I’m contemplating taking control of my email by moving away from mainstream providers like Gmail or Outlook. What self-hosted email services have you tried, and which ones do you find most reliable and user-friendly? Are there any challenges or advantages you’ve encountered in making the switch?
To “take control of your email” I recommend buying your own domain, but not self-hosting.
Having your own domain will allow you to migrate from one email provider to the other, as you stop being locked in to them with their domain.
If you do not want to use Google or Microsoft, I recommend mailbox.org (used this one for a long time, but had to change, because I wanted to send emails from my aliases). Tutanota is also good choice.
Protonmail is also there as one of the more popular alternatives to Microsoft and Google, but I find them too expensive.
Why am I not recommending self-hosting email on self-hosting reddit? Unlike other services, which you can host at your home (which simplifies a lot of stuff and allow you to avoid subscription), you pretty much need VPS for selfhosting email. If your needs are simple, both mailbox.org and tutanota will cover your email needs for 3 euro per month. You don’t have to think about security, spam, email delivery, building trust with other email providers. It’s their responsibility, not yours. Good luck doing it cheaper on VPS.
I personally use M365 business basic, it’s very reliable but exchange online might not be user friendly. However price to value ratio is just unbeatable.
