Add multiple domains or domain aliases
If you own another domain, you can add it to your G Suite or Cloud Identity account.
You can add a domain (or subdomain) as:
- A domain alias: You and your users get email addresses at the domain. Send email and receive email at your primary domain and domain alias. No additional cost.
- An additional domain: Create user accounts at this domain (also called a secondary domain). If you have G Suite legacy free edition, you can only add a domain alias not an additional domain.
Option 1: Give users an email address at the domain
Add the domain as a domain alias.
|✓||Each user gets an email address at both your primary domain and domain alias|
|✓||Each mailing 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 primary inbox|
|✓||No additional cost per user or group. Add up to 20 domain aliases.|
Example: You signed up for G Suite with your-company.net (your primary domain). You own the domain other-company.com and add it as a domain alias.
You and your team automatically get email addresses at both domains.
For information on restrictions, go to Limitations with multiple domains.
Option 2: Create new users at the domain
Add the domain as an additional (secondary) 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 get a G Suite account, email address, and mailbox for their domain|
|✓||Pay for each user account in the additional domain|
Example: You manage two separate teams that have their own domain. You add other-company.com as a secondary domain.
Each team member has their own email address, mailbox, and user account for their domain. You manage all domains and users in your Admin console at your primary domain
STEP 2. Add the domain alias or additional domain
From the Admin console Home page, go to Domains Manage domains.
If you don't see Manage domains on the Home page, at the bottom, click More controls.
- Click Add a domain or a domain alias.
- Choose how to add the domain:
- Add a domain alias of primary-domain-name: Everyone in your primary domain gets an email address at the alias domain. (To add a domain alias to secondary domain, use the Domains Aliases API.)
- Add another domain: Adds a separate, secondary domain with its own users.
If you have the legacy free edition of G Suite, upgrade to G Suite Basic to get this feature.
- Enter the name of the domain or subdomain. 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. Check troubleshooting tips.
- Click Continue and verify domain ownership
Follow the instructions to verify that you own the domain. If you need assistance, contact your domain host (typically where you purchased your domain) or G Suite Support.
- Click Verify and continue to setup email delivery.
- Update the domain's MX records to set up Gmail (G Suite only) for your added domain.
- Click I have completed these steps.
Once your domain is active, go to Step 3 to set up your users with their new email address or account.
STEP 3. Start using your domain
Use your domain alias
Messages sent to your alias address automatically arrive in your inbox. To test, send a message from another account (not your G Suite account) to your new alias.
Send messages from your alias address
Add your alias address to your Gmail account.
On your computer, open Gmail.
- In the top right, click Settings Settings.
- Click the Accounts and Import or Accounts tab.
- In the "Send mail as" section, click Add another email address.
- Enter your name and your alias address.
- Check the Treat as an alias box.
- Click Next Step and follow the confirmation steps.
When you send a message in Gmail, click From to select an address.
How your primary email address and alias work together
- You sign in your G Suite account with your email address.
- You can create documents and files only with your email address
- People can share files with either your email address or alias.
- Google Calendar invites and sharing invites are sent only from your email address.
Tip: Share the sample message and instructions with your G Suite users.
Use your additional domain
Once your additional domain is active:
- Add each user to the domain in the Admin console.
- At the right of the @ sign, click the Down arrow and select the user's domain.
