Paste a message’s raw headers to see the routing path and the authentication results it carries. Analysis happens only in this browser. Emberix does not upload, store, or receive what you paste.
How to read the result
- Authentication results show what a receiving mail system recorded for SPF, DKIM, DMARC, or ARC. They are useful evidence, but only the recipient’s trusted mail system can make them authoritative.
- Routing hops are shown oldest first. Received fields can be added or forged before a message reaches a trusted provider, so use them as clues rather than conclusive proof.
- Transport evidence means a hop mentions TLS or an encrypted SMTP protocol. It does not prove every hop used encryption or that the message was encrypted end to end.
Privacy and handling
The analyzer is client-side JavaScript. It makes no network request and does not write your headers to browser storage. If you save or share a result, use a redacted copy and review it first, because header fields can contain email addresses, IP addresses, hostnames, message IDs, and internal routing detail.
