There are two primary ways to consolidate your audiences in Mailchimp: the combine audiences tool or a CSV import. When deciding which method to use, you'll want to consider the type of contacts you're working with and the amount of data you need to keep.
In this article, you'll learn about the ways to combine audiences in Mailchimp.
Things to know
If you have GDPR data, we do not recommend you combine audiences at this time.
Export and import
To consolidate all of your contacts and retain as much data as possible, we recommend you export data from one audience and import it into your primary audience. This process requires different imports for each type of contact, and some information can't be transferred. For a breakdown of what information is and isn't included in an audience export, check out View or Export Contacts.
If you're working with a new or relatively unused audience and only want to combine subscribed contacts and their basic audience field information, such as name and email address, our combine audiences tool is a quick shortcut that may suit your needs.
