Email Header Analyser

Paste the raw headers from an email to see where it really came from, whether it passed SPF/DKIM/DMARC, its delivery path, and any signs of spoofing or phishing.

🔒 Everything is parsed in your browser. Headers can contain sensitive information — nothing is uploaded or stored.
