there is a lot of mail client, tbh, you just not know them. Mailbird is a popular example you've skipped.

for my desires - all of them sucks anyway, not providing basic features that are needed and bloating the client with thing almost-nobody-need

Another is The Bat!. I've personally been using this email client for PC for 10 years now. https://www.ritlabs.com/en/

It has extremely powerful filtering, multiple inboxes for all my accounts (I prefer to deal with them separately rather than the unified inbox trend), IMAP and recently redone outlook.com/Exchange pipeline, can encrypt local store, and it's very customizable (can have it do threading/conversation for example). Reminds me of the old Opera in this regard.

The UI is a bit dated imo as it has stayed true to it's same look the whole time I've used it and skipping the modern trend of Outlook-like email client looks, but this to me is part of it's appeal. Once you get used to it.

That's pretty much the tagline of mutt[0].

> All mail clients suck. This one just sucks less.

I've become really fond of notmuch[1]. It's basically a mail database and library with really fast search, tags, and native support for threads. Numerous front-ends exists[2]; I use the bundled emacs client, but have wanted to try out nevermore[3] (it did not work well with Evil last I checked).
