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).

Great email service with novel features I have been using Fastmail for such a long time now that I can’t even remember when I first signed up. It must be over a decade, now. It’s a great email service, with some nifty features, on top of the “basics” like notes, file storage, calendar, etc. Lately, they’ve partnered with 1Password to support “masked emails” so that when signing up online you can automatically create an email alias, so if you get lots of spam at that address, you can just disable it. It’s a neat usability enhancement to their email aliases features which I look forward to trying out.

Happy private and company users for… Happy private and company users for years. Sometimes, you really get what you paid for, I am honestly and genuinely happy with FastMail, their web app (its simplicity and speed), search speed too, their stability and reliability, the multitude of settings, aliases and multiple emails... There's nothing bad I could come up with. As far as I remember, it's also an independent private company (not owned by companies, which is a plus, not a fan of giant companies creeping in and starting to control everything). Really, keep it up as until now. Only good words.

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.

More than a decade, 0 complaints, perfection. Been a customer for more than a decade, paying customer since 5 years+ (student, so rarely use any premium services). It always works, it's fast, it's not creepy like *mail. There's no service around that has better features than fastmail, and they keep adding good stuff (masked emails). The app is fast, low in resource usage, and just plain reliable. Calendar integration is equally reliable. Support is courteous, fast, and complete (and human). You just can't go wrong with it.
