Import Constant Contact Lists to Mailchimp

You've started the process to switch from Constant Contact to Mailchimp, and now it's time to import your contacts. It takes a few steps to import your contacts to Mailchimp, but when you're done, you'll be ready to get started creating beautiful campaigns.

In this article, you'll learn how to move active contacts from Constant Contact to Mailchimp.

Before You Start

  • Prepare your Constant Contact list before you import to Mailchimp to ensure that only active, useable email addresses are added.
  • If you don't have an audience in Mailchimp, create one.
  • To save time, you can import all Constant Contact lists in one batch. We'll place all contacts in the same audience, and store sublist information in a group that you can view and send to later.
  • We can store up to 60 of your Constant Contact sublists.
  • Mailchimp only supports one email address per contact. We'll save any additional email addresses from your list as text fields.
  • To ensure proper formatting for certain features in Mailchimp, we'll merge your address data into one address field. To learn more about the address field, check out Format Guidelines for Your Import File.
