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.
