Unlocking the Secrets of Sender Reputation: Your Key to Email Deliverability

All businesses have a reputation determined by their level of service, quality of goods, and reviews. However, your sender reputation is an entirely different ball of wax.

The above factors might influence which customers decide to give you their hard-earned money, but they have no bearing on whether your emails get delivered. That’s exactly what your sender reputation affects. Therefore, one of the most substantial steps to improving your email deliverability is fixing a damaged sender reputation.

In this article, we will examine email reputation in more detail, including what that is, how much it influences email marketing performance, how to check your email reputation score, and–most importantly–how to improve it.

What Is Email Sender Reputation?

Email sender reputation is a score that internet service providers generate to indicate that you’re a safe sender or a spammer. All companies have a sender reputation. Well, unless your startup is brand new and hasn’t sent a single email yet.

Each future message adds or detracts from your score. A higher score tells ISPs to send your emails to their recipient, as you’re a trustworthy sender.

ISPs can count on your emails to contain relevant content and legitimate links. They know you’re not emailing spam traps or dead addresses because you prune your list regularly.

The lower your score, the more red flags your emails raise to ISPs. If you read our guide on ISPs and email deliverability, you’ll recall that ISPs have the power to prevent your emails from reaching the recipients in their network.

It’s prudent for startups to learn their reputations from the get-go and strive to maintain a steady score so their ISPs can continue allowing their emails through.

However, you’re not a hopeless case, even if your reputation has already fallen by the wayside. You can take strides to improve it, falling back into the good graces of your ISP. We’ll discuss how later in this guide, so don’t miss it.

How to Check Your Email Sender Reputation

5 Ways to Improve Your Email Sender Reputation

Did the email deliverability checkers produce some less-than-desired results about your sender reputation? Your email list won’t receive your messages unless you change something, so how do you improve your reputation score?

Here are our suggestions.

Switch up your email marketing strategy

How many times can one person see the same old, same old? They get tired of it eventually and will begin disengaging. It begins with your audience not opening your emails anymore and sending them straight to the trash.

Then, when they still keep receiving emails from you, they’ll unsubscribe and report your messages as spam.

You must continually engage with your audience, changing your email content to keep it fresh and enjoyable to read.

Divide and conquer

Mass emails are a great way to tank your sender reputation. ISPs get suspicious about domains sending thousands of emails at once. Segmenting your audience and sending various segments emails at different times keeps you in the good graces of your ISP.

Your audience will also appreciate the tailored, personalized content that speaks to their needs, challenges, and pain points. They’re less likely to unsubscribe and report you for sending spam.

Prune your email list

Make it a habit to clean up your email list every month or several months. Use an email marketing tool like EngageBay to retarget your less active users. Then, sunset the email contacts that don’t open or interact with your emails.

These could be deactivated email addresses that an ISP could flag as a spam trap.

Check your blacklist status

Ipvoid combs through all the blacklist registries to determine if you’re on them. We discussed this earlier in our introduction to email deliverability, but once you’re blacklisted, you’re prohibited from sending emails.

Run a blacklist check at least monthly. What do you do if you find your name on a blacklist or several? You have a few options for removing yourself.

You can contact the blacklist provider and tell them there’s been a mistake and your name shouldn’t be on there. However, you can only use this approach if your email reputation is otherwise squeaky clean and it was a genuine mistake.

If you were placed on a blacklist because of a high bounce rate or other email errors, you must fix your mistakes first. Asking to get taken off a blacklist with a bad reputation won’t make it happen.

More than likely, you’ll have to go through an automated removal process. The automated process will remove blacklisted brands according to reputation. If your sender score is moderately low, you’ll get de-blacklisted faster than someone with a very bad score.

Improve your email list quality

Avoid getting blacklisted again by cleaning up the quality of your email list. Change your subscription policy, making it easier to unsubscribe. This will allow on-the-fence users to exit your email list without reporting you for spam first.

Losing subscribers doesn’t hurt your sender reputation, but spam complaints do!

Verify your emails using tools and A/B test your messages before you send them to keep content high-quality for an audience that deserves the best.
