How to Handle Email Bounces

Best Practices

What’s the best way to handle email bounces? Below are three best practices to employ when dealing with invalid email addresses. But first, let’s establish a basic understanding of the two types of bounces that you’ll find in your email stats dashboard.

Soft vs. Hard Bounce

A soft bounce is a temporary failure that happens when an email smtp server rejects an incoming message. This could be caused by a full mailbox or connection error. A soft bounce simply means that you can try to send your message again later when the condition has resolved.

A hard bounce is a permanent failure in which the host or recipient is unknown. This could be caused by a bad or expired email address. In this case you should not attempt to send the email again. Read More ›

How Email Delivery Directly Affects Your ROI

Carly Brantz Best Practices, Technical

Do you know how much each email delivery is worth to you? If so, then you have the power to calculate how much revenue you are losing each time email doesn’t make it to the inbox.

On average 20% of email goes undelivered or winds up in the spam or junk box. Using “back-of-the-napkin” math, you can quickly gauge the potential loss. For example, if you send 100,000 emails, only 80,000 of your emails are actually reaching your customers each month. If each email is worth $50 to you, then losing 20% of your audience translates into a significant loss of revenue. Read More ›

3 Ways to Use Complaint Feedback Loop Information

Best Practices, Technical

One of the main (and probably most important) reasons email goes undelivered is because subscribers are complaining about your messages. Subscribers complain to their ISP by marking your email as spam and these complaints affect your email reputation. Each ISP has a threshold for complaints and if you cross it, your email gets blocked at the gateway.

There are a number of reasons why subscribers complain about your email, but in order to find out whom and why, you need to have access to feedback loop information. Complaint feedback loops capture subscriber complaints for the ISPs, but the information is available to email senders if they sign up to receive the data. With access to the data you can do three things: Read More ›

NYT’s Study Showcases the Importance of Email Infrastructure

Company, Guest Post

Exactly how and why do we share online content? That is what the New York Times and Latitude Research set out to discover in their 2011 study, “The Psychology of Sharing.”

Surprisingly, during their survey of 2,500 self-described “medium-to-heavy content sharers” they found that good, old fashion email continues to be the number one sharing tool. Yes, the younger you are the more likely you are to utilize Twitter, Facebook, Google+ or something similar as a communications tool, but email for the most part remains the most popular way users choose to share news.

Plain Text Emails: Yes Design Still Matters

Carly Brantz Best Practices



Despite the prevalence of HTML email, plain text emails are still viable tools for soliciting a response from your subscribers. Plain text emails appear in place of HTML emails in certain email clients and are often used in transactional email and on mobile devices.

But just because it is plain text doesn’t mean it doesn’t need to be designed. In fact, the lack of the design options with a format that is inherently hard to read will challenge you to be more creative with your copy and delivery. Here are few tips on how to design and thereby maximize the effectiveness of your plain text messages. Read More ›

Five Design Tips for Optimal Email Deliverability

Best Practices, Technical

Design has become increasingly important in creating an enjoyable, and even acceptable, experience for today’s average web user. This trend is not going away. On the contrary, as users become more savvy and accustomed to friendly design, the bar for quality design will continue to rise.

However, good design does not necessarily mean fancy graphics and never-before-seen user interactivity, such as that which we find in the always innovative Google Doodles. Design often hinges more so on simplicity and functionality, as is the case with HTML emails. The importance of email design is two-fold: first, design plays a big part in getting your email into your customers inbox; once that hurdle is cleared, design helps encourage the user interaction that represents your true end goal.

Control Your Email Destiny with a Dedicated IP

Carly Brantz Best Practices, Technical

Most email service providers have been offering dedicated IP addresses for nearly a decade. We didn’t think this topic was particularly controversial, but an interesting industry post presented a unique view on this practice. While we appreciate the viewpoint of that post, we feel obligated to remind our readers why we believe that dedicated IPs are important and what role they can play in your email success.

Why would a sender need or want a dedicated IP rather than a shared IP?  It all comes down to the word dedicated. In this case it means there is an IP address dedicated for your exclusive use. Only your mail is sent via this IP and this means that any deliverability problems that arise only impact you and are a direct result of your practices. This is of course in stark contrast to a shared IP where your mail is bulked along with the mail of dozens or perhaps even hundreds of other senders and deployed from the same IP. This means any issues that arise may or may not be the result of your practices – and your reputation is only as good as the reputation of the worst sender on the IP. So if one sender rents a list from a disreputable vendor, gets a bunch of spam complaints and the IP ends up blacklisted your mail is blocked along with theirs. Read More ›
