I have been using KDE for a while, while I like many features I am looking for suggestions to the default email client:
Kmail - completely unusable for me and the only one which could maybe be integrated with kontacts, it could not receive mails from IMAP or pop or would receive only sometimes
Geary - good but too minimal, I need at least some kind of contact list and mailing lists feature, maybe this integrates with gnome contacts? I couldn’t find anything in settings
I used Claws Mail at some point in the past. Now notmuch+Emacs.
evolution
I landed on Claws Mail myself. It does look a bit dated, but the UI is functional and the client works. I’m content with it.
At first i thought, wow, cool they’re still developing that? Doing a release or two a year, i see.
I used to use it long ago, and was pretty happy with it.
But looking closer now, what is going on with security there?! Sorry to be the bearer of probably bad news, but... 😬
The only three CVEs in their changelog are from 2007, 2010, and 2014, and none are specific to claws.
Does that mean they haven’t had any exploitable bugs? That seems extremely unlikely for a program written in C with the complexity that being an email client requires.
All of the recent changelog entries which sound like possibly-security-relevant bugs have seven-digit numbers prefixed with “CID”, whereas the other bugs have four-digit bug numbers corresponding to entries in their bugzilla.
After a few minutes of searching, I have failed to figure out what “CID” means, or indeed to find any reference to these numbers outside of claws commit messages and release announcements. In any case, from the types of bugs which have these numbers instead of bugzilla entries, it seems to be the designation they are using for security bugs.
The effect of failing to register CVEs and issue security advisories is that downstream distributors of claws (such as the Linux distributions which the project’s website recommends installing it from) do not patch these issues.
For instance, claws is included in Debian stable and three currently-supported LTS releases of Ubuntu - which are places where users could be receiving security updates if the project registered CVEs, but are not since they don’t.
Even if you get claws from a rolling release distro, or build the latest release yourself, it looks like you’d still be lagging substantially on likely-security-relevant updates: there have actually been numerous commits containing CID numbers in the month since the last release.
If the claws developers happen to read this: thanks for writing free software, but: please update your FAQ to explain these CID numbers, and start issuing security advisories and/or registering CVEs when appropriate so that your distributors will ship security updates to your users!
I have used Evolution in the past. It was very Outlook like and did a decent job talking to Exchange. Now days i just use the web interface.
Claws mail
I am A big fan of Vivaldi and its built-in email client ^^ Works like a charm for me.

You may also find some ideas here or there.
I personaly use the power of neomutt and notmuch, but it’s not a GUI option if that’s what you’re looking for.
Every time I look around for a new mail client I come back to thunderbird. Nothing else ticks all the boxes
IMHO, you should consider doing more troubleshooting on Kmail. I’ve never used it personally, but from my understanding, it’s a stable program and shouldn’t have problems doing the basics of email, like you’re reporting.
The problem of kmail is the underlying subsystem that is evertything other than stable.
What mailing list features do you need?
90% of the time I use web interfaces, but I often have spotty connectivity while boondocking. So I need a client that can get/send gmail POP3 in narrow windows of connectivity.
I started with thunderbird but something (can’t remember what) wasn’t working well. Ended up with Evolution. It also syncs well to google calendar and google tasks.
Try Betterbird.
That is the correct answer
Damn these guys are very passionate about how shitty thunderbird is
If you arena opposed to GNOME, you add your online accounts and it integrates them into evolution mail, calendar and contacts. And also Gdrive becomes a mounted folder if you add Google account.
No I actually prefer GNOME, but have to use KDE because I need specific features (kiosk mode), but yes I feel like Gnome is so much better integrated with its defaults apps!
Mailspring
I’ve used Thunderbird since forever as my go-to client, I used mutt as well for a while and that met my needs pretty well.
