Import Constant Contact Lists 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 a list 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 list, 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.

Export Active Contacts List

First, you'll need a CSV file of your Active Contacts from Constant Contact.

To export all your active contacts, follow these steps.

1. Log in to your Constant Contact account.
2. Navigate to the Contacts section.
3. Click Active to view your active contacts.
4. Check the box in the upper left corner of the table to select all active contacts.
5. Click Export.
6. In the Export pop-up modal, choose the fields you want to include. Email address is the only field that's required by MailChimp, and you can also include any additional fields.
7. Check the List box if you want to transfer your sublists names into your MailChimp list.
8. Click Export Contacts. When your export is complete, a message will appear at the top of the screen.
9. Click Download CSV.

Import Contacts to MailChimp

Now that you have your CSV, you'll import active contacts to your MailChimp list.

1. Log in to your MailChimp account.
2. Navigate to the Lists page.
3. Click the drop-down menu next to the list you want to work with, and choose Import.
   
4. Choose Integrated service, and click Constant Contact.
   
5. Click Next.
6. To upload your CSV file, click Browse and choose the file from your computer.
   
7. Check the box next to I understand that my billing plan may be automatically upgraded.
8. Click Next to move on to the Import Subscribers step and match the columns in your CSV file to the columns in your MailChimp list.
   
9. If the first column is matched and labeled correctly, click Save. For example, the Email Address column looks like this.
   
   We automatically match the column in your import that contains email addresses to the required Email Address field in your MailChimp list.
10. Click Save on the Email Lists column to transfer your Constant Contact list names to MailChimp.
    
11. On the additional columns, click Save, or click the drop-down menu to select a different field type. For columns whose labels did not transfer from your import file, choose New Column name, and type in your label. Or click Skip to exclude the column from the import.
    
12. Repeat Step 11 for all unmatched columns. You must match or skip every column to complete your import. We'll display a success message when you're done.
    
13. Click Next to review your final import settings.
14. On the You're all set to import! screen, review the settings for your import. We'll display the method you chose for your import and the number of columns you matched. You can click Details to view which columns you matched to fields in your list, or Edit to make changes.
    
15. After you've reviewed your settings, click Import.
