What is Hide from archive?

On the Emails page under All Letters, each edition has a Hide from archive toggle that controls whether it appears on your public archive page.

Newsletters are visible in the archive by default. Toggle Hide from archive to remove an edition from the archive page — this works even after the newsletter has been published, in which case it disappears from the archive immediately.

This is handy when you’ve replaced a published edition with a corrected copy and want only the updated version showing publicly.

Long-time Letterhead users: in earlier versions of the composer, this feature was labeled Public and worked in the opposite direction — toggling right made an edition public, and the default was private.
