85% across the U.S. and the U.K., indicated theyâd like 1 to 3 images in their emails at most.
Through our interviews and mobile ethnography, our participants told us a few additional things about what they think about images in email:
- Images add more context to the messages they receive.
- Images and video content should load quickly and display properly, especially on mobile devices, otherwise they detract from the message.
- Recipients are especially fond of images that help illustrate products and services, like clothes or travel destinations, and videos that demonstrate how a product might be used or assembled.
- Some recipients are open to emails that are more interactive and use more images/graphics. Thereâs also some interest in seeing more video, which a few felt would be quite novel.
- Most recipients expect to see less text when images are present, or a better balance of text and graphics.
- Most recipients do not want emails to have too many images, which can make them look busy.
To learn more about their opinion of GIFs and video in email, we asked them if they liked GIFs and video in email from companies advertising products or services.Â
Across all age groups and locations, the majority of people do not like GIFs or videos in their emails. The most tolerant age group across the two countries were Millennials, with 51% saying they did not like GIFs and video. The most intolerant of the age groups were Baby Boomers, with 76% saying they didnât like GIFs and video.
When we looked at the data more granularly, to see the age groups within countries, there were some other interesting takeaways.
When age groups are split by country, we see that there are some where the majority of participants actually like GIFs and video. Millennials and Gen Z participants in the U.S. both indicated they like these moving images with 56% responding with âyes.âÂ
Another interesting note is that U.S. participants were much more tolerant of GIFs and videos than those in the U.K.. The group that indicated they absolutely do not like GIFs and videos are Baby Boomers in the U.K.. Some qualitative insights we got about GIFs and video include:
- Images can be animated, but should not endlessly strobe or blink.
- A few older participants were a little leery about receiving video or clicking links to see video because they could lead to viruses.
Content
The content within an email is just as important as every other email element. An email with a great subject line and no content doesnât provide the recipient with any useful information. Email content should be descriptive and provide your recipients with information about the offer youâre sending, or tell them why they should engage with the links in the message. Like images, having too little content or too much are both turn-offs for recipients:

Much like their criticism of subject lines, study participants really dislike emails that are too long and wordy, and not very concise. However, an email with no content, and just images is also not interesting to recipients. The general consensus is that an email should definitely have some content, just not too much. Other qualitative takeaways include:
- Some emails can be difficult to read if they are too text-heavy.Â
- Recipients are turned off when emails have spelling errors, which suggests a lack of professionalism.
- Some prefer shorter emails, which only require a quick scroll or two to read, and want these every other day.Â
- Others say they prefer longer, more detailed emails, particularly if they are interesting and relevant, but would only want to see these once a week or less.
- Recipients dislike it when the content of an email doesnât live up to the subject line that enticed them to open.Â
- A few also dislike emails that take a hard sell approach, seem too pushy, or try to guilt them into buying something.
Responsiveness
Email recipients expect an email to load properly on the device theyâre using to view it. Whether itâs a phone, tablet, or computer, your email should appear correctly so that they donât have to zoom in or scroll awkwardly in order to read it.
Of all participants, 66% said that it is essential for an email to load properly on all devices. In the U.S., this percentage grows to 70% of participants, and drops to 63% among U.K. participants.Â
Study participants specifically told us that they would like it if senders formatted their emails so that they display properly on different devices, and take into account the narrowness of phones versus the wider displays they have on their computers and laptops.
We also wanted to learn more about how often email recipients open an email on one device, and then switch to another.
A quarter of respondents said they âneverâ switch between their phone and computer, while about 60% said they seldom or sometimes switch between the two. Recipients may not switch between devices a lot, but when they do, the email should load properly.Â
We saw in our qualitative study that recipients may not go from one to the other very often, but sometimes it makes sense to switch to a computer. If recipients see an offer or promotion that looks particularly enticing on their phone, some will switch to their computer to take advantage of it and complete their transaction.

