I've recently decided to change email providers and so I had to change quite a few things. I went from encrypted mail (Tutanota) with their own client to a plain mail / standards-compliant mail provider (Migadu) after looking at many providers. (I'll probably make a blog post about it in the near future.)
So I'm just wondering.
What email provider do you use?
What clients do you use?
How do you treat your email?
Anything else you want to share in relation with this?
