RED ALERT! MailSpring Drafts are not syncing with Gmail accounts


The Drafts that I create on MailSpring client for my Gmail account doesn’t show up on the Gmail side and gets lost when I rebuild cache. This is unacceptable!

To Reproduce…

Steps to reproduce the behavior:

  1. Create a new draft on your mainspring client or edit an existing draft from Gmail
  2. Rebuild cache. It will disappear.


  • OS and Version: macOS Big Sur (11.6)
  • Installation Method: Installer
  • Mailspring Version: Latest (September 2021)

I can confirm the first part of your bug report: drafts created in Mailspring don’t get saved to the specified remote drafts folder. This is not actually a GMail issue - I don’t see drafts saved remotely on standard IMAP clients either.

However, I wonder why you’re rebuilding the cache often enough for it to be a problem. I’ve never done it in the 6 months I’ve been using Mailspring. And given that I’d expect “rebuilding the cache” to reset the local mail store to match what’s on the server, I don’t think what you report here is a bug. It’s just a consequence of the first bug, with drafts not being saved remotely.

The failure to sync drafts remotely is a major bug, though, IMO.