Get your email program in tip-top shape for 2020 with our updated best practice guide.
Based on our study, the group of people who said they switch between devices the most were Gen X participants in both the U.S. and the U.K. 11% said they frequently switch between devices, and 43% of Gen Z recipients in the U.K. said they sometimes switch between the two.Â
Whatâs interesting here is that it is the younger age groups that say theyâre switching from their phone to the computer and vice versa. 35% of Baby Boomers said they never switch between the two, while only 20% of Gen Z, 22% of Millennials, and 28% of Gen X participants said they never switch. Millennials had the highest percentage of sometimes switching at 38%.
Responsive design doesn't just mean ensuring your email loads and displays properly across devices, it means ensuring your calls-to-action are relevant across platforms. If you're sending an email that has a link that opens an app on a phone, the experience may be broken if the recipient is clicking that link on their desktop. The link on the desktop should go to a landing page that describes the feature in more detail, encouraging the recipients to go back to their phone and engage with the app.

Factors That Influence Opening an Email
Chapter 9

Factors That Influence Opening an Email
We saw in Twilio SendGrid’s email engagement benchmarks that the aggregate open rate for email dropped this year to 14.5% while the number of emails sent by all senders increased in frequency. For recipients, this means they’re getting a lot of email in their inboxes, and they have to decide what they want to open. Â
We asked participants in both the mobile ethnography and the online survey to rank the elements of an email that impacted their decision to open the message:
- Sender
- Subject line
- Offer/promotion
- Content
- Time of day
Overall, the most important element of an email that impacts a recipient’s choice of whether they should open it or not, is the sender. Recipients typically check who an email is coming from before choosing to read the subject line or determining whatâs inside the email itself.
SenderÂ
The sender instantly conveys where an email is coming from. Emails are more likely to be opened when recipients have some relationship with that company, or are expecting to receive emails from these trusted, subscribed-to sources.
The chart above shows that across all ages in the survey, more than half of respondents said that the sender would strongly influence their decision to open an email. That influence is strongest with the Baby Boomer group, with 61% saying that the sender is a strong influence. The Gen X group had the lowest number of people saying the sender is a strong influence, at only 45%.
For some recipients, the sender alone is all the information they need to open an email, especially when they are very fond of a particular brand. In general, when recipients open their inbox, the sender is the first thing they look at, and if they donât feel like seeing that companyâs product or service, they scroll right past.
Another interesting thing is that the sender remains the most influential factor for opening an email across the U.S. and U.K. as well. Below are charts comparing how the sender influenced study participants in the U.S. and the U.K. The results are very similar:
The bottom line is that your emails are much more likely to be opened if the recipient knows who you are and is interested in your company or brand. Messages getting sent to recipients who are unaware of you, or who have never interacted with you in the past, are going to be ignored.
Recently, political senders have been employing the use of âfriendly fromâ addresses in their emails. Friendly from addresses are the visible part of an email address displayed in email clients as the person/entity sending the message. For instance, the email address might include a familiar name like âBritney.Spearsâ and @yourdomain.com. This tactic may seem like a good way to stand out in the inbox, but in reality, if it confuses recipients, it may be ignored or even flagged as spam.
Subject line
Recipients want to have a clear idea of what an email is all about before they even open it, which is where subject lines come in. However, recipients didnât indicate that subject lines have more influence over their decision to open than who the email is coming from:
Unlike with the sender of an email, participants were a little more unsure of how influential an emailâs subject line is on their decision. Most study participants were split between a subject line strongly influencing the decision, or just somewhat influencing the decision. This split is reflected across the U.S. and U.K., too:
Subject lines should be clear and concise, and descriptive enough so they are not vague and ambiguous. Participants said they liked subject lines that were interesting and informative, have a hook, or present information in a fun and catchy way because theyâre more compelling.
ContentÂ
The content of an email is an extension of the subject line and sender. Typically, the purpose of the subject line is to describe the content of the email itself and encourage the recipient to open the message, but the best subject line ever written wonât help if the content of the message isnât relevant or interesting. One really doesnât work without the other.
Whatâs inside the message is the second most influential factor when it comes to the open decision, and this data reflects what we heard from our mobile ethnography participants:
- Relevant content is valued, but content must also echo the subject lineârecipients don’t want to be disappointed, or feel their time was wasted after opening an email.Â
- Some recipients say content is mootâthey won’t read it if they don’t get past the sender or subject line.
For senders, this means that the sender, subject line, and content are all working together pretty closely. A recipient wants a clear descriptive subject line that tells them about the value inside the email, from a sender they recognize and like. This influence was reflected across both countries as well, with the U.S. ranking content as having slightly more influence than the U.K.
Offers and promotionsÂ
For many ecommerce businesses, the subject line is really just a way to inform recipients about their current offers and promotions. Youâll notice plenty of these in your inbox right now:
- Save $50 by Ordering Now!
- Reminder: 50% off your delivery fee
- Take an extra $15 off your next order
A lot of study participants will scan their inbox for large discounts, verify the sender, and then choose to open the email itself.
Interestingly, the influence of the offer or promotion was ranked differently between the U.S. and the U.K.:
U.S. participants seem to indicate that the offer or promotion is more influential to them than their peers across the pond. In the United Kingdom, participants leaned more toward offers and promotions having âsomewhatâ of an influence on their choice.Â
Our qualitative study participants told us that deep discounts, sales, and promotions often catch their eye, particularly when these are touted in the subject line, but what’s sold must align with what they need. Several recipients said they wouldnât bother opening an email unless they received at least 40% off.
Time of day received
As we showed previously, the vast majority of email recipients are checking their email multiple times each day. This means that the time of day that they receive an email isnât as important as it may have been in the past. While you want to make sure your email reaches people, and stays toward the top of the inbox, most recipients are going to check their messages to see if theyâve received anything recently.
Of all the email factors, time of day was ranked as having the least influence on the decision to open an email. On average, only 13% of all participants indicated that time of day had a strong influence on their decision. This was also reflected across both countries:
During our mobile ethnography study, our participants echoed these quantitative results. Participants said that time is of little importance, as they check email throughout the day, and they will open a good email regardless of when it is received. The only time they said that time of day was important was when the message was time sensitive.

