Geary on mobile, Thunderbird on desktop.

I have everything aggregated into Gmail, so I just use web and the mobile app. I'm looking at Proton but it doesn't have the "send as" feature for external SMTP services the Gmail does.

Evolution

I like neomutt and kmail.

mu4e because it's the best email client which runs in Emacs.

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.

I used to have lieer's gmi (read: mbsync with gmail tag syncing) paired with notmuch. It's good when it works, but it's annoying to need a service in the background.

I used to use Gnus, but Gnus is sometimes weirds out if your tag filters are too complex for it

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

Gnus in Emacs, configured to use autocrypt.

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.

Tuta (used to be called Tutanota), web and Android clients).

Because F++k Google.

I'm just using Gmail lol. I don't really do anything with email.
