A new beginning for Nylas Mail.

Who is Mailspring?

Hi there! My name is Ben Gotow, and I'm one of the original authors of Nylas Mail. My company, Foundry 376, is re-launching Nylas Mail because I believe it can be—and should have been—the best new mail client in a decade.

We're spinning up new infrastructure, re-writing huge parts of the codebase, and committed to offering the same free version and paid Pro features that made Nylas Mail the best mail client for work.

What's better about Mailspring?

  • The JavaScript sync engine has been replaced with a new C++ core built on the same framework that powers Sparrow, Airmail, and more. Mailspring uses ~50% less RAM, syncs mail faster, and won't hurt your battery.
  • Heavy dependencies have been removed and the package manager has been re-written for speed. Mailspring launches in a second.
  • This is just the beginning. Mailspring isn't VC funded and doesn't need to make millions to succeed. Just a thousand paid subscriptions will make Mailspring a stable business and we have big ideas for the future of email.
