DMARC Lookup Tool

Check your domain's DMARC records to verify email authentication and prevent spoofing.

What is a DMARC Lookup Tool?

A DMARC (Domain-based Message Authentication, Reporting, and Conformance) lookup tool retrieves the DMARC record of a domain. DMARC records define how email servers should handle unauthenticated messages, helping to prevent email spoofing and phishing.

How to Use the DMARC Lookup Tool

  • Enter the Domain: Input the domain name you want to check (e.g., example.com).
  • Click 'Check DMARC Record': The tool will query the DNS and fetch the DMARC record for the domain.
  • Review the Result:
    • Policy: Specifies how the domain handles unauthenticated emails (e.g., none, quarantine, reject).
    • Reporting: Indicates the email address where DMARC reports are sent.
    • TTL (Time To Live): The time the record is cached before refreshing.

2. Why is DMARC important?

DMARC protects your domain from spoofing and phishing by enforcing authentication policies. It also provides reports to help you monitor and improve your email security.
