Migration guides: coming soon

We will publish these only after doing each migration ourselves on test accounts. Until then, there is nothing here, on purpose.

1. Substack → beehiiv: what breaks when you move
   Planned scope: Paid subscribers and Stripe, custom domain, SEO redirects off substack.com, comments and archives.
2. Substack → Kit: what breaks when you move
   Planned scope: Paid subscriptions, importing your archive, landing pages and automations.
3. Mailchimp → Kit: what breaks when you move
   Planned scope: Tags vs groups, automations, forms and sender reputation.

Meanwhile, the cost calculator shows what a move would change in your monthly bill.
