Sendmarc’s record checker is an online diagnostic tool that helps identify, validate, and troubleshoot the record published in a domain’s DNS.
The DMARC lookup tool analyzes the domain’s record for:
Additionally, please check your organization’s domain score to manage its domain to the highest DMARC levels.
DMARC is an email authentication protocol that protects a domain from unauthorized use, such as phishing, spoofing, and other email-based attacks, by verifying that emails sent from the domain are legitimate.
Without a valid record, a domain is vulnerable to email-based threats. Regular checks help ensure that the domain’s DMARC policy is correctly configured and compliant with industry standards.
A DMARC checker is essential for any business concerned with email security and deliverability.
Check if DMARC is enabled to identify and correct syntax or policy mistakes that could expose the domain to cyberthreats.
A properly configured record improves email deliverability and reduces the likelihood of legitimate messages being marked as Spam.
Stay aligned with evolving DMARC requirements from major email providers, such as Google, Yahoo, and Microsoft.

Performing a DMARC record check is straightforward.
Input the domain name into the required field.
The tool fetches the DMARC TXT record from the DNS and displays it in an easy-to-read format.
RUA and RUF)Tip: Regularly perform a DMARC test on your company’s record, especially after making changes to DNS settings or if email deliverability issues are seen.
If errors or misconfigurations are found, the checker recommends taking action.
| Host | Type | Value |
|---|---|---|
| _dmarc.yourdomain.com | TXT | v=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected]; |
This example sets the policy to quarantine and specifies where to send aggregate and forensic reports.
If a record is missing or incorrectly configured, the domain is at risk. DMARC verification helps detect common issues, such as:

A DMARC record is a DNS TXT record that defines a domain’s DMARC policy. This policy tells receiving email servers how to handle unauthenticated emails. A record includes information such as the policy setting (none, quarantine, or reject), the percentage of emails the policy applies to, and the reporting addresses for aggregate and forensic reports.
A valid DMARC DNS record includes required tags and correct syntax. An example of a valid record is:
| Host | Type | Value |
|---|---|---|
| _dmarc.yourdomain.com | TXT | v=DMARC1; p=quarantine; rua=mailto:[email protected]; |
If a DMARC DNS record is misconfigured, email servers might ignore it, leaving the domain vulnerable to phishing and spoofing attacks. Also, incorrect DMARC records can cause legitimate emails to be delivered to Spam folders or rejected.
To fix a DMARC misconfiguration, use a checker tool to identify syntax or policy errors. Then, update the DNS with a corrected record. After making changes, run the checker again to verify the fix.
DMARC affects email deliverability by improving inbox placement and reducing the likelihood of emails being marked as Spam or rejected by receiving servers.
No, a domain should have only one DMARC record. Having multiple DMARC records causes processing errors and might result in the DMARC policy being ignored.
Yes, DMARC is still necessary even if Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) are in place. DMARC builds on SPF and DKIM by adding policy enforcement and reporting features, offering more complete protection against email impersonation.
Sendmarc’s DMARC record checker is a free, fast, and accurate tool created to help organizations validate their DMARC records with ease. It offers a beginner-friendly interface with clear explanations, making it accessible to users with varying levels of technical expertise.
