Firstly, you would need to verify your domains on Shopify. You can visit Shopify’s knowledge base to learn how to add a custom domain. After successfully adding and verifying your custom domain on Shopify, you will receive a confirmation message, after which you can process to set up your authentication protocols.
Note: If the domain is already added on Shopify, you will be able to spot a “Connected” status against it. In that case, you can directly move towards setting up DKIM.

Navigate to the Sender email page on the portal
On the page, click on Authenticate
This will redirect you to a new tab with instructions to publish 4 CNAME record in your domain’s DNS in order to enable DKIM for Shopify
Follow the instructions to visit your DNS provider’s management console and publish the records in the correct section

It will take your DNS 24-48 hours to process the changes, and you’re done!
Ensure that your DKIM record is syntactically correct. Finally, in order to start receiving reports on how your emails are performing, sign up for TDMARC today!
