How to move email platforms without losing your list
Switching email marketing tools is mostly a checklist problem. Here is what carries across, what quietly doesn't, and the order to do it in so no subscriber gets lost or emailed twice.
People put off switching email platforms for years, and it’s rarely because of the new tool. It’s the fear of the move: losing subscribers, breaking a signup form nobody remembers setting up, or emailing someone who unsubscribed back in 2023.
That fear is reasonable, but the move itself is manageable. It isn’t difficult so much as long, with a few steps that are easy to forget. Here is the list, in order.
What carries across, and what doesn’t
Your subscribers do. Every established platform will export your contacts as a CSV, and every one will import one. Custom fields such as first name, signup source or plan come along as long as you map them to matching fields on the other side.
Your unsubscribes and bounces must. This is the step people skip. The people who opted out, and the addresses that hard-bounced, need to go into the new platform’s suppression list so they never get mailed again. Emailing them would break your promise to them, and it’s the fastest way to damage your sender reputation on a brand-new account.
Your automations don’t. There’s no standard format for a welcome sequence or a branching journey, so these get rebuilt by hand. That’s a good moment to cut the ones nobody would miss.
Your signup forms don’t either. Forms embedded on your site, pop-ups and landing pages all belong to the old platform. Each one has to be found and replaced, or new subscribers will keep landing in an account you’re about to close.
Your history mostly doesn’t. Open and click history rarely transfers in a useful way. Export any reports you care about before the old account closes.
The order that avoids double-sends
- List everything that touches the old platform. Forms, landing pages, checkout integrations, your CRM, any automation tool in the middle. This list is the whole migration. Everything below is working through it.
- Set up sending on the new platform first. Add and authenticate your sending domain with the DNS records the new vendor asks for, before a single contact goes in. Your email provider’s setup guide will name the exact records.
- Rebuild the automations you’re keeping, and leave them switched off.
- Export and import contacts, suppression list included. Check the counts on both sides match before moving on.
- Swap the forms and integrations over, one at a time, from the list you made in step one.
- Turn the new automations on and the old ones off on the same day. That one day is what prevents someone getting two welcome emails from two platforms.
- Keep the old account open for a few weeks in case something was missed, then do a final export and close it.
Start the new account gently
A new sending account has no history with inbox providers, so check with your new vendor whether they recommend ramping up volume over the first few sends. Many do. Sending first to your most engaged subscribers, the people who opened recently, is a sensible default either way.
Which platform to move to
That depends on what you’re moving away from. Our email marketing shortlist covers three very different shapes: GetResponse bundles email with pages and funnels, AWeber keeps sending deliberately simple, and ActiveCampaign is built for people who really will build branching automations. If you’re choosing between the first two, we compared them directly.
Whichever you pick, the checklist above stays the same.
