1. Add your domain to Fastmail
We have a setup guide to help you get your domain working as quickly and easily as possible.
After you have purchased your domain from iwantmyname, log in to Fastmail and go to the Settings → Domains screen.
Add your domain(s) (e.g.
mydomain.com). Using the Add Domain button brings up the new domain screen. Type your domain into the text box.
If your domain has been purchased from iwantmyname, we will display this on the next screen. You can also choose iwantmyname from our list of supported registrars.
Follow the wizard to add your email addresses to Fastmail. The wizard will ask you if you have a website at your domain. Answer Yes or No.
Please note: The domain setup wizard is not currently available to users on legacy plans. If you are on a legacy plan, you will need to add users or aliases manually in order to receive mail at your custom domain.