Factors That Influence Clicking Links Within Emails
Chapter 10

Factors That Influence Clicking Links Within Emails
As you continue along the recipientâs engagement journey, after they choose to open an email, theyâre brought to another decision: what should I click on in this email? Over the last 4 years, the average click-to-open rate has dropped from 13.6% in 2016 to 10.9% in 2019. This suggests that recipients are opening messages quite a bit, but theyâve become more selective on the offers theyâll actually click on within messages.
In order to learn more about the decision to click on links within emails, we asked study participants to rank how influential each of the following factors would be in prompting them to click on a link:
- Critical information (shipping notification, receipt, password link, etc.)
- Relevant products
- Offer/discount
- Link placement
- Color of link
- Link copy
- Brand of sender
- Content of email
Unlike the decision to open an email, there isnât one factor that clearly influences the decision to click links more than others. Across all study participants, the email factors with the highest percentages of respondents saying they would strongly influence their decision, include:Â
- Offers/discount
- Critical information (shipping notification, receipt, password link, etc.)
- Content of email
- Relevant products
- Brand of sender
These factors also had the lowest percentages of recipients saying they wouldnât influence their decision very much or at all. The other email factors (link color, link copy, and link placement) donât seem to have nearly as much influence on the choice to click on an email. When we looked at how the U.S. and the U.K. ranked these factors, some interesting differences arose:
Unlike the U.S., participants in the U.K. ranked factors as having a strong influence much less than the participants in the U.S. For instance, when it comes to critical information in emails, only 29% of U.K. participants said that factor had a strong influence, as opposed to 43% of U.S. participants. Â

