Email List Cleaning: 8 Best Practices To Ensure Better Engagement [+Tools]

So you followed all the steps to build and nurture your list, but what happens when your engagement rates start declining, and you receive more soft and hard bounces than you expected? Well, in this case, it’s time for some email list cleaning!

This process, also called email scrubbing, will allow you to remove outdated emails, spam accounts, and disengaged contacts to increase your engagement rates and return-on-investment.

Below, we are going to take a more detailed look at:

  • The reasons you need to keep your lists clean
  • Some best practices to make it happen
  • A few tools to get started

Now let the email list purge begin!

Why Is Email List Hygiene A Necessity?

Apart from ensuring a high engagement rate, maintaining a clean email list will also boost your inbox placement. This means that your audience will be able to receive your messages as you’ll have a high email deliverability rate!

But how do your email lists get “dirty” in the first place? Well, there are numerous reasons for that. The most common ones include human error, duplicate emails, invalid email addresses, spam accounts, disengaged users who haven’t unsubscribed, and disposable emails.

By removing these “bad email addresses,” you will have a list of valid email addresses and engaged users that will help you achieve high conversion rates.

Of course, your deliverability isn’t the only thing affected by unchecked email databases. Among other things, neglecting to perform regular email cleaning will eventually:

  • Harm your email sender reputation, i.e., the score assigned to you by Internet Service Providers (ISPs)
  • Result in multiple email bounces
  • Increase your email marketing cost and impact your lead generation efforts negatively
  • Lead to an increased number of spam complaints that will harm your deliverability
  • Give you a high bounce rate and unsubscribes

Email scrubbing will help you avoid all of the above, improving your deliverability metric, open rates, and click-throughs. Also, if email providers like Gmail, Outlook, and Yahoo think that you’re spamming your audience, they will automatically send your messages to the spam folder.

So, if you notice low open and click-through rates, high bounces, and you receive multiple spam complaints, it’s time to perform an email list purge.

8 Email List Cleaning Best Practices To Nail Inbox Placement

Below, you’ll find some of the best ways to nail email scrubbing in simple steps. Let’s see!

1. Plan Your List Cleaning Process

Let’s start with a question: How often do you need to clean your email list?

If you thought once in a while, then you need to reconsider. Cleaning your contact list is an ongoing process that requires time and effort. As your list grows, you need to perform frequent checks to ensure that it is free of bad email addresses. But how frequently should you do it?

Well, depending on your email list growth rate, performing an email scrub every two months is an excellent way to keep your contacts in order. Of course, you should always check your metrics (open rates, bounces) to determine whether you need to run an emergency email scrub or make it more frequent.

Planning your process is the best way to start. So here’s what you need to do to create an effective one:

  • Set up a consistent list cleaning schedule
  • Assign dedicated people to perform the task
  • Have the tools and resources you need to do it

A successful email list cleaning process needs to rely on frequency and consistency. So to succeed, you first need to understand that this isn’t a single-time thing but an ongoing task.

Moreover, creating a list cleaning calendar is perfect for reminding you and your team when you need to reorganize your contacts. So make sure to craft one and incorporate it into your email marketing calendar!

2. Set Up A Confirmation Message

Identifying and removing “bad email addresses” from your list can be a tedious task. But what if you can minimize the number of invalid or duplicate contacts right from the start?

Well, setting up a confirmation email is the easiest way to nail email validation without using additional tools. All you have to do is to adopt the double opt-in method and prompt your new subscribers to confirm their email address as Merc Clothing does:

This extra step is necessary to avoid adding unconfirmed or spam email addresses to your contact list. Sadly, a large number of businesses aren’t using double opt-in, especially in the US, where the GDPR law isn’t in effect. While double opt-in d adds an extra step to the process, you should use it to minimize the number of “bad emails” ending up in your list.

So adopting the confirmation message is the first step to creating an effective list building process that will save you the trouble of removing invalid and duplicate email addresses.

Now let’s move on to what you can do to optimize your existing mailing lists.

