Pass Your DMARC Checks
DMARC requires at least one authentication method (SPF or DKIM) to both pass and align with the Header From domain. Enter your domains on the left to verify if your email configuration achieves DMARC synergy.
DMARC Records Tools
Verify your DMARC alignment instantly. Compare your visible Header From domain against your hidden SPF Return-Path and DKIM signing domains to test strict and relaxed synergy across your email infrastructure.
DMARC requires at least one authentication method (SPF or DKIM) to both pass and align with the Header From domain. Enter your domains on the left to verify if your email configuration achieves DMARC synergy.
DMARC ties SPF and DKIM together. It verifies that the domain the user sees in their email client matches the domain that was actually authenticated behind the scenes.
From: address against the hidden Return-Path (or Envelope-From) address used for bounce processing. Often breaks when using third-party ESPs.From: address against the d= tag inside the cryptographic DKIM signature attached to the email headers.aspf=r or adkim=r), the domains just need to share the same Organizational (root) Domain. E.g., mail.example.com aligns with example.com.aspf=s or adkim=s), an exact string match is required. Subdomains are not permitted to align with root domains..co.uk or .com.au to ensure accurate relaxed checks.Your feedback has been submitted successfully.