Join our team of email experts in our latest webinar as they walk you through the step-by-step process of designing breathtaking emails.
Offer/discount
The offer/discount within an email had the highest percentage of people who considered it to have a âstrong influenceâ on their decision to click on a link at 39%.Â
These rankings reflect what we learned earlier about why participants choose to open an email. If an email is touting a deep discount in the subject line, the recipient may choose to open the message itself, and in order to capitalize on the discount, theyâll have to click on a link to the site.Â
Other emails may be very informative and get opened, but they donât necessarily require a click on a link. A newsletter or welcome email is a good example of an email where a recipient might open the message, but not necessarily click on any of the links.Â
Content of email
While some promotional emails are very straightforward, others require some content in order to drive value and influence recipients to take the next step by clicking on a link. The content of an email had the second most rankings of âstrong influenceâ at 37%.
This is good news to any email marketer out there spending time crafting good, informative email content because it shows people are actually reading and evaluating what youâre sending them. As a sender, you should try to send your recipients messages that provide value. Not every email campaign can be a 50% off promotion.
Critical information
Critical information in an email can be many different things, but generally, itâs information thatâs included in transactional emails:
- Shipping notifications
- Receipts
- Purchase confirmations
- Password reset links
We looked at these types of emails and what they provide as different from the more general âcontentâ email factor.
Study participants were split on how much of an influence critical information has on their decision to click links with 36% saying it would have a strong influence, and 34% saying it would have somewhat of an influence. Millennials had the highest percentage of participants saying it would have a strong influence at 41%.
For something like a password reset email, the whole purpose of the message is to provide you with the link inside the email. For others, like a purchase confirmation, a recipient will most likely open and look at the message, but they probably wonât click on anything inside, unless something looks wrong.
Relevant products
Recipients view emails from brands they like, with information about products they want, to be more than just promotional emails. Study participants told us emails that are informative and functional get attention and are useful. They believe emails about new product announcements and upcoming sales, especially when they include coupons, fall into this category.
Fewer participants ranked relevant products as having a strong influence at 32%, and 41% said it had somewhat of an influence.Â
Our qualitative study participants told us that once they choose to open an email, if itâs from a retailer or other ecommerce site, they want to see relevant products. However, weâve already seen that the Click-to-Open Rate has been dropping for the last 3 years, which means, they may want to see these items, but theyâre going to be even more selective in clicking on things. Recipients want:
- Emails to reflect the buying history they have with the vendors and retailers they subscribe to.Â
- To receive offers and discounts for items similar to the ones they have bought in the past, and not for items they might have only been browsing on a company’s website.
- News about the products they currently own, and whether upgrades or new versions are available.
- Curated recommendations based on their previous activity. Recipients expect retailers to anticipate their needs and suggest goods they should be buying.
Rather than attempting to include all your value props and story in an email, senders should focus on driving recipients back to their website. Once a recipient has come to your website, you have a lot more control over their experience, the offers and products they see, and how they finally purchase something.
Brand of sender
Much like how the sender strongly influences the decision to open an email, the brand of the sender also has an influence on the recipientsâ choice to click links within an email. Many recipients will see whoâs sent them an email, open the message, and even if they donât see anything in the message they like, theyâll click through to the site because they have an affinity for that brand and their products.
In addition to being one of the influencing factors in deciding to click email links, the brand of the sender can also cause frustration. Recipients particularly dislike when these emails do not come from a recognized sender. When that occurs, the emails seem suspicious and dishonest. This makes them feel like they are getting spam.
As an email sender, make sure youâre following address collection best practices so that your messages are only being sent to recipients who are familiar with your brand, and want to receive those messages.
Link placement, link copy, and color of link
Many senders spend a lot of energy thinking about how they can make the links in their email stand out, and weâve all heard stories about changing the color of a button in order to drive more clicks. Unfortunately, the color, placement, and even the text of the link are all factors that recipients say have the least amount of influence.
Obviously, links are critical for any email, but rather than focusing on the perfect color of a button or call to action, senders should focus more on providing value in their messages, and having a call to action that stands out, that recipients can engage with. Â

What Drives Email Frustrations and Unsubscribes?
While itâs nice to know what recipients prefer or enjoy about email messages, itâs equally important to understand what frustrates recipients about the email experience. Identifying these frustrations can help email senders improve their emails and sending habits so that recipients are more likely to engage with their emails, and less likely to unsubscribe.Â
Below, we look at a few different parts of the recipientsâ email experience. We asked our study participants 3 questions:
- What do you find frustrating about your inbox?
- What are the top turn-off factors in email?
- What frequency of emails would prompt you to unsubscribe from an email distribution list from a company with products that interest you?
Inbox Frustrations
Just about everyone has some type of email inbox. In 2018, The Radicati Group, Inc. estimated there were about 3.8 billion email users around the world, and that number is expected to grow to more than 4.2 billion by 2022.Â
Whether theyâre checking it multiple times a day, or just once every day or two, they have a repository of email messages. The email experience can be frustrating for recipients, especially with the volume of email each person is receiving. We asked study participants to rank the following frustrations about the inbox for us:
- Number of messages
- Unknown senders
- SPAM filters not accurate
- Hard to search for emails
- Too hard to unsubscribe from emails from companies
- Emails that arenât designed for mobile devices and donât load properly
- Difficult to organize for relevant emails from senders I want to receive email from
- Other (Fill in)
Across all age groups, the three factors that recipients found to be most frustrating were:
- Number of messages
- Unknown senders
- SPAM filters not accurate
This means that recipients are tired of getting so many emails in their inbox, especially from unknown senders. âSpam filters not accurateâ indicates that recipients are frustrated when wanted email is sent to SPAM incorrectly. These three frustrations remain in the top when we look at age groups in both countries.
One interesting difference between the two countries is that unknown senders seem to be what frustrates people the most across all age groups in the U.K. at 56%. In the U.S., the three top frustrations are much closer. As a sender, this reiterates what we tell our customers: make sure youâre only sending email to people who are familiar with your brand and want to receive your messages.

