Determining the best time or the best day to send your email marketing campaign is an essential piece of your overall email marketing strategy.
And for good reason.
High-quality content timed to arrive in your recipient's inbox at the right time can help increase both your engagement and delivery rates.
Ever feel like you're shouting into the void when you hit "send" on your email campaigns? You're not alone. Timing is everything in email marketing—it can mean the difference between your message landing with a bang or fizzling out unnoticed.
Although there’s no magic answer to when you should send your email campaigns, there’s a lot in your control to test and find your email send time “sweet spot.”
Whether you use automation or not (we provide tactics for both scenarios below), there is a method that will help you achieve optimal send times. The tips and insights below can help you get started and help you dial-in your send time so your email campaigns have the highest chance of being read.
Wondering where to start? Consider looking at historical data around send times and correlating engagement rates. We pull send data from our senders over holiday time periods here at Twilio SendGrid, and we’ve found that during Black Friday and Cyber Monday, the peak send time across senders was 7 AM, and that peak opens occurred between 8 AM and 9 AM MDT.
And most recently, over the Memorial Day weekend, we saw that the peak send time was also 7 AM. But when it came down to analyzing the most common open times, results varied so much that our data scientists couldn’t find a statistically significant time that people were most likely to open an email.
Starting with a Tuesday send time at either 7 AM or 11 AM will be solid places to start and use as a control in your email send testing. Again, the best way to determine your optimal send time is to test (and keep testing) variables until you find enough statistical significance to conclude that one time is better than another.
Keep in mind all the other variables in place that determine optimal email send times.
For example, those who are in the market to purchase software are probably very unlikely to want to purchase or engage with you over the weekend because they aren’t at work.
But if you email on behalf of a B2C brand, the weekend sends might be some of your highest-converting and engaging campaigns. I know for a fact that the majority of my online shopping occurs on Saturday mornings on the couch over coffee, and I’m often digging through my inbox to find that promotion that I’m looking to use.
Here at Twilio SendGrid, I work on our monthly blog digest (psst: you can sign up for that here), and I’m constantly tweaking the send time but have generally landed on sending the campaign out on either Tuesday or Wednesday between 10 and 11 MST.

The best time to send an email campaign will largely depend on your email purpose and your audience. For example, the best time to send an email blast to your entire audience won't be the same as when you send a promotional coupon email to a segment.
The best time to send an email blast depends on various factors, including your target audience, industry, and the purpose of your email campaign. While there is no universal "one-size-fits-all" answer, here are some general guidelines to consider when determining the best time to send your email blast:
Know Your Audience: Understand your target audience's habits and preferences. Consider factors such as their time zone, typical work hours, and leisure times. A B2B audience might respond differently to email timings compared to a B2C audience.
Experiment with Timing:Conduct A/B tests to determine which timing resonates best with your audience. Send your email to different segments at various times and days, and analyze the open and click-through rates to identify patterns.
Avoid Busy Times: Avoid sending emails during peak hours when people are overwhelmed with their inboxes. Mondays and Fridays, for instance, might see higher email volume and lower engagement. Midweek mornings or early afternoons often yield better results.
Consider Time Zones: If your audience is spread across different time zones, schedule your email to reach them at a reasonable time. You might segment your list based on geographical locations to ensure optimal timing.
Device Usage: Morning and evening times are often popular, as people tend to check emails on their commute or during downtime.
Avoid Holidays and Weekends: While weekends might seem like a good time to catch people's attention, many people use weekends for personal activities and may not engage with marketing emails. Similarly, holidays and long weekends might result in lower engagement.
Industry Trends: Research your industry's email behavior trends. Some industries, like retail, may see better engagement during weekends and holidays, while others, like professional services, might have higher engagement during weekdays.
Here are some general guidelines and trends to consider when determining the best time to send promotional emails:
Weekdays, Midweek: Promotional emails often see higher engagement when sent on weekdays, especially Tuesdays, Wednesdays, and Thursdays. These days tend to have lower email volume and higher open rates compared to Mondays and Fridays.
Morning and Early Afternoon: Aim to send promotional emails during the morning hours (around 9-11 am) or early afternoon (1-3 pm) when people are likely to check their emails during work breaks.
Avoid Early Mornings and Late Evenings: Sending emails very early in the morning or late at night might result in your emails getting buried in recipients' inboxes or being ignored altogether.
Lunch Breaks: Sending emails during lunch breaks (12-1 pm) can also be effective, as many people check their emails while taking a break.
To start simple, include a control send time and a variable send time to A/B test your send time. In Twilio SendGrid’s Marketing Campaigns, you can set this up to automatically switch to the winning version after a set amount of time or variance has been reached. For a deeper dive into A/B testing, check out Twilio SendGrid’s email A/B best practice guide.
Here are some ideas of what variables you could decide to test first to see what is resonating best:
Time of day - day vs. evening
Day of send - week vs. weekend
Specific time blocks or periods - start of workday vs. end of workday vs. lunch
Once you’ve determined what day and what time of day is working best for you, you can make granular tweaks to try and be the top email in your recipient's inbox.
Avoid sending at the very top of the hour or 15, 30, or 45 minutes past the hour. Why? Most marketers use these times to send their email campaigns because they come to mind first.
This practice causes a backup at the ISPs which can cause your emails to be deferred. Instead schedule your 11 am emails for 10:55 instead (and don’t forget to observe and record the results!)
Some ISPs have told SendGrid delivery consultants directly that the ideal time for marketers to send their campaigns is during non-peak times like 7, 21, or 36 minutes past the hour. Sending at these non-peak times will increase how fast your messages are delivered.
What if your email recipients live around the world, and you don’t have the capabilities or resources to segment out your email list for each time zone to receive their email at the right time? Consider following the sun.
Follow the sun campaigns are typically sent to recipients at or around the time that the sun is rising in their geographic location.
Following the sun gives you a higher probability that your message will be at the top of recipients’ inboxes. This will also reduce the burden on the ISP because the campaign will be split into 38 smaller sends based on time zones (if you have a global audience across all time zones).
Depending on the capabilities of your ESP, you will need to figure out how to tactically send to your audience at the optimal time. Before you can implement this strategy, you will need to know the general geographic location of your recipient.
When it comes to transactional email, which is typically triggered by an action the recipient has taken, send time can be less critical. This is because transactional email is not sent in bulk to hundreds of thousands of recipients at once, it happens organically. Read more about the differences between marketing and transactional email.
Finding the best time to send your email isn't a one-and-done deal—it's an ongoing process of testing, learning, and refining. Remember, while timing is important, it's just one piece of the email marketing puzzle.
Even the most perfectly timed email won't engage your audience if the content doesn't resonate. Always keep in mind the following when determining when to send your email campaigns:
Start by looking at performance data benchmarks
Consider the type of email you are sending and the capabilities of your ESP
Send at “odd” times instead of at the top or bottom of the hour
Test, test, test!
Remember that email send time is only a piece of your email marketing program. And no matter how optimized your email send time is, if you aren’t providing engaging and valuable content, you won’t persuade users to keep opening and engaging with your emails.
