Email Header Analyzer – Trace Email Origins & Auth Status
Email headers contain a wealth of metadata about a message’s origin, route, authentication, and spam filtering. This tool allows you to paste in raw email headers (from Gmail, Outlook, etc.) and automatically parses key elements like sender IP, mail server hops, SPF, DKIM, and DMARC results. It’s a vital resource for investigating phishing, spoofing, or delivery issues.
Security analysts, system administrators, and forensic investigators can use this tool to identify misconfigured mail servers, detect forged messages, and determine why a message landed in spam. It highlights authentication failures and routing anomalies — all done client-side to keep sensitive header data private.
