Email Header Analyzer & Phishing Checker

The Email Header Analyzer & Phishing Checker is a free, privacy-first cybersecurity utility created to uncover fraudulent, spoofed, or malicious emails. By analyzing the raw, cryptographic internet message headers hidden behind every email message, it verifies whether the sender is authentic or an impersonator.

Phishing, display-name spoofing, and Business Email Compromise (BEC) attacks frequently mimic recognizable brand logos, executive names, and financial institutions. However, scammers cannot forge cryptographic authentication signatures or legitimate email routing infrastructure. This tool inspects SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), DMARC (Domain-based Message Authentication, Reporting, and Conformance), sender alignment, server hops, and reply-to discrepancies.

100% Client-Side Privacy: Your sensitive email communications and security headers are processed entirely within your web browser using local JavaScript parsing. Nothing is ever uploaded to a remote server, tracked, or stored.

Every email carries hidden technical proof of where it really came from — even if the sender's name looks legitimate. This proof lives inside something called "email headers," which most people never see.

This tool reads that hidden proof and tells you, in plain language, whether the email actually came from who it claims to be from. We check three security systems that almost every legitimate company uses:

You don't need to understand any of the technical terms. We translate everything into a simple verdict — along with the specific reasons why.

Scammers are good at making fake emails look real. They can copy a bank's logo, font, and writing style perfectly. What they CANNOT fake is the technical trail left behind by real email servers — unless they've actually broken into the company's systems.

Looking at the sender's name or email address is not enough. A scammer can make an email LOOK like it's from "support@yourbank.com" — but the hidden technical proof will reveal it actually came from a completely different, unauthorized server.

This is exactly the kind of proof banks, email providers, and security teams use internally. We're just making it readable for everyone else.
