Prepare a Constant Contact List for Import

If you've decided to switch from Constant Contact, you'll need to filter and organize your Constant Contact list before you import it to Mailchimp.

Mailchimp tracks and removes undeliverable addresses each time you send a campaign to keep your audience healthy. Although Constant Contact removes unsubscribed addresses, they don't manage bounced addresses this way. To import a clean, active list to Mailchimp, filter the bounced addresses before you start.

In this article, you'll learn how to prepare your Constant Contact list for import, and export your undeliverable contacts.

Before you start

• You must remove the bounced email addresses from your Constant Contact list before you import those contacts to Mailchimp.

Remove bounced addresses from Constant Contact

To filter bounced addresses out of your list, follow these steps.

1. Log in to your Constant Contact account.
2. Navigate to the Reporting section.
3. Scroll to the Detail section, and click the name of a recent campaign that was sent to all or most of your active contacts.
4. In the campaign report, click Bounced.
   
5. Click the Display drop-down menu, and choose Recommended for Removal.
   
6. Check the box to select all contacts in the Recommended for Removal category.
   
7. Click Remove Emails.
   
   Now your campaign's bounced emails are in the Unsubscribed category of All Contacts.

Export unsubscribed addresses from Constant Contact

Now that your bounced addresses are in the Unsubscribed category of All Contacts, you can export that file as a CSV. Visit Constant Contact's help center for instructions on how to export this file.

After you've downloaded this file from Constant Contact, you'll import those contacts as Unsubscribed to create a suppression list in your Mailchimp audience.

Import undeliverable addresses to Mailchimp

To ensure that undeliverable addresses are marked appropriately in Mailchimp, you can import them as Unsubscribed to act as a suppression list. If a contact signs up for your email marketing again, we'll change their status from Unsubscribed to Subscribed so they can receive email campaigns.

To import the undeliverable addresses, export your unsubscribed contacts in CSV format and upload the file to Mailchimp as a suppression list.

Great! You've prepared your list and imported your suppression list. Learn how to import your addresses to Mailchimp.
