DKIM is another important email authentication method apart from SPF that helps to ensure that the email sent from a domain is indeed by the authorised sender.
DKIM provides another way of associating a unique signature with each email sent.
How to setup DKIM records in Google Workspace:
If you are using Google Workspace, you can setup DKIM following the below steps:
Step 1: Navigate to the Admin Console
Login to the admin console by visiting admin.google.com and entering your admin credentials.
Step 3: Go to the "Apps" tab and select Google Workspace
In the Admin Console, click on the "Apps" tab and under that, select the “Google Workspace” option.
Step 4: Click on "Gmail"
Click on "Gmail" to access the Gmail settings in Google Workspace.
Step 5: Navigate to the "Authenticate email" section
Scroll down to the "Authenticate email" section and click on it. You will be able to find the configuration settings.
Step 6: Generate DKIM keys
In the DKIM configuration page, select the domain and click on "Generate new record." Google Workspace will generate specific DKIM keys for your domain.
Step 7: Add DKIM records to your DNS settings
Once you have created and copied the DKIM record, you need to add them to your DNS settings. Login to your domain registrar or hosting account and navigate to your DNS management section. You must add a new TXT record with the DKIM keys generated by Google Workspace.
Step 8: Start authentication and verify DKIM configuration
Once you have added the record to DNS, you can go back to the admin console and click on “Start authentication” in the same path to start DKIM validation.
You can verify your DKIM settings using the 3rd party tools as well. After adding a DKIM record, it is sent in every email and you can generally find it in the domain header.
Hope the guide helped you to set up DKIM records in Google Workspace.
