Email Header Analyzer is a free online tool that helps you trace the origin of an email by decoding its raw header. Instantly identify the sender's IP address, mail server hops, SPF/DKIM/DMARC authentication results, and relay delays. This tool detects spoofing attempts and provides a clear Pass/Warning/Fail score for email trust.
