Email Header Analyzer
Run the test
Paste raw email headers and inspect delivery hops, authentication results, timestamps, and addresses locally in your browser.
Start the test to generate current evidence. Nothing is pre-scored.
A result describes what this browser and this request exposed at the time of testing. It is not a certification of security or anonymity.
How to interpret it
These answers describe the tests boundaries before you rely on a result.
Are pasted headers uploaded?
No. The parser runs in the current page in Release A.
Can headers prove who wrote a message?
They can support delivery and authentication analysis, but forwarded mail, relays, compromised accounts, and forged fields limit certainty.
Can this tool prove I am completely private?
No. It reports evidence visible to this browser and request. It does not certify anonymity, device security, identity, or every application route.
