"No DMARC Record Found"

If you come across either of the following common prompts:

• No DMARC record 
• No DMARC record found 
• DMARC record is missing
• DMARC record not found 
• No DMARC record published 
• Unable to find DMARC record

This only implies that your domain is not configured with DMARC. Let’s take a look at what it is:

What is DMARC and why do you need email authentication for your domain?

In order to learn about how to fix the “No DMARC record found” issue, let’s learn what DMARC is all about. DMARC is the most widely used email authentication standard at the current time, which is designed to empower domain owners with the ability to specify to receiving servers how they should handle messages that fail authentication checks.

This in turn helps in protecting their domain from unauthorized access and email spoofing attacks. DMARC uses popular standard authentication protocols to validate inbound and outbound messages from your domain.

Protect Your Business from Impersonation Attacks and Spoofing with DMARC

Did you know that email is the easiest way cybercriminals can abuse your brand name?

By using your domain and impersonating your brand, hackers can send malicious phishing emails to your own employees and customers. Since SMTP is not retrofitted with secure protocols against fake “From” fields, an attacker can forge email headers to send fraudulent emails from your domain. Not only will this compromise security in your organization, but it will seriously harm your brand reputation.

Email spoofing can lead to BEC (Business Email Compromise),loss of valuable company information, unauthorized access to confidential data, financial loss and reflect poorly on your brand’s image. Even after implementing SPF and DKIM for your domain, you cannot prevent cybercriminals from impersonating your domain. 

This is why you need an email authentication protocol like DMARC, which authenticates emails using both the mentioned protocols and specifies to receiving servers of your clients, employees, and partners how to respond if an email is from an unauthorized source and fails authentication checks. This gives you maximum protection against exact-domain attacks and helps you be in complete control of your company’s domain.

Furthermore, with the help of an effective email authentication standard like DMARC, you can improve your email delivery rate, reach, and trust.

Adding The Missing DMARC Record to Your Domain

It can be annoying and confusing to come across prompts saying “Hostname returned a missing or invalid DMARC record” when checking for a domain’s DMARC record while using online tools.

For fixing the “No DMARC record found” issue for your domain all you need to do is add a DMARC record for your domain. Adding a DMARC record is essentially publishing a text (TXT) record in your domain’s DNS, in the _dmarc.example.com subdomain in compliance with DMARC specifications. A DMARC TXT Record in your DNS may look something like this:

v=DMARC1; p=none; rua=mailto:[email protected]

And Voila! You have successfully resolved the “No DMARC record found” prompt as your domain is now configured with DMARC authentication and contains a DMARC record.

But is this enough? The answer is no. Simply adding a DMARC TXT record to your DNS may resolve the missing DMARC prompt, but it is simply not enough to mitigate impersonation attacks and spoofing.

I’ve fixed the “No DMARC record found” error, what’s next?

Once you have a published DMARC record on your domain, it is important to make sure your published record is valid.

• Check your DMARC record with a DMARC record checker tool. It’s free!
• DMARC makes use of SPF and/or DKIM identifiers to verify the authority of sending domains. Make sure you have a valid and published SPF/DKIM record for your domain. 
• Monitor your domains and authentication results from time to time to track your email deliverability.
