I have a problem with price. $90 for about 20 personal emails per year and a bunch of useful newsletters?
Is there a $10 hosted mail that sends and receives reliably and doesn't sell my personal data on top of subscription (like AV companies)?
The support is first rate. I've seen their developers on Github helping to track down a synchronisation problem that could have either been with the open source tool, or Fastmail.
Turns out it was a Fastmail bug, and they promptly fixed it.
My recommendations for cheaper, more flexible and privacy respecting services are Posteo (no custom domains) and Mailbox (allows custom domains). See my comment above at https://news.ycombinator.com/item?id=14624624