The top turn-off factors in email
Now that we know whatâs frustrating recipients about their inboxes in general, we decided to dive a little deeper and learn about what frustrates them about the messages they receive and open. We asked study participants to choose their top three email turnoffs from the following list:
- Irrelevance
- Emojis
- Grammatical/spelling errors
- Unknown brand or company
- Un-personalized content
- Poorly Designed graphics/text layout
By far, the three biggest turn-offs for our study participants were:
- Irrelevance
- Unknown brand or company
- Grammatical/spelling errors
Email recipients dislike irrelevant messages. For instance, sending an email about dog chew toys to cat owners will likely frustrate the recipient far more than drive engagement. Second to irrelevance is email from unknown brands or companies. Mail from unknown senders isnât likely to be opened, and it adds to the rest of the messages in inboxes.Â
Lastly, grammar/spelling errors in emails is frustrating to recipients because it makes the message look suspect, and makes the brand look unprofessional. Make sure youâre always double-checking your messages so theyâre typo-free!
Looking at differences between age groups and locations, Baby Boomers appear to be the most intolerant of irrelevant emails, with 84% in both countries ranking that as the biggest turn-off.
Email has been around for so long now, and recipients are so familiar with it, that they know what email should and should not look like. By pushing the boundaries and incorporating any and all new graphic design trends, you could be turning your recipients off instead of intriguing them.
Emojis: đ„° or đ«?
Emojis didnât rank very high in our quantitative survey, which could mean they still turn people off, just not as much as the top three. Our qualitative study participants, however, definitely had some opinions about them.Â
Of all the age groups, Gen X and Baby Boomers dislike seeing emojis the most, and suggest theyâre annoying. They feel emojis are unprofessional, look childish, and often cheapen an email offering. This is especially true if the sender is a financial institution or one where trust is a cornerstone of a business relationship.
GenZ and Millennials tend to be more split when it comes to emojis. While several echo what the older generations say, some feel emojis do fit with certain brands that are fun and playful.Â
The bottom line is, as a sender, you should have a good read on your recipients and customers. If your customers tend to be a bit older, it may be worth skipping emojis in your subject lines. If youâre a younger company with a young client base, include them, but donât go overboard.
How to Remedy a High Email Unsubscribe Rate
While we donât have a magic ball to tell you why youâre getting too many unsubscribes, here are some questions to ask yourself as you investigate.
What frequency of emails would prompt an unsubscribe
As we saw above in our global benchmarks, the average number of messages sent each month increased in 2019 from 7 to 8.3 messages per month. This means that on average, email senders are messaging their recipients more than twice each week.Â
We wanted to learn if an increase in sending frequency would cause recipients to unsubscribe from an email list.
Whatâs interesting to note, 54% of all participants say that if a company were to increase their sending frequency to an email every day, it would be a significant factor in their choice to unsubscribe from that email list.Â
Receiving too many emails from the same sender over the course of a week is one of the biggest pet peeves reported in our recipient ethnography study. Their annoyance is compounded when a company bombards their inbox multiple times a day, or the offers they receive are all very similar, and the sender does not seem to have anything new to say.
Have a closer relationship with your recipients and know what they've bought in the past. If you have someone that bought a product they won't need to replace for a year or two, continuing to send them offers on that same product isn't going to drive another purchase. Think about other products they may want or need.
While they say they appreciate emails that might benefit them in some way, such as those that promote a sales event or offer a discount for an online purchase, several say promotional emails can also be quite annoying.
Frequency was also important to several participants who were turned off when companies send too many emails in a short span of time, or when these emails look too similar and feel too repetitive.
Email preferences
In general, the best way for an email sender to get recipients to open and engage with emails is to send them content and offers they want to receive. Weâve already seen that irrelevance is one of the most frustrating things about emails, so ensuring those emails are relevant to recipients should be at the top of the list for email senders to do.
One of the easiest ways to accomplish this is to simply ask recipients what type of email theyâd like to receive. Oftentimes, companies only provide an email preference center when a recipient has decided to unsubscribe from their messages. Unfortunately, this isnât when recipients want to give you their email preferences.
Overall, 60% of participants would prefer to tell companies exactly what kinds of email theyâre interested in right when they provide their email address for the first time. An additional 24% of respondents said theyâd be interested in a survey emailed to them soon after providing their address.Â
When we look at how these responses compare country to country, there are a couple of interesting things observed:
While the vast majority of participants still want to provide their email preferences when they first submit their email address, 13% of Baby Boomers across both countries said that they donât want to share their email preferences.
For the most part, companies are eager to gain new email subscribers, but theyâre not as interested in letting the subscriber determine what email theyâll receive. The email sender benefits if they include those sending preferences at the beginning of their relationship with the recipient.
When we interviewed participants for qualitative insights around this, we gained even more insights:
- Recipients wish there were more ways to control the frequency and types of emails they receive.Â
- Some recipients would like companies to contact them shortly after they have subscribed to gauge their interest in current email offerings, learn how these can be improved, or help them adjust the frequency of what they receive.
- Relevant emails are interesting emails, and recipients engage. As a result, recipients would even be interested in providing more than just email preferences, indicating theyâd be happy to provide likes and dislikes, sizes of clothing they wear, hobbies/interests, and other details to ensure the emails they receive feel more personal.
- A few participants felt such a move would convey a company really cares about their business relationship and the dialogue they have with them as a trusted sender.
When you don't collect email preferences at signup, you create more work for yourself by trying to figure out how much email is right for your recipients. In general, once a recipient has made the decision to unsubscribe, they're not interested in updating their preferences at that time.

