I have self hosted my email for about twenty years; fr about ten or fifteen I just forwarded everything to Gmail but had to revert to local ( started with local mail in emacs, but switched to imapd to solve the airplane ticket in the airport issue) because so much important stuff was marked as spam. Like in the middle of a conversation between me and on other person their reply to my email (which I always bcc:ed ack to myself) would disappear. Self hosted is much better. It took few iteration to get spf etc working.

How do you guarantee uptime for yourself?

Just check email from time to time. Major outages have been my DNS registrar got sold and another time secondary DNS company got sold and I missed the emails. Postfix and Imapd are run by systemd or init.d. I think I filled the root filesystem once. I also pay for backup MX forwarding so brief (few days) outages don’t cause mail loss.
