I chose Migadu because they seem to be genuinely helpful and are very affordable. I probably would have gone Proton but they don't support forwarding.
The downside is that downloading messages is fairly slow when you have 10-20k messages in your inbox. And the webmail is fairly primitive.
I never tried Fastmail.
I’ve been a Migadu customer for a few years. It’s a simple company with simple pricing, and I couldn’t be happier.