Key Differences Between Age Groups
You might think that older email recipients would have stronger, or different opinions than younger email recipients, but in general, thatâs not what our research showed. The differences that stood out include:
- 44% of Millennials want daily emails about products theyâre interested in, but only 31% of Baby Boomers want daily emails. 25% of Baby Boomers would prefer getting emails just once every two weeks.Â
- 61% of Baby Boomers said that the sender of an email would strongly influence their decision to open the email as opposed to only 45% of Gen X participants.Â
- 27% of Gen Z and Millennial participants said that the Brand of the email would make it very memorable while only 15% of Baby Boomers said Brand would make an email memorable.Â
- The top-ranked frustration about the inbox for Baby Boomers was Unknown Senders, at 65%. The top-ranked frustration for Millenials was Spam Filters Not Accurate.Â
- Younger age groups indicated they would switch between devices more often than older age groups. 38% of Millennials said they sometimes switch back and forth, but only 27% of Baby Boomers sometimes switch.Â
- The biggest difference between age groups comes in their opinions of GIFs and videos. 76% of Baby Boomers do not want GIFs or videos in their emails. 52% of Millennials donât want GIFs or videos.

Key Differences Between the U.S. and the U.K.
Like the different age groups, there werenât many differences between email recipients in the U.S. and those in the U.K. The areas we did see the largest differences include:
- 43% of U.S. recipients would actually like daily emails about the products theyâre interested in, as opposed to just 31% of U.K. recipients.Â
- Highest Interest – 49% of Millennials in the U.S. would be interested in daily emails.
- Lowest Interest – Only 24% of Baby Boomers in the U.K. wants daily emails.Â
- The U.K. has a clear hierarchy when it comes to email factors that influence their decision to open an email: Sender, Content, Subject Line, Offer/Promotion, Time of Day
- Email factors that influence the decision to open an email in the U.S. are more closely ranked: Sender is the most important followed by Content, Subject Line, and Offer/Promotion, which are all very close, and then Time of Day.Â
- 30% of U.S. participants said that Images/Video would make an email very memorable, compared to just 17% of participants in the U.K.Â
- In the U.S., 43% of participants said Critical Information in and email would strongly influence their decision to click on a link within, while only 29% of those in the U.K. said that would be a strong influence.Â
- 53% of participants said that the number of messages in their inbox was something they found frustrating, but only 40% of U.K. participants were frustrated by the number of messages.
- 37% of U.K. participants said they Sometimes switch from opening messages on their phone to opening messages on their computer compared to just 28% of U.S. participants.Â
- In the U.S., 62% of participants want just a few sentences in their emails, and 33% want 1-3 paragraphs. In the U.K., participants appear to want more content, with 56% wanting a few sentences, and 41% wanting 1-3 paragraphs.

