On my *nix machine I’m currently using NeoMutt & Aerc as MUA with different MTA/MRA. It suit my use case for reading lots of mailing list. Meanwhile on Android, currently using FairEmail. I was using K-9 Mail previously for over a decade.

Evolution, I wish I could use Thunderbird, but that crashes when signing mails with my Yubikey.

I’ve tried basically everything under the sun, and keep returning to Thunderbird. Thankfully they’ve fixed the endless amount of performance issues with it.

Everything else is either in a horrible state, abandoned, or paid spyware that used to be a free project originally

Thunderbird

Evolution currently. Previously Thunderbird. I wouldn’t mind a newer client but I am only interested in native apps talking to my email server over open standards.

The web browser.

I personally use Claws Mail.

Thunderbird’s not bad, but I usually use web stuff.

I have an existing iCloud e-mail that I haven’t had the time to switch off of. I then use G-Mail for school stuff - since I’ve signed away my soul to Google anyway, might as well use what they have to offer.

Maybe one day, I’ll start my own personal e-mail utopia, nut that day is not today.

To be honest, i still use Geary. It has a nice UI, and if you just read and write a small handful a month it still gets the job done.

Gnus, aerc, neomutt

I’m not a big email user, tried some of the clients multiple times and always return to web.

FairEmail

Geary on mobile, Thunderbird on desktop.

I like neomutt and kmail.

I use Mailspring. The only thing missing from Mailspring for me is seeing what folders my emails are in when I run a search. Otherwise, it’s the only non-CLI client I’ve found that let’s me use the keyboard to select multiple emails and move them to a folder, something I do in Gmail.

If anyone knows of others, let me know! I’ve tried Claws, Evolution, Geary, KMail, and Thunderbird in addition to Mutt and aerc in hopes of finding something to replace Gmail.
