Are Murena's email services any good?

Since Autistici/Inventati was sanctioned by the U.S. government as a "global terrorist organisation", I'm looking for alternatives.

The company is based in France and their services are in Finland (so GDPR!), they have a free plan + IMAP support too, but there doesn't seem to be much discussion of it compared to other email providers, like mailbox, Fastmail, or Posteo. Does Murena have a good track record with their email?
