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.

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.

We have been using paid Fastmail for 15… We have been using paid Fastmail for 15 years and free prior. Never in your face. New features are timely and useful. Private. I make use of multi alias emails for various roles. And for spam minimisation whereby when purchasing or subscribing, if any later spam emails to that address I can just delete the alias and create another.

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.
