It is very easy to verify your domain. All you have to do is log in to your domain registrar dashboard and add some DNS records. DNS records are settings maintained by your domain name registrar to direct internet traffic to your domain name.
Google gives you a TXT verification record to add to your domain's DNS records. When Google sees that the record exists, your domain ownership is confirmed. This protects your domain by ensuring that only you can use it. This won't affect your website, mail flow, or other services.
Step 1: Get your unique TXT verification record
Just so you know, you may also access G Suite Admin Console and your G Suite Webmail from inside your Rocket Domains MissionControl Dashboard which also allows you to upgrade your G Suite Basic to G Suite Business and order more mailboxes/seats/licenses in a few clicks.
Click on the option which says "Set up Admin Console" or "Admin Console Set up".
Click Verify Domain Ownership and hit Next.
Click Begin Verification
You can also click Switch verification method if you need to use another method
Step 2: Log in to your Domain DNS Records
If your domain is hosted by Rocket Domains, go into your domain's settings, click on Web Apps, and select G Suite.
All you need to do then is enter Google's verification code, hit Connect, and Wallah you're all set!
With Rocket Domains, it is as simple as that.
If, however, your domain is not hosted by Rocket Domains, please follow the steps below:
For the record type, select TXT.
In the Name/Host/Alias field, enter @ or leave it blank.
Your host might require you to enter your domain, which looks like yourdomain.com, into this field. Your other DNS records might indicate what you should enter.
In the Time to Live (TTL) field, enter 86400 or leave the default.
In the Value/Answer/Destination field, paste the verification record you copied in step 1
Save the record.
Note: If you see a warning about changing your DNS settings, you can disregard it. Adding the TXT record won’t damage your website or DNS settings.
Step 4: Tell Google that Verification Record Has Been Added
Return to the Admin console. If necessary, click the link at the top of the page to continue setting up the Admin console.
If you can't find that link, look for the same "Admin Console Setup" option.
Navigate to Verify your domain page.
Scroll to the bottom of the page and click Verify my domain.
After completing domain ownership verification, you can proceed to setting up Gmail with G Suite. Keep the Admin Console and your domain host site open in your browser. In a new tab or window, open detailed instructions for setting up Gmail with your host.
If you need help with the verification you can contact your Google Workspace Support at Rocket Domains Ground Control.
