Troubleshooting Sender Email Authentication Issues on Shopify: A Comprehensive Guide


As an eCommerce entrepreneur using Shopify for your online store, you may encounter challenges when trying to authenticate your Sender Email address for notifications. This problem can be frustrating, especially when you've followed all instructions provided by Shopify and your domain provider.

Reasons and Causes of Authentication Issues

There are several reasons why Shopify may fail to authenticate your Sender Email address despite your efforts:

  1. Incorrect C-NAME Records: One of the most common causes of authentication issues is incorrect C-NAME records. Even if your domain provider, in this case, 123Reg, claims to have added the records correctly, a small mistake can lead to authentication failure.

  2. Propagation Delay: Sometimes, changes to DNS settings, such as adding C-NAME records, can take time to propagate across the internet. This delay in propagation can cause authentication failures even after the records have been added correctly.

  3. SPF and DKIM Setup: Shopify requires proper SPF and DKIM setup for email authentication. If these settings are not configured correctly in your domain settings, Shopify may fail to authenticate your Sender Email address.

Guide to Solving Authentication Problems

To fully solve the problem of Shopify not authenticating your Sender Email address, follow these steps:

  1. Verify C-NAME Records: Double-check the C-NAME records added to your domain settings. Ensure that there are no typos or errors in the records. You may need to delete and re-add the records to rule out any issues.

  2. Wait for Propagation: If you've recently updated your DNS settings, wait for at least 24-48 hours for the changes to propagate. Sometimes, patience is key when it comes to DNS changes taking effect.

  3. Check SPF and DKIM: Verify that your domain has the correct SPF and DKIM records set up. These settings play a crucial role in email authentication and can impact Shopify's ability to authenticate your Sender Email address.

  4. Reach out to Support: If you've tried all troubleshooting steps and still can't authenticate your Sender Email address, reach out to Shopify support for further assistance. They may be able to provide specific guidance or escalate the issue if needed.
