Last updated July 06, 2026 19:40

Update the domain associated with your business email address.

Your primary domain is the domain that appears after the @ in your email address. For example, @mysite.com. If you registered a new domain, update your primary Google Workspace domain.

To update your primary Google Workspace domain:

1. Log in to your Google Admin console.
2. Navigate to your domain management settings and choose a new primary domain. If you have issues changing your primary Google Workspace domain, contact Google for help.

What happens to my old email address?

After changing your primary domain, people may still try to email or share files with your old email address. To ensure you don’t miss any important messages or sharing notifications, set up an alias or a secondary domain:

• Add your old domain as a domain alias - Send and receive email at your new primary domain and old domain at no additional cost.
• Keep your old domain as a secondary domain (default) - Add a separate set of users to the secondary domain. Users have their own email address at the secondary domain, and you pay for each account.

Remove the old domain

If you don't want to use the original primary domain, remove it from your Google Workspace account.
