I stuck with K9 because Fairmail has a cluttered UI. Yes, it's very fully featured, and I have nothing but respect for Marcel and it's a great option, but K9 is slightly easier to get started with for me.

I agree, I was using K9 until FairMail came out. It has all the features from K-9, it is open source and from very reliable developer which I trust more than Mozilla with its fishy additions to firefox (author of NetGuard (https://github.com/M66B/NetGuard ) which is the first software I install on any new phone. Firefox is the second, FairMail is the third).

I can only wish all the software would be of this quality, congrats M66B.

Agreed. In addition to its incredible reliability and capacity for customization, you can justifiably pretend that its name is actually Fairymail.

It's a one man job but you can feel he has put a lot of work and thought into it. The app has a lot of options but also a wizard that makes the set up easy.

I bought the premium version to support the developement. Support is over... email of course. He was very helpful when I asked about an issue I had with the app.

This sounds amazing. Is there something for the desktop? Maybe some self hosted client?

It's really weird that the only option seems to be thunderbird

Fairmail is simply the best way to use email on android. K9 comes in second definitely
