I'm setting up my Nextcloud server and am at the point of needing to connect an email server. I'm not interested in selfhosting an email server (not yet anyway), and I don't particularly like Proton as my current email provider (which was what I migrated to when de-Googling my life).

What email providers do y'all like that aren't run by shady tech bros and are easy to integrate with your other selfhosted services?
