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.

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

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.

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.
