Mailspring – new version of Nylas Mail

Mailspring is an open source, cross-platform email client that is a development of the now discontinued Nylas Mail.

The Mailspring user interface is styled using CSS, which means it’s easy to modify and extend. Mailspring comes stock with a few beautiful themes.

It replaces the JavaScript sync code in Nylas Mail with a new C++ sync engine based on Mailcore2.

  • Multiple accounts (IMAP & Office 365).
  • Touch and gesture support.

  • Unified Inbox – supports all major mail providers—Gmail, iCloud, Office 365,, Yahoo!, and IMAP/SMTP.
  • Snooze emails – schedule messages so they are received at the ideal time.
  • Send Later.
  • Mail Rules.
  • Read receipts, link tracking, and more.
  • Search bar with powerful autocomplete that makes it easier to create advanced search queries. The software Indexes mail so you can use advanced, Gmail-style search queries and search message contents across all your connected accounts.
  • Templates.
  • Signature editor makes it easy to create and use custom signatures, even with images
  • Support for desktop notifications.
  • Activity tracking – know when someone has read your message.
