I'm really enjoying Fastmail Setting up a family domain with four users was pretty straight-forward as was importing email from my previous server. The apps work well and features such as snoozing messages, masking (temporary addresses), aliases, etc are really useful. You get lots of storage for the price. If I had any criticism it would be that the UI needs optimisation in places but these are minor niggles, it's still five stars.

We will not use anything else. We have been using fastmail for our company for a long time now. The entire company's email history was imported so now there is close to 300G of emails. Fastmail has proven invaluable because 1. Very good search of large quantities of emails 2. Shared folders allow excellent collaboration 3. Fast 4. Flawless interfacing with thunderbird, outlook, mobile devices 5. Very cool email alias feature 6. Most economical hosting of large quantities of emails 7. SPAM filtering is very good

happy user! Moved from a self-managed email server to Fastmail 20 years ago. Zero regrets. Best email service. Very happy to pay a reasonable price for a rock solid service with no surprise, and a respect for my privacy. Strong authentication with a hardware key option. I only use for emails, not used their calendar or contact services. For these I still find the Apple apps easier and more intuitive.

Very happy with Fastmail I've used Fastmail for about two years, using my own domain there. It has worked perfectly for me. For that reason, I happily can't comment on their responsiveness to service requests. I've also had zero problems with spam. I use the iOS app and my desktop, via Thunderbird. In my opinion, the cost is reasonable for the level of service, and the comfort of not wondering what invisible way the provider is building a dossier on me.

It just works well It just works well. No drama, no uncalled for features, no downtimes, no BS. When I need support, they are helpful and fix stuff. I'm happily paying and not worrying at least about my e-mail (can't say the same about other providers of online services).
