About This Checker

What we check

We analyze your domain's email authentication: DMARC policy and alignment, SPF record and includes, and BIMI logo/CV when present.

Why it matters

Healthy authentication improves delivery and blocks spoofing. Major inbox providers increasingly require DMARC and robust SPF/DKIM practices for senders.

Included features

  • DMARC syntax, policy, and reporting validation
  • SPF record evaluation and include analysis
  • DKIM/SPF alignment interpretation
  • BIMI record and VMC detection
  • Clear setup and remediation guidance