3. Set Criteria For Your Disengaged Subscribers

Now the next question is how do you define a disengaged subscriber? Well, to do so, you need to set some criteria as to what “disengaged” means.

For instance, a recipient who interacts with 70% of your email marketing campaigns is interested enough to engage with you. On the other hand, someone who only opens 20% of your messages may show little to no interest in your business.

Establishing specific criteria to spot your low-engagement subscribers is the first step to performing a successful email list cleaning.

So when you find them, you can:

  • Start removing duplicate email addresses from the list
  • Clear out subscribers who marked you as spam to avoid having your deliverability harmed by spam filters
  • Find and separate your soft from your hard bounces.

Identifying your disengaged audience accurately will help you perform more effective email scrubs. Also, the above process will allow you to filter your contacts, discover patterns and then create the perfect strategy to power up your email list hygiene!

Now that you know who needs to go, let’s see what you can do next!

4. Improve Your Segments

Segmenting your audience is one of the most crucial list building tactics to deliver targeted content. As you know, you can group your subscribers and customers based on different criteria, like their demographics, location, and so on.

However, did you know that you can also divide your audience based on their email activity? For example, you can group your non-openers and target them anew with specific messages to see whether they will interact with your campaigns or not.

Similarly, you can generate reports to discover which email addresses bounced. If they were hard bounces, then you need to remove them from your list without a second thought. However, if it’s a soft bounce, you can try sending those contacts another email in case their inbox was full, or the server was down.

Paying attention to your segments and reorganizing your contacts is essential to ace your email list management and boost your email metrics. So make sure to revisit them frequently to make sure that you deliver the right content to the right people!

5. Target Your Audience with Re-Engagement Campaigns

Removing non-openers and disengaged users is the easiest thing to do. Nevertheless, if you want to build an effective list, you need to establish relationships with your audience.

As you know, the reasons for disengagement vary, with the lack of engaging content being the most common. Sometimes, your subscribers may also be experiencing “email fatigue,” so you can’t be sure why they didn’t open your recent campaigns.

The best way to get them interested in your business is to target them with smart re-engagement campaigns. Here’s an example by Levi’s:

Subject line: Just for you… because it’s been a while.

levi's re-engagement campaign example

Your re-engagement campaigns need to have the right incentive to get your subscribers to act. For instance, you can deliver special discounts and exclusive deals like the above example or create unique content to nurture them anew.

Apart from offering them an irresistible offer, you can give your subscribers the opportunity to choose the number of emails they want to receive from you or the type of messages they prefer. This way, you will improve your segments and the health of your list.

6. Use the Unsubscribe Button to Your Advantage

One of the most essential elements of a newsletter campaign is your unsubscribe link. This button, usually found in the email footer, allows your interested contacts to remove themselves from your list easily.

Making your unsubscribe buttons clear and visible will help you power up your list cleaning efforts and give your disengaged audience a quick way out. While most email marketers add unsubscribe links in the footer, you can also place them above the fold to make the process faster.

Giving your disengaged subscribers a way out is one of the simplest ways to keep your email list clean. Also, don’t forget that hiding the unsubscribe link will trigger spam complaints. So being transparent and letting your unengaged contacts go is more preferable to getting flagged as a spammer or ending up on a blacklist.

What’s more, it’s good to know that most email marketing services like Moosend or Mailchimp will automatically add an unsubscribe button when you craft an email newsletter to minimize the risk of sending messages without one!

7. Keep Your Lists Clean with Marketing Automation

Most email service providers (ESPs) out there will offer you marketing automation options to streamline your efforts. As a tool, creating automated workflows will help you target your audience with the right message at the right time.

For email list cleaning, you can leverage this feature to set up sequences based on specific rules and subscriber actions. For instance, crafting a workflow to remove bounced email addresses is perfect for automating your list cleaning process!

Similarly, you can choose various triggers/actions to keep your list up-to-date. For example, you can use marketing automation to improve your list by creating new segments with your non-openers or low engagement contacts.

Moreover, having a lead scoring model in place is also a great way to discover your most active users and vice versa!
