FAQ | Fastmail alternatives

What is better than Fastmail?

Is Fastmail worth it?

Fastmail can be worth it for users who value privacy and a clean, ad-free interface. It offers robust features like spam protection and calendar integration. However, it’s a paid service, so its value would depend on whether these features align with a user’s specific needs.

Does Fastmail still exist?

Yes, as of my knowledge cutoff in September 2021, Fastmail is still in operation. It continues to provide email services to users worldwide.

Is Fastmail better than Gmail?

Whether Fastmail is better than Gmail depends on what you’re looking for in an email service.
