Thunderbird, Evolution and Geary are the three most well-known email client is open source, available for desktop users with Linux. Recently launched a new app that hopefully will join the above three, the app that promises to create a new feeling from the email.
As a web browser or a modern text editor that N1 can be modified and extended by using extensions. The plugin architecture allows developers of any level to easily add new capabilities – from adding buttons to the window writing a letter to the new side bars or even a new UI!
Not everyone wants to extend the capabilities of the application; a key part of the app, apparently, has everything you need for the average user and the clear appearance allows the user to focus on the app, and directly on e-mail.
N1 supports popular web mail services, including Gmail, Yahoo!, Hotmail and Yandex.Mail. But, unlike traditional desktop e-mail application, N1 is not connected to web services using standard IMAP or SMTP.
Default N1 uses Nylas API, and an engine sync that occurs through its own cloud infrastructure Nylas. Actually, it means that you receive all mail is held and stored on the server Nylas.
It is clear that it is not for everyone. Doubting users can run their own local version of the sync engine and API service to keep N1 isolated.
Modern API and Sync Engine from Nylas work with many existing email providers. This allows the application to forget about "the complexity of old protocols like IMAP and MIME".
N1 – platform with binaries available for installation on Mac and Linux (Windows is expected soon).
The downside is that the app still can only be obtained by invite.
