Import Suppression Lists

To protect against accidentally adding invalid stale addresses to your audience, you can import contacts as unsubscribed to create a suppression list.

Each audience 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 audience 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.

  • Suppression lists only require an email address field. Make sure your suppression import file does not contain additional fields or subscriber information.
  • This suppression list process can't mark existing contacts as unsubscribed or cleaned. To mark existing subscribers as unsubscribed, use the bulk unsubscribe tool instead.

  1. Navigate to the Audience tab.
  2. If you have more than one audience, click the Current audience drop-down and choose the one you want to work with.
  3. Click the Manage Audience drop-down and choose Import contacts.
  4. Choose CSV or tab-delimited text file.
