I’m on a Galaxy S10, and I really want a more privacy-respecting app than the included one. I tried FairEmail, and while it seems nice, it was extremely overwhelming and cluttered for me. Is there anything of similar quality that’s simpler to use interface-wise?
Yes, but K9 AFAIK only supports IMAP/SMTP, so a lot of SaaS email services (especially those hosted by Microsoft that are used by many companies) will not work with it.
In that case one is tied to the particular app anway. Or does FairEmail also support Active Directory or something alike?
I think it does, but not 100% sure.
