Use the Combine Lists Tool

If you have multiple lists in your MailChimp account, it may be helpful to combine them into a single master list. This can reduce the cost of your Monthly Plan and streamline subscriber organization, because it removes duplicates from your list.

In this article, you'll learn how to combine your MailChimp lists with the combine list feature.

Before You Start

Here are some things to know before you begin this process.

  • To combine lists in MailChimp, you'll need to have two or more subscriber lists that you can merge into one master list. Decide which of your existing lists you want to use as your master list, or create a new list to use.
  • List actions can't be undone, so be sure to back up your existing lists. Keeping a backup is a safeguard, in case you change your mind or something goes wrong.
  • Combining lists only saves subscriber data, and doesn't carry over campaign activity or purchase history.
  • For seven days after you send any campaign, automation email, or RSS campaign, we place a temporary hold on bulk list actions. If you've recently sent to one of your lists, you won't be able to combine it until seven days later.

Combine Lists

After you've backed up your lists and exported any data you want to keep, you're ready to merge your lists. 

To combine your lists, follow these steps.

  1. Navigate to the Lists page.

  2. Find the list that you want to combine with your master list. For example, if you have a list called "New Alumni," and you want to combine it with a master list called "Hathaway Alumni," you'll work with your "New Alumni" list.

  3. Click the drop-down menu next to the list you want to combine with your master list, and choose Combine lists.

    Repeat this process for each of the lists you want to combine. On your master list, the subscribers you added will have a signup source of "Unknown."

Next Steps

  • When you've finished backing up and combining your lists, you can delete your old lists.

  • Be sure to update any signup form URLs, and pop-up, embedded, or hosted forms to match your new master list.
