Mailspring 1.2.2


MailSpring is an open source email client application which support Windows, MacOSX and Linux. Mailspring supports all IMAP providers, including Gmail, Office 365 and iCloud. It sports features such as an unified inbox, snoozing, reminders, templates, offline search, and support for Gmail labels. Mailspring is free for Mac, Windows, and Linux. However, if you use features like Snooze, Send Later, Send Reminders and Read Receipts often, you'll need to purchase a subscription to Mailspring Pro within the app. Mailspring Pro costs $8/mo and helps support the development of Mailspring.

About Mailspring ID

When you install Mailspring for the first time, you'll need to create a Mailspring ID. Your Mailspring ID is separate from your email account(s) and you can use any email address or password you'd like. Mailspring does not store your email passwords in the cloud. It syncs only the minimal amount of data required to power features like snooze, send later, etc., and uses a hashing mechanism to identify emails and associate it's metadata across installs.

If you create a Mailspring ID and later decide you don't want one, you can sign in to the Mailspring ID dashboard ( at any time and permanently delete your account and all data associated with it.

Mailspring 1.2.2 fixes:

  • In the Linux Snapcraft release, app indicator compatibility has been improved by coercing XDG_CURRENT_DESKTOP to Unity (Thanks Martin Wimpress at Canonical!)
  • On Linux, clicking on the system tray toggles the visibility of Mailspring's windows instead of always showing them. #650
  • On macOS, Mailspring asks if it can move itself to Applications and handles the new app translocation rules in High Sierra correctly.
  • Drafts now allow file attachments up to 25MB in size, and the error message has been corrected. #854
  • When linking email accounts, the IMAP/SMTP host fields correctly ignore whitespace to avoid connection errors. #876
  • Mailspring's sync process no longer crashes when the snooze / reminder actions of more than 200 threads need to be processed at once.
  • Mailspring now correctly auto-links email addresses in the composer into mailto: links #814
  • Searching by subject:xxx now works, thanks to fixes to the mailsync indexer. #860
