After verifying your domain ownership for your secondary domain or domain alias, changing your MX records to Google Workspace is usually the next step. However, some Google Workspace customers won’t need to change their MX records -- for example, if they set up their domains using an inbound mail gateway.
If you don’t need to change your MX records for your secondary domain or domain alias, click Skip Google MX setup on the Domain settings page to activate Gmail for this domain. This setting enables you to activate the domain even if you are routing its email through a mail server that's not hosted by Google. This might be your own on-premise server, or a third-party service that provides email archiving or spam protection.
To activate your secondary domain or domain alias without changing the domain’s MX records to Google Workspace:
- Add your domain to the Domain settings page, and verify your domain ownership.
- Click Skip Google MX setup for your secondary domain or domain alias (listed on the Domain settings page).
- To verify that you are routing your mail to another server, click I use another mail server.
The status for your domain will then change to Active.
