Please enter a domain name, URL, or email address.
This free online tool will search for the DMARC record and display it if it exists. Then, a series of diagnostic tests (DMARC-validations) will be performed on this record, and any errors that may affect email delivery will be shown.

- What is DMARC, and why is it important?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication system that helps protect domains from spoofing and phishing. It allows domain owners to define policies for handling unauthenticated email, which enhances the security of your email communications.
- How does the DMARC validator work?
The DMARC validator checks your domain’s DMARC settings by querying the DNS and analyzing the results. It provides information about the authentication status of your emails and helps identify potential configuration issues.
- What do I need to use the DMARC validator?
To use the validator, simply enter a domain name, an email address, or a URL into the designated input field on the page and click the “Check DMARC” button.
- How can I interpret the DMARC validation results?
The results of the validation will include information about your domain’s authentication status, DMARC settings, and any potential errors. If any issues are detected, you will receive recommendations on how to fix them.
- Can I use the validator for any domain?
Yes, you can use the DMARC validator to check the settings of any domain. This tool is helpful not only for your own domains but also for verifying domains from which you receive emails.
- What if my domain doesn’t have DMARC settings?
If your domain does not have DMARC settings, you should configure a DMARC policy. This involves adding the appropriate DNS record to your domain’s configuration. It is recommended to consult detailed DMARC setup documentation for further guidance.
- Why is DMARC so important for email security?
DMARC provides an extra layer of security by allowing organizations to monitor and report fraudulent acts involving their domains. It also helps email providers filter out spam and phishing emails, thereby increasing the trustworthiness of your sent messages.
- What other tools can help with managing email security?
In addition to DMARC, it is recommended to use SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to further protect your email communications and enhance authentication.
