I don’t need these “enterprise” features. I just need an e-mail. That being said, I do pay ~$5 per month (they charge PER user) for workspaces just for a hosted e-mail solution using my own domain (firstname@lastname.com).

One of these days, I’m going to self host it. Just need to figure out what’s the best way so my e-mails don’t get bounced back or get flagged as spam
