Adding Fastmail nameservers to

Setting your nameservers to work with Fastmail is an easy way to make sure your domain has all the correct DNS entries and your mail will work correctly.

Changing your nameservers is the best option if you do not have a website for your domain hosted with another service, or you would like to host both your mail and a website with Fastmail.

We provide a control panel for full customization of your DNS records should you need it. Our nameservers are fast, reliable and secure. Our web interface for managing DNS is simple, but still powerful enough to allow any number of records of any type.

There's just two simple steps to set up your domain:

  1. Add your domain
  2. Edit your nameservers in

1. Add your domain
