Description:

MAILSPRING IS A NEW VERSION OF NYLAS MAIL MAINTAINED BY ONE OF THE
ORIGINAL AUTHORS. IT’S FASTER, LEANER, AND SHIPPING TODAY! 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 TypeScript with
Electron and React - it’s built on a plugin architecture and was
designed to be easy to extend. Check out CONTRIBUTING.md to get started!

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.




Features

Mailspring comes packed with powerful features like Unified Inbox,
Snooze, Send Later, Mail Rules, Templates and more. Mailspring Pro,
which you can unlock with a monthly subscription, adds even more
features for people who send a ton of email: link tracking, read
receipts, mailbox analytics, contact and company profiles. ALL OF THESE
FEATURES RUN IN THE CLIENT - MAILSPRING DOES NOT SEND YOUR EMAIL
CREDENTIALS TO THE CLOUD. For a full list of features, check out
getmailspring.com.


Download Mailspring

You can download compiled versions of Mailspring for Windows, Mac OS X,
and Linux (deb, rpm and snap) from https://getmailspring.com/download.


Contributing

Mailspring’s UI is entirely open-source and pull requests and
contributions are welcome! There are three ways to contribute: building
a plugin, building a theme, and submitting pull requests to the project
itself. When you’re getting started, you may want to join our public
slack so you can ask questions and learn from other people doing
development.

Building A Plugin

Plugins lie at the heart of Mailspring and give it its powerful
features. Building your own plugins allows you to integrate the app with
other tools, experiment with new workflows, and more. Follow the Getting
Started guide to write your first plugin in five minutes. To create your
own theme, go to our Theme Starter guide.

A plugin “store” like the Chrome Web Store is coming soon, and will make
it easy for other users to discover plugins you create.

Building a Theme

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, and there are many more which have been built by community
developers. To start creating a theme, clone the theme starter!

If you are updating an existing Nylas theme for Mailspring here is a
step by step tutorial. Notice: as part of the update process you will
probably need to import mailspring base variables.

Localizing / Translating

Mailspring 1.5.0 and above support localization. If you’re a fluent
speaker of another language, we’d love your help improving translations.
Check out the LOCALIZATION guide for more information.

Contributing to Mailspring Core

Pull requests are always welcome - check out CONTRIBUTING for more
information about setting up the development environment, running tests
locally, and submitting pull requests.
