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?
I’m lazy - just gmail pinned in a tab on my browser on my Linux desktop, the browser is always open anyway. Default mail client on iOS/iPadOS.
I’ve used Thunderbird in the past. The redesign was nice but it’s still a bit cludgy to use somehow, compared to gmail web.
