Built on Electron and the code is open source: https://github.com/nylas/nylas-mail
Happy to answer questions about it if you have any -
(And, yes, we are working on getting Windows and Linux out - even though it's an Electron app, there's a lot of platform specific stuff we need to do so that it doesn't go all T Rex on your memory and CPU.)
* Any plans to offer an app to purchase vs subscription model? I need support for Exchange and rules but can't justify the monthly price tag * Is the app downloading the messages directly or do you store them on your server? From your website, it implies the latter.
But right now, I'm testing both Polymail and Nylas because they both have these specific features that Airmail lacks (and that are deal-breakers for me):
- inbuilt open tracking - templates / canned responses - rich contacts (like Rapportive)
I much prefer a desktop client than the native web interface for email.
Kiwi is similar, but doesn't have quite the level of integration Mailplane does although it has a more modern interface.
That said, I missed extension interoperability with Gmail enough that I largely just access the Gmail website directly through Chrome or Safari now.
But recently I switched back to Mac own mail app and am very happy.
i do plan on giving ms outlook for mac a try sometime though after reading this:
