RESEARCH DOSSIER / 2026
Across 999 of 1,000 observed Tranco-ranked domains, 71.9% published valid DMARC and 83.1% of those publishers enforced quarantine or rejection. This is direct public-DNS measurement of ranked domains—not a brand-value, deliverability or incident score.
WHY THIS MATTERSThis DNS benchmark measures a domain owner’s published direction for failing mail—not inbox placement or fraud—but an enforcing policy gives participating receivers more instruction when a forged exact-domain message fails aligned authentication.

NAMED-ROW DATA
Each row is the exact Tranco-ranked hostname scanned in the recorded window. Tranco rank is a web-domain popularity signal, not a corporate revenue or brand-value score. The CSV and JSON contain the full published field set, including MX answers and aggregate-report destination domains without mailbox local parts.

“No valid DMARC” and “no SPF” describe records observed at the named DNS location during this scan. They do not establish missing mail authentication on every sending subdomain, a delivery outcome, compromise or an incident.
WHY THIS MATTERS
High-visibility web domains are familiar to customers, staff and partners. A missing or monitoring-only DMARC policy leaves less protection at participating receivers when a forged message using the exact visible From domain fails aligned authentication.
Learn how DMARC evaluates a message →01 / DOMAIN IDENTITY
An attacker can send a message that displays the organization's exact domain in the From line. Without a valid DMARC record, participating receivers have no DMARC handling request from that domain owner when aligned SPF and DKIM fail.
02 / PRACTICAL HARM
A forged message can imitate a widely recognized domain in an account, billing, support or delivery workflow. That can make a malicious link or payment request more convincing. A public DNS observation does not show that any such message was sent, delivered or acted on.
THREE DIFFERENT DNS STATES
Risk, not incident evidence: this DNS state does not prove spoofing, fraud, compromise or weak internal controls. DMARC also does not stop lookalike domains, abuse of a compromised legitimate account or every phishing technique.
