Import Suppression Lists

This feature requires Manager user level or higher.

To protect against accidentally re-adding invalid, stale, or cleaned subscribers to your active list, you can import contacts as unsubscribed to create a suppression list.

Each list in your MailChimp account is separate from the others, so your suppression list won't be global. You'll need to create a separate suppression list for each list in your account.

In this article, you'll learn how to set up a suppression list from a CSV, TXT, or Excel file.

Before You Start

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

  • To complete this process, you need an existing list in your account. Don't have one? Create a new list.
  • Suppression lists only require an email address field. Make sure your suppression import file does not contain additional fields or subscriber information.
  • Only import suppression lists to the Unsubscribed section in your account. If you need to import active subscribers, import to the Subscribed section.
  • Do not import active subscribers into the Unsubscribed or Cleaned sections.
