Add more domains to your G Suite account

If you own other domains, you can add them to your G Suite account. You can also add a subdomain, for example, partners.kitbeat.com.

  

Kitbeat.com
Used to sign up for G Suite
(your primary domain)

+

Mixosteps.com
Another domain you own

When you add another domain, you can give existing users email addresses at the domain or create new users at the domain.

If you want to switch your primary domain to another domain, see these steps.


Step 1. Choose how to use your domain with G Suite

Decide whether to add your domain as a domain alias or as an additional domain.

Option 1: Give existing users an email address at the domain

Add the domain as a domain alias.

Each user get an email address at both your primary domain and domain alias
Each group (such as @info or @support) also gets an email address at the domain alias
Everyone can send and receive email from either address
All messages arrive in the user’s current G Suite inbox
No additional cost per user or group. Add up to 20 domain aliases.


Example: Ann signed up for G Suite with Kitbeat.comShe also owns Mixosteps.com and adds it as a domain alias. She and all her team automatically get email addresses at both domains. They manage all messages from their inbox at Kitbeat.com.  

   

ann@kitbeat.com     
ann@mixosteps.com    

matteo@kitbeat.com     
matteo@mixosteps.com    

Option 2: Create new users at the domain

If you have the legacy free edition of Google Apps, upgrade to G Suite to get this feature.

Add the domain as an additional domain.

Good for managing separate teams of users or businesses at different domains
Create user accounts for the additional domain
Each domain has a different set of users
Users have their own G Suite account, email address, and mailbox for their domain
Pay for each user account in the additional domain


Example: Ann manages two separate teams. Each has their own domain. She adds Mixosteps.com as an additional domain in G Suite.

Each team member has their own email address, mailbox, and user account for their domain. She manages all domains and users in her Admin console at Kitbeat.com (her primary domain).

     Kitbeat.com Team   Mixosteps.com Team
  ann@kitbeat.com
nguyen@kitbeat.com
lyle@kitbeat.com
  aditya@mixosteps.com
coraline@mixosteps.com
vincent@mixosteps.com
 

For information on restrictions, see Limitations with multiple domains.

Step 2. Add the domain alias or additional domain

  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console dashboard, go to Domains.

    To see Domains, you might have to click More controls at the bottom.

  3. Click Add/remove domains > Add a domain or a domain alias.
  4. Choose how to add the domain: 
    • Add a domain alias of primary-domain-name: This gives everyone in your primary domain an email address at the alias domain. Note: To add a domain alias to an additional domain, you must use the Domains Aliases API.
    • Add another domain: Adds a separate, additional domain with its own users.

      If you have the legacy free edition of Google Apps, upgrade to G Suite to get this feature.

  5. Enter the name of the domain or subdomain to add. You must own the domain name, and it can't be used with any other Google account. If the domain is already in use, you’ll get an error message. See troubleshooting tips.
  6. Click Continue and verify domain ownership
    Follow the instructions to verify that you own the domain. 
  7. Click Verify and continue to setup email delivery.
  8. Update the domain's MX records to set up Gmail.
  9. Click I have completed these steps.

For large organizations:  It can take more than 24 hours after verification for all users and groups to receive their alias email addresses.

Once your domain is active, see the Step 3 below to set up your users with their new email address or account. 

Step 3. Set up your users 

For a domain alias

Once your domain alias is active, messages sent to the domain alias address automatically arrive in users' inboxes. To send messages from their new address, users must add it to their Gmail account.

Share the sample message and instructions with your users. 

For an additional domain

Once your additional domain is active:

  1. Add each userto the domain in the Admin console.
  2. At the right of the @ sign, choose the user's domain from the dropdown list.

We recommend reviewing Limitations with multiple domains for help with managing users accounts.
