Email headers contain metadata about the path an email took from sender to recipient. To access them in Gmail, open the email → three-dot menu → "Show original". In Outlook, open the email → File → Properties.
Our tool parses the raw headers to show you the full delivery chain, detect IP spoofing, and verify SPF, DKIM, and DMARC authentication results, the three main anti-phishing standards.
