Interestingly, they use the Nodejs-based Haraka MTA instead of a more conservative choice like Postfix or Exim. I wonder what exact advantages they traded in more mature and certainly not much less performant software in for?
A very good and even cheaper alternative to this service I can recommend is mailbox.org, run by German IT service specialist Heinlein. They deliver a full OpenXchange setup (mail, calendar, contacts) with custom domain, 3 different mail aliases and additional + aliases and good privacy policy for 1€/month. They are very realiable (using a more conservative MTA, postfix), and the company is mature. They provide better value for money than migadu.com just by looking at it.
Hi, here Michael from Migadu. The reason we're using Haraka is that it's very fast, very flexible, and easily extendible. Furthermore, it's actually quite mature, version 2 was released in 2012 and now the're are about monthly releases. We are happy with it.
Not sure what your idea of "not much less performance" is. When craigslist switched from postfix to Haraka they went from 20 email servers down to 7 for the same load.

This depends on your use-case. For running a single account, yes. For one intended use-case of Migadu (managing multiple accounts across multiple domains), then no.
If I recall correctly, they have some laughable storage limits like 250 megabytes. Not a big fan of storing all my email locally and doing backups myself + no mobile search. So 1990ish, in my opinion.
2G storage for mailboxes. Search via IMAP sucks for pretty much all hosted IMAP I tried, only time it worked decently was when I was messing around via a self-hosted Dovecot and configured indexing manually.
