Free, open source. It won't spy on you or track you. It may not be the easiest to set up, but given time to get it where you want it, it's pretty solid. Great IMAP implementation. Some mail services will need an app password to integrate with K-9. I have a dozen accounts configured - with the unified inbox, and been a happy user for over 10 years. And still my favorite to pull all my past emails together into a single view. Works with Gmail, Hotmail and Yahoo app passwords very well.

I have been using K9 for almost 10 years and loved it. But now the recent updates have made it almost unusable. Fetching takes forever. I can login to webmail faster, so what's the point. Also search is abysmal. I don't know what field the search uses but it doesn't find words that are clearly there. Then when I search the server, it only returns the subject line, no content. I have to wait for content to come in, then all of a sudden all the items disappear and i have to search again.

I tried... I can't. This used to be the best email client but this redesign is just terrible for multiple accounts. I've stuck with it for over a month and I've gotten used to a lot but can't deal without the "home screen" that shows my accounts. Besides UI, if an email fails to send on the first try it basically never will send and telling it to "send messages" does nothing" and to top that off there is no status so you don't know if it's even trying. I want the old K9 back!
