Analyze Email Headers for Security & Authenticity
HeaderScope analyzes email headers to verify sender authenticity, detect spoofing attempts, and trace the email's journey through mail servers. Our tool checks SPF, DKIM, DMARC authentication, spam scoring, routing paths, and transport security - headers you paste are processed locally in your browser.
