Which hoster do you use?
I had heard only good things about masto.host but they had closed their subscriptions, so I signed up with both Ossrox and Weingärtner IT to give both a try.
I have not decided yet which one to keep because they were both flawless so far. I ordered from both at almost the same time and they both activated my accounts almost at the same time about a day later.
Main instance I use currently is the Ossrox one, but that is just coincidence.
I'm not in any way affiliated with any of those companies and don't know anyone working there personally.
Just use any of the hosters, set up the DNS record and be done. It's pretty similar to hosted e-mail under your own domain and even cheaper than a Twitter Blue subscription.
