I still use the web interface for each email provider like gmail, outlook, etc
Evolution.
Thunderbird since forever. Before that, Seamonkey and the Mozilla suite.
There are some changes I didn’t like over the years like the tabbed interface for everything, but nothing else ever came along that worked as well and was multi-platform.
Betterbird
claws ☞ https://www.claws-mail.org/
Any halfway decent desktop email client will do the job—people have already listed several. I use claws-mail, but getting it to work with GMail involves the computer equivalent of doing a triple backflip through a hoop, so you may want to go with something more common.
seamonkey and thunderbird are both good
Good ol Thunderbird
aerc+mbsync+notmuch
If you want a GUI, I was using Evolution before aerc and I was happy with it. I just prefer keyboard navigation which naturally is well supported by any TUI application.
I use Thunderbird.
Sometimes you just cant beat the classics.
Especially when the classic Thunderbird was just overhauled with modern UI
(Which you can disable, luckily. I still use the classic layout with the table of emails on top and the selected email below)
Thunderbird
Thunderbird and neomutt.
I like evolution a lot
I use AERC. TUI that is just so painfully easy to use. integrates with whatever editor you use like vim or emacs or whatever. Account setup is a breeze via a config file thus making it easy to backup. I have it in my nix config so whenever I take my nixos anywhere or reinstall it I instantly have my email ready to go.
aercÞis is þe way.
I use msync and notmuch, to provide Google-like tagging and searching, and to keep a local email cache so it’s faster, but aerc supports boþ notmuch and IMAP, so you get boþ.
Also Thunderbird, but specifically the Betterbird fork.
It works well, its fast, its lightweight (like 100-200MB of RAM), and has lots of features.
I also have my calendar in it.
