How to Create a Domain Alias in Google Workspace

A Domain Alias in Google Workspace allows users to receive emails from another domain while using the same Gmail mailbox. This feature is useful when a company owns multiple domains but wants to manage email accounts centrally.

For example, if a company owns:

company.com
company.in
company.net

Users can receive emails from all domains using a single mailbox.

Example:

user@company.com
user@company.in
user@company.net

All emails will arrive in the same Gmail inbox.

Domain Alias vs Secondary Domain

Understanding the difference is important.

Domain Alias

• Uses the same user accounts

• Emails automatically work for both domains

• No need to create separate users

Secondary Domain

• Requires separate user accounts

• Each user must be created manually

Domain alias is simpler when you want the same usernames across domains.

Steps to Add a Domain Alias

Follow these steps to configure a domain alias.

Step 1 – Login to Admin Console

Open:

https://admin.google.com

Login with a Super Administrator account.

Step 2 – Navigate to Domains

Go to:

Admin Console → Account → Domains

Step 3 – Add Domain Alias

Click:

Add a Domain Alias

Enter the new domain name.

Example:

company.in

Step 4 – Verify Domain Ownership

Google will ask you to verify ownership using a DNS TXT record.

Example:

google-site-verification=xxxxxxxx

Add this record to your domain DNS.

Step 5 – Update MX Records

Configure the MX records for the new domain to point to Google servers.

Google MX records:

ASPMX.L.GOOGLE.COM
ALT1.ASPMX.L.GOOGLE.COM
ALT2.ASPMX.L.GOOGLE.COM
ALT3.ASPMX.L.GOOGLE.COM
ALT4.ASPMX.L.GOOGLE.COM

How Domain Alias Works

After configuration:

• Every user automatically gets an alias email

• No need to create additional accounts

• Emails to alias domain arrive in the same inbox

Example:

john@company.com
john@company.in

Both emails reach the same Gmail mailbox.

Business Use Cases

Domain aliases are commonly used for:

• Companies owning multiple domains

• Brand protection

• Regional domains

• Email branding flexibility

Best Practices

When using domain aliases:

• Keep DNS records updated

• Configure SPF, DKIM, and DMARC for each domain

• Inform users about alias addresses

Conclusion

Domain aliases help organizations manage multiple domains efficiently without creating additional users. This feature simplifies email management and improves brand consistency across different domains.
