If you are looking to delete your custom domain, you can do so by following the steps below:
1. From your Moxi account, navigate to "website" or "my website."
2. On the left-hand side of the website admin tool, hover over "settings" and click "personal domain."
3. Set your default domain as primary.
Once your default domain has been set as primary, the "remove" button will appear next to your custom domain - then, you can click "remove" to successfully remove your custom domain.
