Nylas Mail (previously: Nylas N1) – an open-source mail client built on the modern web with Electron, React, and Flux. It was designed to be easy to extend, and many third-party plugins are available that add functionality to the client. It supports Gmail, Yahoo, Microsoft Exchange, and IMAP accounts.

The Nylas Mail user interface is styled using CSS, which means it’s easy to modify and extend. Nylas Mail comes stock with a few beautiful themes, and there are many more which have been built by community developers.

Nylas Mail was initially released and open-sourced in early 2015 and was maintained by Nylas until Spring 2017.

There are several forks of Nylas Mail that can be used instead, such as Mailspring or Nylas Mail Lives.

Mailspring – a new version of Nylas Mail maintained by one of the original authors. It replaces the JavaScript sync code in Nylas Mail with a new C++ sync engine based on Mailcore2. It uses roughly half the RAM and CPU of Nylas Mail and idles with almost zero “CPU Wakes”, which translates to great battery life. It also has an entirely revamped composer and other great new features.

Mailspring’s UI is open source (GPLv3) and written in JavaScript with Electron and React – it’s built on a plugin architecture and was designed to be easy to extend.

Mailspring’s sync engine is spawned by the Electron application and runs locally on your computer. It will be open-sourced in the future but is currently closed source. When you set up your development environment, Mailspring uses the latest version of the sync process we’ve shipped for your platform so you don’t need to pull sources or install its compile-time dependencies.

Mailspring comes packed with powerful features like Unified Inbox, Snooze, Send Later, Mail Rules, Templates and more.
