Email list cleaning

Email list cleaning is a critical, but not super exciting part of any successful email campaign. With Mailgun, you can get a clean email list without having to do as much of the tedious legwork yourself.

The key to a high-performing email marketing program? Proper email list hygiene.

Everyone knows that proper dental hygiene starts with brushing and flossing. You may see your dentist every six months for a cleaning, but the best way to prevent cavities and keep your pearly whites clean is from boring, regular old routines you learned when you were little. You wouldn’t skip brushing your teeth, would you?

That’s exactly what email marketers do when they don’t practice good email list cleaning. Regularly removing duplicate email addresses from your list, performing an email list verification, and evaluating your segmentation matters for your success.

It may not be exciting, but we all have to do it.

With Mailgun, you can get a clean email list without having to do as much of the tedious legwork yourself. Our email checker does it all for you.

Why email list cleaning is essential: Deliverability

Have you cleaned your email lists lately? If you’re in email marketing, then a quarterly cleanup isn’t optional. Getting rid of email bounces can increase your email list quality. Otherwise, you’re dealing with a plummeting email deliverability rate, and that’s not fun. If your emails aren’t actually landing in inboxes, you can’t get conversions. That’s all of your marketing efforts wasted. International regulations like GDPR and CAN-SPAM make this even more important for legal compliance.

Going through email addresses to find ones that bounce due to grammar, syntax errors, or typos is time-consuming. There’s no way around it unless, of course, you use an email server that can automatically suppress emails to email addresses that have bounced. That’s where Mailgun comes in.

Do you have these four types of bad emails on your list?

Success for most email marketers looks like a rush of new subscribers and increased open rates, click-through rates, and conversion rates for their email marketing campaigns. But if you’re not monitoring these four types of bad emails, you’re putting your entire program at risk:

Bounces: Bounced emails are email delivery failures due to mailbox errors. “Soft bounces” means a subscriber’s mailbox is full or your email is not deliverable for a temporary reason. “Hard bounces” mean you’ll never be able to deliver an email to that address because it’s invalid, incorrect, or blocked. An email verification service can help you verify emails so this happens less frequently.

Inactive recipients: Are your email recipients actually opening their emails from you? Maybe they signed up using a secondary email that’s inactive, or they didn’t mean to opt in at all. Or perhaps they just aren’t as interested in your product or service anymore. You can raise the quality of your email list by periodically checking for inactivity and removing users who haven’t opened an email recently or introduce a segmentation program instead of sending catch-all emails to everyone.

Unsubscribes: If a user unsubscribes, they shouldn’t get another email campaign from you. But so many marketing programs keep emailing after unsubscribes, which leads to spam complaints. An email service provider (ESP) or email marketing service can help you keep track and get rid of users who don’t want to hear from you. This is extremely important for your spam reputation. Marketing automation tools can automatically remove users who request to be removed, freeing up your time for other valuable tasks.

Complaints: Every time an email user marks your email as spam, you get a ding on your IP and domain reputation score. As soon as a subscriber marks you as spam (whether you send spam emails or not!), you must remove them from your email list — not just because of your sender reputation, but because they no longer want to receive emails from you. Failure to do so can result in blacklists (also called blocklists) which prevent your organization from emailing anyone who uses that inbox provider like Gmail or Yahoo. Keep your sender reputation where it needs to be by staying aware of spam complaints as they happen, and taking action to make sure they don’t happen again.

How to make email list cleaning easy

That’s a lot of bad email types. To manage your email list manually, you’d have to conduct frequent list cleanings by hand, including bulk email checks. And chances are, you just don’t have the time or manpower.

It doesn’t have to be a time-consuming process with an email list cleaning tool. Beat the spam folder trap by using an email list hygiene tool to clear out email addresses that shouldn’t be there. With real-time email verification and other list services, you can take some of the pressure off and still reap the benefits of using a clean list.
