I have been using mailbox’s light (1€/month) tier, which doesn’t include the calendar, so I can’t really tell you about its quality.
What I can tell you though, is that it has worked great with K-9 and Geary and everyone I have emailed has recieved it and it hasn’t gone to any spam folders or such.
