The Simple Guide To Fix “no DMARC record found” Errors

Let’s cut to the chase: Your emails are at risk. Every message sent without a DMARC record is like sending your brand’s reputation into the wild, unprotected. “No DMARC record found” isn’t just an error message; it’s a red flag that your emails could be one phishing attack away from a trust crisis with your clients. Here, we’re diving deep into DMARC, stripping away the jargon, and giving you straightforward how-tos on safeguarding your emails from deceptive attacks.

Why You Need DMARC

DMARC (Domain-based Message Authentication, Reporting & Conformance) stands out as an essential shield, safeguarding your domain from the pervasive threats of email spoofing, spam and phishing attacks. Imagine a scenario where cybercriminals exploit your domain, sending malicious emails that appear genuine to your clients and partners. Not only does this tarnish your brand’s reputation, but it also erodes the hard-earned trust among your stakeholders. DMARC steps in here, meticulously authenticating your emails and specifying policies to manage those that fail the email authentication, ensuring that your communications remain secure and are delivered accurately to the recipient’s inbox.

DMARC transcends being a mere protective tool by offering insightful reports about your email ecosystem, illuminating the path for you to enhance your email security further. It provides a comprehensive view of your email channels. This allows you to discern between legitimate and fraudulent activities, thereby allowing you to make informed decisions to boost your email security.

Why Your DMARC Records Were Not Found

Two distinct approaches address the “No DMARC record found” issue. Situation 1 focuses on swiftly eliminating the error message by adding a basic DMARC TXT DNS record to the subdomain, using a simple record like v=DMARC1; p=none; rua=mailto:[email protected]. While this method eradicates the error message, it doesn’t significantly protect against email spoofing or impersonation attacks since the policy is set to “none”.

Method 2, conversely, aims for comprehensive protection against email impersonation and spoofing, necessitating a thorough understanding of DMARC mechanics and a meticulous, potentially lengthy implementation process. Achieving 100% protection is complex and risky, as incorrect configurations can result in legitimate emails being rejected.

How ToFix “No DMARC Record Found” Issue & Add Your Missing DMARC Record

Addressing the “No DMARC Record Found” or invalid DMARC record is pivotal in fortifying your domain against email spoofing and phishing attacks, thereby safeguarding your brand’s reputation and enhancing email deliverability. The resolution involves a three-step approach: generating a DMARC record, publishing it to your domain’s DNS, and verifying its implementation.

Utilize online DMARC record generators to create a record, ensuring to specify an appropriate policy and report email address. Subsequently, publish the record to your DNS by adding a TXT record to the subdomain. Finally, employ DMARC record checkers to validate the implementation, ensuring that your domain is protected and that you begin receiving insightful DMARC reports, thereby establishing a secure, authenticated email communication channel for your domain.

Step 1: Generate DMARC Record

Begin by generating a DMARC record, a text (TXT) record that will be added to your domain’s DNS. The record typically includes the DMARC version, policy, and email address for aggregate reports. Utilize online DMARC record generators to create a record suitable for your domain, ensuring to set an appropriate policy (e.g., ‘none’ for monitoring, ‘quarantine’ to hold suspicious emails, or ‘reject’ to decline them) and specify an email address to receive reports.

Step 2: Publish the DMARC Record to Your DNS

Once the DMARC record is generated, it must be published to your domain’s DNS. This involves adding a TXT record to your DNS settings. The record should be added to a subdomain labeled dmarc, followed by your domain name (e.g., Ensure that the value of the TXT record is the DMARC record generated in Step 1. Different DNS providers might have varied interfaces, but the process generally involves navigating to your DNS management page, adding a new TXT record, and inputting the DMARC details.

Step 3: Verify the DMARC Record

After publishing, verifying the DMARC record published correctly is imperative. Ensure it’s implemented correctly and is detectable by email servers. Utilize online DMARC record checkers to validate the record by inputting your domain and ensuring the published DMARC record is found and configured correctly. This step ensures that your DMARC policy is active, and you will receive DMARC aggregate reports to the specified email address, providing insights into your email domain’s activities.


Publishing an SPF (Sender Policy Framework) record and setting up DKIM (DomainKeys Identified Mail) email authentication are integral steps that relate to DMARC, especially when addressing a DMARC authentication issue. Here’s how they interconnect:

1. Publish SPF Record

SPF allows email senders to define which IP addresses are authorized to send emails on behalf of a domain. When an SPF record is published in the domain’s DNS, receiving email servers can check the SPF record to verify that incoming emails from the domain are being sent from an allowed IP address. The email can be marked as spam or rejected if the check fails. In the context of DMARC, SPF is one of the two email authentication mechanisms (alongside DKIM) that DMARC uses to verify an email message’s authenticity.

2. Setup DKIM Authentication

DKIM involves adding a digital signature to the headers of an email message. This signature can be verified by receiving email servers using the DKIM record published in the sender’s DNS. Check DKIM records and if the verification succeeds, it confirms that the email was not altered in transit, ensuring the integrity of the message. DMARC relies on DKIM as the second email authentication mechanism, alongside SPF, to validate the authenticity of email messages.
