Paste raw email headers to summarize SPF, DKIM, DMARC, Received hops, delays and key message fields.
This analyzer is for support, deliverability and security triage when someone forwards raw email headers. Paste the headers and review authentication results plus the Received chain.
What it reports
The output summarizes SPF, DKIM and DMARC results from Authentication-Results, common message headers, Received hops and large timestamp gaps between hops.
Privacy
Email headers may contain private addresses, IPs and internal hostnames. The analyzer runs locally in the browser and does not send pasted text to a server.
