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.

The spam filtering is very poor. The spam filtering is very poor, and they make the most absurd suggestions to try and improve it. They want me to create a folder to mark emails as 'non-spam'. What? If I don't move an email from the inbox to the spam folder, shouldn't that be indication enough that it is NOT spam? Speaking of which, I also receive Fastmail newsletters even though I'm opted out. This makes it spam, doesn't it? I will be moving to another provider.

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.

Awful company that does not comply with… Awful company that does not comply with data laws - they withhold your data and their support team of Quinn and Tyler try to fob you off when you want to access private information. Had to involve solicitors and they have tried to ignore our solicitors also. Unethical company DO NOT USE or your data will disappear also. Legal Team and Data privacy team do not exist so be warned!!!

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
