How to add multiple domains to Google Workspace

Do you have multiple domains that you’d like to manage through the one Google Workspace installation? Find out how in this simple, easy-to-read article.

Do you have multiple domains that you’re managing? I’ve got quite a few myself and it was pretty exciting the day I realised I could add them all to Google Workspace – no more switching between accounts to answer emails or wondering why I couldn’t find a specific Google Doc (spoiler, it was in the ‘other’ account).

And today is hopefully your lucky day as well where I show you how to add a secondary domain or a user alias domain…

Hang on, secondary or user alias domains? What am I talking about?

Yeah I know, it’s confusing – sorry about that. Let’s back up a little bit and explain each of these in more detail.

Secondary domain = you pay for each user account that is added to that secondary domain, and they get a full, completely separate Google Workspace account. You’d use this if you were a large company with multiple brands, and different employees working for those multiple brands. Think Unilever – a company that covers multiple brands like Dove; Vaseline; and Sunsilk and whose employees are all working within those brands quite separately.

  • You can add upto 599 secondary domains to a single Google Workspace installation.

User alias domain = no extra cost per user; and users just get an email address at the other domain. You’d use this if it’s just you, or a couple of people, working for a couple of different brands. This would be the case for most solopreneurs who are perhaps managing a number of side hustles all by themselves.

  • You can add upto 20 user alias domains to a single Google Workspace installation.

Receive messages at your alias address

Messages sent to your alias address will automatically arrive in your inbox. To test, send a message from another account (not your Google Workspace account) to your new alias.

If you don’t receive the test message within 48-72 hours, contact your domain host. They can check whether your domain verification and MX records (for email) have been set up correctly.

Adding alias specific signatures

Once you’ve set up one or more email aliases, then you may want to also set up specific signatures for each address.

Removing a user alias domain

If you decide that you don’t want to have a particular domain associated with your Google Workspace, it is possible to delete it entirely.

Before you do this, if you are removing a secondary domain:

Regardless of whether you’re removing a secondary domain or a user alias domain, if you want to keep receiving email at these addresses you will need to ensure the MX records have been changed.

Once you’ve done that (if necessary) go to Manage domains. In Manage domains, scroll to the domain you’re removing, and click Remove / Remove domain alias.

Reusing your domain

Usually, you can reuse a domain’s name in your current Google Workspace account within 30 minutes of removing it. However, if the domain had a large number of users, you might need to wait up to 24 hours.

Note: To use the domain for a new Google Workspace account, you might need to wait up to 48 hours.
