Email Header Analyzer
Check if an email is genuine. Paste headers or full source to spot spoofing and trace the relay chain. No data sent.
Privacy: All header analysis runs 100% in your browser — no header data is sent to any server. Optionally, clicking Run OSINT Analysis sends the originating IP and sender domain to the site's OSINT API for server-side enrichment; no email body or personal data is included.
How to get email headers or source
Paste the full email source or just the headers — the tool only needs the headers and will ignore the body automatically.
