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’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.
Thunderbird is the usual recommendation for an email client. So try that
I’ve been using Betterbird for a while and I like it. It’s based on Thunderbird.
If your into Linux and a decent admin. Nothing is better than neomutt. Add not much.
Filtering and searching is faster than Google on gigs of mail.
It will take a long time to configure it well. But it’s worth it. I rarely change the config.
I have been using Linux since 1992.
I can’t wait to poke around neomutt when I set up my computer
You can use on windows or vm
At the time of posting, my most powerful computing device was my phone lol
Evolution is really great. I was able to make Kmail work, so because it integrates best into Plasma, I am using that. But setting it up was not a fun experience.
Try Betterbird.
