To configure your domain's email with Google Workspace (formerly Google Apps), you need to update the DNS records, specifically the MX records, so that email is routed to Google's servers.

1. Access cPanel

• Log in to your cPanel account.
• Find the Domains section and click on Zone Editor.

2. Edit the DNS records

• On the Zone Editor screen, find the domain you want to configure for Google Workspace.
• Click Manage next to the domain to access the DNS record editor.
• In the filter, select "MX" and you will see something similar to the following: 
  

3. Delete the existing MX records

Before adding Google's MX records, delete any existing MX records. This is done by clicking the red "Delete" button.

4. Add Google's MX records

The MX records required to route the email service to Workspace are the same for all domains; therefore, you must use the following:

Now that you have the MX record information you need to add, follow these steps for each record you are going to create.

1. Click Add Record.
2. In the record type field, select MX.
3. Name, enter:  yourdomain.com
4. TTL, enter: 120
5. Type, enter: MX
6. Priority, assign the corresponding priority (for example, 1 for ASPMX.L.GOOGLE.COM.).
7. Destination, enter the MX server (for example, ASPMX.L.GOOGLE.COM.).
8. Save the changes.
   

This is how your DNS table should look once you have finished creating all the records.

After adding the records, DNS propagation can take up to 48 hours, but it usually completes within a few minutes.

Once this is done, all email for your domain will be routed to Google Workspace servers.
