ActiveCampaign is a natural next step for Klaviyo users who need stronger CRM alongside their email marketing. If you are expanding beyond e-commerce into service or B2B, ActiveCampaign's CRM and automation combination is hard to beat.
This guide covers everything you need to migrate from Klaviyo to ActiveCampaign without losing subscribers or breaking your automations. Estimated time: 1-2 days.
What transfers and what does not
| Item | Transfers? | Notes |
|---|---|---|
| Contacts and email addresses | Yes | Via CSV export/import |
| Tags and segments | Partial | Export as custom fields, remap on import |
| Custom field data | Partial | Transfers if mapped correctly during import |
| Unsubscribe history | Yes | Import as suppressed contacts |
| Email templates | No | Need to be rebuilt in ActiveCampaign |
| Automation workflows | No | Need to be rebuilt from scratch |
| Campaign history | No | Historical stats stay in Klaviyo |
Step-by-step migration guide
Sign up at try.activecampaign.com before doing anything else. Keep your Klaviyo account running throughout the migration: do not cancel it until everything is confirmed working in ActiveCampaign.
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.
In Klaviyo, 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.
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.
Screenshot or document all your active automations in Klaviyo 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.
Build your signup forms in ActiveCampaign and replace the Klaviyo embed codes on your website. Test each form to confirm subscribers land in the right list and trigger the correct automation.
Send a test campaign to yourself. Trigger your automations manually. Check every link. Confirm your unsubscribe flow works correctly. Only cancel Klaviyo once you are fully satisfied that ActiveCampaign is working as expected.
Once ActiveCampaign is fully operational, cancel your Klaviyo 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 you need a CRM alongside your email marketing and are moving beyond a purely e-commerce model. It is not as strong on e-commerce-specific flows as Klaviyo, but for businesses diversifying their model, it is the stronger all-around platform.
