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

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.

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.

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.

Amazing service justifying the price I've been using FastMail Standard plan with my own domain for few months. I'm amazed how the service is working. It is fast, reliable, works great on iOS devices. Webmail interface is great - intuitive, has keyboard shortcuts. I moved mine and my wife's primary email accounts to FastMail and purchased three years plan. When I send tickets to support I receive an answer within 24h. I highly recommend it. I admit it is not cheap, but definately worth the money.
