Ranked in these QuestionsQuestion Ranking
Pro Great design
Simple, easy to use, easy to learn user interface.
Pro Open Source
You can change it, customize it, and make plugins for it.
Currently there are plugins for GitHub integration, Templates, and Translation, and the potential for many more to come. It's built on top of Chromium so making plugins for it will not only be easy for Chrome app and extension developers, but it means that it has the potential to use Chrome plugins, too.
Pro Dynamic, secure, private
You can use Nylas' servers, or run your own mail server on your own computer.
Pro Works with Exchange accounts
N1 is one of the few 10 Windows Desktop Clients to offer support for a business Exchange email account (the Windows Native Client is one of the few alternatives that also work). It seems that this niche is really dominated by Outlook, and few solutions are available that prioritize it.
Pro Pretty Good Privacy or PGP built-in
Pro Gorgeous and intuitive
Pro No personal data stored on servers
No access tokens, passwords, attachments or email itself is stored on Canary servers.
Pro Local email database is encrypted on disk
Canary stores your local email database encrypted.
Con Some features require a monthly subscription
Con A lot of RAM memory used
This email client uses a lot of RAM (random access memory) - actually using more than Chrome (albeit with a lot of tabs open).
Super slow to sync. not really supported anymore as they're focusing on their API.
Con Poor text editing capabilities
The cursor is laggy so you're better off using keyboard shortcuts.
Con Windows moves randomly
When you create a new email, the new windows is often misplaced so that you have to move it to reach the "Send" button.
Con Poor handling of new emails
You sometimes need to wait very long before your email actually gets delivered.
Con Show NO show
It'll show I have new email as a counter but I'm not able to view them.
