Email Security Ratings
Our email validation CSV free tool includes comprehensive DNS security checks
Fully Secured & Enforced
Highly Deliverable & Secure. Has SPF and DMARC with p=reject policy. This indicates a legitimate domain that actively sends emails and takes security seriously.
Authenticated with Quarantine
Deliverable but May Go to Spam. Has SPF and DMARC with p=quarantine policy. Offers good protection but may quarantine suspicious emails.
Authenticated but Unprotected
Likely Deliverable. Has SPF and DMARC with p=none policy. The domain sends emails but only monitors authentication failures.
SPF Only, No DMARC Protection
Likely Deliverable. Has SPF but is missing DMARC records. Basic sender authentication without failure handling instructions.
DMARC Without SPF, Strict Rejection
Likely Rejected. Missing SPF but has DMARC with p=reject policy. This unusual configuration may lead to email delivery problems.
DMARC Without SPF, Possible Spam
May Go to Spam. Missing SPF but has DMARC with p=quarantine policy. Unusual configuration that may impact deliverability.
DMARC Set, No Authentication
Highly Spoofable. Missing SPF but has DMARC with p=none policy. Provides minimal protection against email spoofing.
