THE SUBSTACK EXIT CHECKLIST
Move off the platform without dropping a single name. Pack the list, rebuild
the archive, re-point the world, hand back the keys. Slow is correct.


THE FRAME
This isn't a divorce. It's moving out of an apartment you never owned. Pack
your stuff, change your address, hand the keys back. The only thing that can
go wrong is forgetting a box. The box you can't forget is your list.


KNOW WHAT YOU ACTUALLY OWN BEFORE YOU PACK
  [ ] My subscribers are mine. The platform lets me export them.
  [ ] My URL is theirs. Every link I shared points at their building.
  [ ] The recommendation network only works inside their walls.
  [ ] My paid billing relationship does NOT export clean. A list of who pays
      comes out fine. The live charge stays trapped behind their checkout.


STEP 1, EXPORT THE LIST BEFORE YOU TOUCH ANYTHING
The list is the business. Treat the file like cash.

  [ ] Exported subscribers to a CSV (Settings > Subscribers > Export).
  [ ] Downloaded it once to my machine.
  [ ] Downloaded it AGAIN somewhere else: a second drive, a thumb drive, a
      backed-up folder. Anywhere that isn't the same hard drive as the first.
  [ ] Opened the file and confirmed it's live email addresses in the rows,
      not an empty header line pretending to be data.


STEP 2, DECIDE WHERE EMAIL LIVES NOW
You need a thing that holds a list and sends a newsletter. Low bar. Ignore
the holy war over which tool is correct.

  [ ] Picked ONE of two honest shapes:
        - Self-hosted: free list software on the same cheap box as the rest
          of the operation, pointed at a sending service for delivery.
        - Hosted: an email service that holds the list and sends for you,
          cheap at small scale, and lets you leave on the same CSV trick.
  [ ] Underneath either one, picked a transactional email service to
      physically haul the mail. (I am NOT running my own mail server.)
  [ ] Did NOT jump into another all-in-one platform that wants to be my
      homepage and my store and my church.
  [ ] Imported the CSV. Free subscribers landed as a flat list of emails.


STEP 3, REBUILD THE ARCHIVE ON GROUND YOU OWN
Your posts are words you wrote. Get them out and stand them up as real pages
on your own domain.

  [ ] Pulled the post export (HTML plus images). If it choked, pulled the
      whole catalog from the RSS feed instead.
  [ ] Landed them as plain files built by my static site generator into my
      own design, no database, nothing to patch.
  [ ] Kept the post slugs where I could, so old links don't dead-end and the
      old search traffic survives the move.


STEP 4, RE-POINT THE WORLD, DON'T JUST VANISH
A name in a file is worthless if the person never hears from you again. You
have to bridge them across. Order is the whole trick.

  [ ] Sent the goodbye-and-hello from the OLD platform first, while I still
      held the megaphone: I'm moving, here's the new home, check spam for the
      next issue.
  [ ] Fired the same message from the NEW sender immediately, so the new
      inbox shakes hands with my new face and won't junk me.
  [ ] Left the old place standing as a signpost: pointed it at the new home,
      pinned the moving post, rewrote the about page. Did NOT nuke it day one.
  [ ] Hunted down my own backlinks by hand: social bios, email signature, old
      posts, show notes, guest pieces. Swapped every one.


THE PAID CATCH, HANDLED, AND SLOW IS CORRECT
You can't export a live billing relationship. You re-earn it.

  [ ] Stood up my own payment rail and checkout.
  [ ] Emailed paid members straight: here's the new home, here's the link to
      keep your membership, founders get a better rate, no rush.
  [ ] Killed the old billing ONLY after handing people a real window to move.
      Yanking it early picks the pockets of my best supporters.

Everything else you leave behind is rented furniture. The list rides home in
a file. The address only changes for real when you change it everywhere
yourself, one entry at a time.
