Sender reputation is a major component of your email deliverability. That is why understanding the importance of it is crucial for maintaining your email communication. The bit that we all want to know is HOW to keep it decent and healthy! What steps and actions you should implement in your email sending practises to keep on getting your emails into your recipients’ inboxes?

Your reputation is impacted by several factors. Unsubscribe rate, spam complaints, bounce rate, your recipients’ engagement rates, being blacklisted or sending to spam traps. To secure your reputation you have to ensure that your list is well maintained! If your emails are actually being delivered into the inboxes, your readers do engage with your content. Plus no one will dare to mark you as spam.

What is email sender reputation?

Just to make sure that this article is about the sender reputation that you are interested in, let’s quickly sum up what a sender reputation is. It is a score that Internet Service Providers (ISPs) assigns to a sender. If a sender has multiple domains and sends emails from different IP addresses, each one of them will have its own reputation. The better the reputation is, the bigger the chance of getting your emails into your recipients’ inboxes. If the score will get below a certain threshold, due to bad sending practises, the ISP may put your messages to spam folders or even reject those. Understanding what factors actually impact the reputation is very difficult, as the reputation itself is not static. The things that were important yesterday, might not be enough today. 

Factors that impact the sender reputation

  • The number of emails sent
  • The number of complaints (how many recipients mark your email as a SPAM)
  • The engagement rates (open, reply to, forward, click rates)
  • Bounce rate (the quality of the email list)
  • Domain or IP blacklisted
  • The number of emails sent to spam traps
  • The number of unsubscribes from the email list.

It is unclear as which of those would be the most important, as each ISP decides which factors will impact the reputation score more heavily.  Undoubtedly every sender should always follow good sending practices!


How to protect the sender reputation?

In short: just be a good person on the Internet! Follow the simple rules, and by that keep your sending score as high as possible.
If you are using a new domain, make sure you have a good warm-up plan, before sending any mass email campaign!

List Management

Start with proper maintaining of your email list. Remove non-responders and clean it with email checker from undeliverable emails. Any email that might result in a hard bounce will affect your sender reputation.

Rates, rates, rates!

Always monitor your delivery and engagement rates. It will help you notice any abnormalities quickly so you can take appropriate repairing actions before it will actually turn in to full-on email disaster. If your open rates suddenly dropped from 20% to 5%, you will know that something is not right.

Respect your subscribers!

Remember that they’ve shared their email address with you, as you have promised them specific content around the subject of their interest. Therefore, make your content relevant, attractive and clickable! It will help you with keeping open rates high, as your subscribers will be actually keen to open your emails if your previous message was interesting and personalized.

 Stop from unsubscribing

Good content will also reduce the number of unsubscribers! Imagine that someone has subscribed to your newsletter to get the best cooking recipes. Instead, you’ve sent them emails with some other content, but no actual recipes! Can you blame them for unsubscribing?! Furthermore, if for some silly reason, you have decided to hide the unsubscribe button, well, your spam complain rates will explode! Let’s hope we don’t really have to mention the fact that if you are actually sending spam, this will kill your inbox placement quicker then you think!
All those metrics have an impact on your email sender reputation. Clearly interaction with your messages is crucial in securing your email deliverability.

Buy a list? NO!

Never use a purchased/rented/free email list! Those are usually packed with email addresses that you shouldn’t contact (invalid, spam traps, disposable). By emailing those you are putting your sender reputation at very high risk, and you might get yourself blocked from any email communication.