Highlights and Takeaways for Email Senders
Ensure Correct Email Delivery and Placement – Incorrectly placed email, like when an expected email ends up in the spam folder, frustrates recipients. Learn more about improving your email deliverability in our Email Deliverability Guide.Â
Know Your Customers – Depending on the demographics of your customers theyâre going to be more or less willing to engage with emails that have multiple images, videos, or GIFs. If your customer or user base is made up of mostly Baby Boomers, consider leaving those things out of your next campaign. Or better yet, segment your recipients and create emails that theyâre more likely to appreciate upon opening.Â
Be More Selective – Senders should be more selective with the messages they choose to send recipients. In 2019, recipients are receiving more email than ever before, and companies are sending 8.3 messages per month. In order to stand out to recipients, senders should make sure they’re sending messages recipients are interested in and will value.Â
Make Sure Your Messages are Valuable – Recipients are more selective on what they will click than ever before. Even though the open rate dropped to 14.5%, the click to open rate also continued its drop. This means recipients are likely to open an email, but less likely to click on anything. Try to provide recipients with valuable messages that they want to receive.Â
Experiment With Frequency – Senders should continue to experiment with their sending frequency. Rather than sending many emails to all of their recipients, try sending fewer messages to more targeted groups to see if your engagement improves.Â
Optimize for All Countries – Make sure your email is optimized for inbox providers across the world. Email is one of the most commonly used communication channels in the world. Make sure your messages are getting delivered correctly by properly authenticating your messages. Â
Don’t Worry About When to Send – Email is a part of life for nearly everyone, and people with email addresses are typically checking their inboxes multiple times a day. This means that things like the time of day they received their messages are less important than ensuring the content of the message is valuable to each recipient you’re sending to.Â
Including Emojis – While it may spice things up a bit, including an emoji isn’t always worth it. Depending on the age of your customers, emojis may come across as unprofessional or spammy, and not as playful and interesting as you may think.Â
Content is Important – Many email senders think that there’s going to be some silver bullet they can add to their program, or use in a subject line that will unlock a lot of clicks. This isn’t the case. The one thing senders should think about is providing their recipients with messages they want. Think about segmenting your list and sending more targeted messages to groups of people with specific products or offers that they’ll want to receive.Â
Keep it Simple – Email recipients have been using email every day for a long time now, so they’re very aware of what an email should and should not look like. Rather than trying gimmicky things like flashy GIFs and videos, multiple images, or super long newsletters, you’re better off providing a well-designed email with a few sentences of content and a couple of images that illustrate your offer.Â
Double-Check Your Work – Grammar and spelling mistakes were some of the biggest turn-offs when it comes to email. Make sure your emails are error-free before hitting the send button.

Metrics Definitions
Aggregate Open and Click Rate: These are percentages of all unique messages sent by a segment that were opened or clicked. Messages that are clicked or opened more than once are not double counted.
Aggregate Delivery Rate: Percentage of all messages sent to valid addresses that were not rejected by the inbox provider.
Aggregate Spam Rate: The percentage of all unique messages that were marked as spam.Â
Mobile Ratios: Using the recipient device information inferred using the method described above, devices were categorized as mobile or not mobile. These ratios are the distinct count of mobile/non-mobile devices seen divided by the total distinct count of devices seen. Each device is counted only once per recipient.
Aggregate Monthly Send Rate (Send Frequency): This is the number of unique messages on a per sender per recipient basis. It tells you how many messages an average recipient might see from an average sender in a particular segment.
Aggregate Click-to-Open Rate: This is the ratio of unique clicks to unique opens; duplicates are not counted. This answers the question: âOf the emails that were opened, what percentage were clicked?â It can be thought of as a proxy for content quality.
