Introduction
Email authentication is crucial for ensuring that your messages reach recipients' inboxes without being flagged as spam. Among the essential authentication protocols, DKIM (DomainKeys Identified Mail) plays a significant role in verifying the authenticity of your emails. However, there are instances where DKIM validation may fail, leading to potential issues with email delivery and credibility.
In this article, we explore the common reasons why DKIM validation might not work as expected. From configuration errors to DNS propagation delays, understanding these factors can help you troubleshoot and resolve the issue effectively. Let’s dive into the key challenges behind DKIM validation failures and how to address them for seamless email authentication.

Here are the reasons why DKIM is not getting validated -:
1.) You Have Not Added CNAME to Your Domain Provider: For DKIM validation to work, a CNAME record containing the DKIM key must be added to your domain's DNS settings. This record allows email recipients to verify that the emails are authorized by your domain. If this step is skipped or the record is not correctly configured, DKIM validation will fail, as the necessary information cannot be accessed by the recipient's mail server.
Note: Follow the below step to check if the CNAME has been added or not -:
1.) https://www.whatsmydns.net/ -- Go to - https://www.whatsmydns.net/, search the host & CNAME with the store URL. (Example: my Host is ai and my URL is aitrillion.com so you need to add ai.aitrillion.com.) Select the CNAME >> and click on Search.
(Similarly, you need to add all the host -- s1._domainkey and
s2._domainkey with values)
You will get a tick mark if it has been added or a cross mark if it has not been added
Note📝: You need to add all the three entries. If not done it will show as cross mark.
Note📝: If the CNAME details for DKIM are not available on either website, you need to add the CNAME to your domain provider, such as GoDaddy, Namecheap, or Hostinger.
2.) Incorrect DKIM Key Configuration: The DKIM key provided by AiTrillion may not be correctly added to your domain's DNS settings. Ensure that the selector and the key are entered precisely as provided.
Note📝: You just need to copy the host without the domain (As shown in the below screenshot)
