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.

This is top 1 on bad mail providers This is top 1 of bad mail providers. They read everything in your mailbox. And stolen data in your mail if it is important. I don't understand why fastmail can alive today? The app and mail server are bad, often got technical issue.

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.

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.

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).
