In general it works for me however I've got my secondary domain there with a very low traffic. I would't use Migadu for my personal email or something critical.

* good webmail
* catch-all email aliases
if the service is down (it was the case) there is no way to contact the team
no twiter, nothing. no public changelog
Great free e-mail server. Haven't seen anything better yet.
Free e-mail server, relatively easy setup
