I just can’t find a decent email client that looks like it’s from the last 20 years. Geary and Evolution both appear to be pretty modern but something about using Gmail with a Yubikey just doesn’t work and neither of them will connect to my account. Both on Fedora and OpenSUSE. Thunderbird works but it’s so old fashioned and Betterbird doesn’t look much better. What’s everyone else using?
FairEmail is great! One of the best email clients I’ve ever used.
It started struggling a bit with a large mailbox though, so I switched to K9 Mail (which I’ve heard will eventually become Thunderbird for Android)
