N1 is an open source desktop email client by Nylas known for its emphasis on user-contributed extensions.
N1 is an open source desktop email client. It is compatible with multiple Gmail, Yahoo, Microsoft Exchange, and IMAP accounts, and is cross-platform on Linux, OS X, and Windows. The application accommodates user-written plugins. It has several layout styles in single or double panels, and has fullscreen and offline modes. By default, its mail sync functions are processed in a cloud owned by Nylas, the company responsible for the project. N1 added a unified inbox in February 2016 and PGP encryption support in June 2016
At the beginning of 2016, Macworld wrote that the software looked promising and had a better chance of enduring longer than past software—such as Sparrow and Mailbox—due to its open source license. The Next Web highly praised N1's extensions features and wrote that it could become for email what Google Chrome is to web browsing. N1 was the third most popular email desktop client among AppleInsider readers as of January 2016.
