Step-by-step migration guide

Step 1
Start your ActiveCampaign free trial
5-10 minutes

Sign up at try.activecampaign.com before doing anything else. Keep your Constant Contact account running throughout the migration: do not cancel it until everything is confirmed working in ActiveCampaign.

Step 2
Authenticate your sending domain in ActiveCampaign
15-30 minutes

Add your domain to ActiveCampaign and follow the DKIM authentication instructions. This improves deliverability and ensures your emails arrive in inboxes, not spam folders. Complete this before importing any contacts.

Step 3
Export your contacts from Constant Contact
15-30 minutes

In Constant Contact, go to your audience and export your full contact list as a CSV. Make sure to include all custom fields, tags, and segments. Export your unsubscribed contacts separately: you will need to suppress these in ActiveCampaign to stay compliant.

Step 4
Import your contacts into ActiveCampaign
15-45 minutes

Upload your CSV into ActiveCampaign and map each column to the correct field. Import your unsubscribed contacts as suppressed. Review the import report carefully before proceeding: fix any mapping errors before building automations.

Step 5
Rebuild your automations in ActiveCampaign
1-3 hours

Screenshot or document all your active automations in Constant Contact before rebuilding them in ActiveCampaign. Start with your highest-priority flows: typically your welcome series and any active nurture sequences. Do not activate them until you have tested them with your own email address.

Step 6
Recreate your signup forms and update your website
30-60 minutes

Build your signup forms in ActiveCampaign and replace the Constant Contact embed codes on your website. Test each form to confirm subscribers land in the right list and trigger the correct automation.

Step 7
Send a test campaign and confirm everything works
30-60 minutes

Send a test campaign to yourself. Trigger your automations manually. Check every link. Confirm your unsubscribe flow works correctly. Only cancel Constant Contact once you are fully satisfied that ActiveCampaign is working as expected.

Step 8
Cancel Constant Contact
5 minutes

Once ActiveCampaign is fully operational, cancel your Constant Contact account. Check your billing date to avoid being charged for another month. Download any historical reports or data you want to keep before cancelling.

The bottom line

ActiveCampaign makes sense if Constant Contact's automation limits are holding you back or you need CRM features. Be prepared for a steeper learning curve and higher cost, but the automation capabilities are in a different league.
