DMARC Checker

What Is DMARC?

DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. It’s an email authentication protocol that helps prevent attackers from spoofing your domain to send fraudulent emails.

When you set up a DMARC policy in your DNS records, it works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to:

• Verify the authenticity of your outgoing emails
• Tell receiving mail servers how to handle messages that fail authentication
• Generate reports so you can monitor email activity on your domain

What Is a DMARC Check?

A DMARC check is a diagnostic process that looks up and analyzes the DMARC record published in a domain’s DNS. This is also referred to as a DMARC record check or DMARC record lookup.

Using a DMARC check tool, you can:

• Verify if a domain has a DMARC record
• Check the syntax and structure of the record
• Understand the domain’s DMARC policy (none, quarantine, or reject)
• Confirm that reporting and enforcement are correctly set up

How to Check a DMARC Record

To check a DMARC record, all you need is the domain name. A DMARC record checker tool will perform a DNS query for the TXT record at:

CopyEdit

_dmarc.yourdomain.com

The result typically looks like this:

v=DMARC1; p=reject; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-failures@yourdomain.com; fo=1


This record means:

• DMARC version 1 is in use (v=DMARC1)
• Emails that fail DMARC checks should be rejected
• Aggregate reports are sent to the rua email
• Forensic failure reports are sent to the ruf email

DMARC Record Lookup Example

Let's say you run a DMARC record lookup for example.com and get this response:

v=DMARC1; p=quarantine; rua=mailto:reports@example.com; sp=none; fo=0


This means:

• The domain is using a quarantine policy (emails that fail DMARC checks may go to spam)
• Reports are being collected via reports@example.com
• Subdomains (sp) are not covered by the policy
• Forensic options (fo) are set to 0 (report only when both SPF and DKIM fail)

If the domain returns no DMARC record, that’s a red flag—email from that domain is not protected against spoofing.

Why Should You Use a DMARC Record Checker?

A DMARC record check is crucial for:

• Ensuring your domain is protected from spoofing
• Debugging email delivery issues due to incorrect policies
• Verifying your configuration after making updates
• Auditing third-party services that send email on your behalf

It’s also important if you’re an email marketer or business owner trying to improve inbox placement and build trust with recipients.
