Hey folks! I’m the lead maintainer of the Mailspring email client (formerly Nylas Mail). Over the last few weeks we’ve been putting together a snap release and working through a few configuration and sandboxing issues (couldn’t make ourselves the default client anymore, etc.) Now that snapd 2.29.3 is out, the last known issue has been fixed!

If anyone has some spare cycles and is interested in trying a new mail client (or already using Mailspring!) grab the snap and give it a spin via snap install mailspring ! If you run into any issues, please post them here. We’ll be directing folks to the snap release instead of the dep / rpm packages in the next update cycle providing everything goes well. I’m really excited to be moving to snapcraft because it means Linux folks are finally getting autoupdate alongside our Mac and Windows users.

Note that in order to use Mailspring you’ll need to create a “Mailspring ID”, but the app doesn’t send your email passwords or credentials to the cloud—all email sync is done locally on your computer. It just syncs snooze dates and other metadata using the Mailspring ID, since those features can’t be built on IMAP alone.
