Do my subscribers need to re-confirm when I move?

No. Changing provider does not need fresh consent. The importer carries the consent evidence Buttondown kept across with each contact. Contacts with no evidence at all are left out rather than emailed, and you get the list of who they were so you can decide.

What happens to people who unsubscribed on Buttondown?

They stay unsubscribed. Suppressions are imported first, before any address that can receive mail, and the CSV importer's status column turns Buttondown's unsubscribed, bounced and complained rows into suppression entries with their original dates. Move-in also syncs unsubscribes from the old platform for 30 days after cutover.

Can I move some sites and leave others?

Yes. Each site is its own workspace on SendBeam, so you can move one site, run it in parallel and move the next when you are ready. The three-site prices above assume all three are here; the bill is the pooled plan that fits whatever you have moved so far.

Who should stay on Buttondown

Stay on Buttondown if you write one newsletter in Markdown and value its API and privacy stance over everything else. Its base price at 1,000 subscribers is hard to beat.
