Easy and reliable open source android email app, have been using this as a daily driver for the last couple of years and have no problems.
Works well with Gmail, Yahoo, and Yandex. Plan to use it with Protonmail too.
It has the nice feature of disabling all email notifications, just that this setting is per account and not global.
Works awesomely, until you need a subfolder in your Inbox (some email hosts insist), which K9 will not see at all. Unlike other apps, it seems K9 can only handle files OR subfolders, but not both.

I use it for a long time, the functionality is quite simple and global, just as it should, thanks!
K-9 Mail supports IMAP, POP3, and Web DAV accounts, but it does not support Microsoft Exchange accounts.

What keeps me from switching from Aqua Mail to K-9 Mail is their lack of a decent widget--the only one they have is for a Unified Inbox which I never use. Also no dark theme and no contact pictures on widget. I know that there are other 3rd party widgets out there for K-9 Mail, but inevitably they become abandonware or don't work very well in the first place.
