Hello there! Let’s discuss how to resolve the problem of overlapping subscribers in MailerLite. Having personally faced this issue, I know how frustrating it can be. But be assured, I have a solution for you!

What are overlapping subscribers?

First, let’s understand what overlapping subscribers actually are. When you have overlapping subscribers in MailerLite, it means that you have the same email address subscribed to multiple lists or groups within your account. This can cause issues like duplicate emails being sent to the same recipient, which is definitely not ideal.

Why do overlapping subscribers happen?

Overlapping subscribers can happen for a variety of reasons. It could be because you imported a list of subscribers without properly checking for duplicates, or maybe you accidentally added the same email address to different groups within your account. Whatever the reason, it’s important to fix this issue to ensure that your subscribers have a seamless experience.

How to fix overlapping subscribers in MailerLite

Now, let’s get to the good stuff – fixing those overlapping subscribers! Here’s a step-by-step guide to help you out:

  1. Step 1: Identify the overlapping subscribers
  2. The first thing you need to do is identify which email addresses are overlapping. You can do this by exporting your subscriber data from MailerLite and analyzing it in a spreadsheet program like Excel or Google Sheets. Look for duplicate email addresses across different lists or groups.

  3. Step 2: Remove duplicates
  4. Once you’ve identified the overlapping subscribers, it’s time to remove the duplicates. In MailerLite, you can do this by manually unsubscribing or deleting the duplicate email addresses from the respective lists or groups. Alternatively, you can use the MailerLite API to automate this process if you’re comfortable with coding.

  5. Step 3: Consolidate your lists
  6. After removing the duplicate email addresses, it’s a good idea to consolidate your lists or groups. This means merging similar lists or groups together to avoid future overlap. You can do this by exporting the subscribers from different lists, removing duplicates again if necessary, and then importing them into a single list or group.

  7. Step 4: Communicate with your subscribers
  8. Lastly, it’s important to communicate with your subscribers about the changes you’ve made. Let them know that you’ve fixed the overlapping subscriber issue and reassure them that they won’t receive duplicate emails anymore. This helps maintain trust and transparency with your audience.


Fixing overlapping subscribers in MailerLite might seem like a daunting task, but with the right approach, it can be easily resolved. By following the steps mentioned above, you’ll be able to eliminate duplicate emails and provide a better experience for your subscribers.

Remember, it’s crucial to regularly check and manage your subscriber lists to avoid any future overlap. By staying proactive, you’ll ensure that your email marketing campaigns run smoothly and effectively.

Happy fixing!
