How to switch email platforms without losing your buyers

The order you do this in matters more than which platform you pick. Get it wrong and you email a paying student a pitch for the course they already bought.

What this is: the running order and the traps, drawn from what the platforms document about their own imports, exports and cancellation terms, checked 6 September 2026. What it is not: a screenshot walkthrough of a migration we ran ourselves. When we have run one end to end, we will publish that separately and say so.

  1. 1

    Export before you do anything else

    Get a CSV of your list out of the old platform and save it somewhere that is not the old platform. Do this even if you are only thinking about moving. Some platforms cut off access to your contact data the moment you cancel, so the export has to happen while the account is still live.

    ActiveCampaign is the clearest example: their own terms say that on cancellation you will not have access to, or be able to restore, any contact data.

  2. 2

    Write down who is a buyer and who is not

    This is the step people skip and regret. Your export is just names and emails. The knowledge that row 412 bought the course and row 413 downloaded the free thing lives in tags, and tags do not always survive a move. Before you import, make sure your CSV has a column that says which is which.

    If you lose that distinction you will email a paying student a sales pitch for the course they already own. That single mistake costs more goodwill than the migration saves in money.

  3. 3

    Bring buyers and non-buyers over as two separate lists

    Upload them as two files, not one. Different tools call the result a group, a list or a tag; whatever the name, the point is that afterwards you can still tell your paying students apart from everyone else. It takes five extra minutes and it is the whole reason step two exists.

  4. 4

    Build the welcome emails before you send anyone to the new tool

    A welcome sequence is the two or three emails that go out on their own when somebody new joins your list. Move your signup form across before those exist and new people get nothing at all. Write them first, sign yourself up to check they arrive, and only then change the form on your site. Check your plan can send them automatically at all: most free plans cannot.

    Of the 14 platforms we checked, 6 can run an automated sequence on the free plan: MailerLite, Omnisend, Sender, Systeme.io, EmailOctopus, Brevo.

  5. 5

    Start with a few emails, not all of them at once

    Gmail and Outlook decide whether to trust a new sender by watching its first few sends. Email your most active readers first, a few hundred at a time, before you mail everyone. Writing to your whole list on day one from a brand new setup is the quickest way to land in the spam folder.

  6. 6

    Keep the old account open for one full billing cycle

    Do not cancel the moment the import finishes. Leave the old account running until you have sent at least one real campaign from the new one and confirmed it arrived. Cancelling is the irreversible step, so it goes last.

The moves we can answer step by step

The steps above hold for any move. For these, we hold enough of both vendors' own published terms to tell you what comes across, what you build again, and what you must do before you cancel.

Moving to a free plan that can actually automate

Step four is where most moves stall, because the new platform's free plan will not run a sequence. 6 of the 14 we checked will.

Questions before you move

Will I lose subscribers when I move platforms?
Not from the export itself. The usual loss happens afterwards: some tools email everyone you imported and ask them to confirm they still want to hear from you. Most people never open that message, so they go quiet and you lose them. Before you import, look through the new tool's import settings for anything about asking subscribers to confirm again, and turn it off if it lets you. Which platforms ask, and which start your automations on import, is on the page about importing your list, quoted from each platform's own help pages.
Do any platforms move my list for me?
Some offer it, but always with conditions attached, so read the fine print. Kit: They will migrate your setup for you free, but only if you sign up for a paid plan first. Their words: "we can help move yours to Kit for free if you sign up for a paid plan". Sender: Done-for-you migration is free, but only on an annual plan with 20,000 or more subscribers. Below that you import it yourself.
Should I cancel the old account straight away?
No. Export first, migrate, send one real campaign from the new platform, and only then cancel. This matters more with some than others: ActiveCampaign's terms say access to contact data ends at cancellation. beehiiv is the gentlest of the ones we checked: cancelling there drops you to the free plan and keeps your data.
How long does moving actually take?
A straightforward list with one welcome sequence is an afternoon. The work is not the import, it is rebuilding automations and forms. Systeme.io, which does offer a done-for-you migration on its higher plans, says its own team averages 17 days for a full business migration, which tells you something about the upper end.

Not sure which platform to move to yet?Answer 5 questions and we will narrow it down, or see the head to head pages if you are down to two.

Not sure you need to move at all?Three of the four main course platforms already send an automated welcome sequence, so it is worth checking before you start.
