Is this a fake email?
Drop in the original email or paste its raw headers. Message Loupe checks 40+ sender, routing, authentication, and link signals, then gives you a plain-English verdict.
Caution: verify by phone
Sample result
The sender authentication passes, but the message asks for a wire transfer. Message Loupe will not call that safe just because the headers look clean.
Start with the original email
Regular forwarding strips out the evidence. Save the message itself, or use the raw-header view if downloading is not available.
Open the message menu, then choose Download message.
Use Save as, or copy the Internet headers from the message source.
Paste everything from Show original, View source, or View headers.
Scan the email
Your browser reads the file locally. We never receive the email, its headers, or the verdict.

Your email is not uploaded, logged, or analyzed by us. For some senders, your browser may ask public DNS for that domain's MX records or public RDAP for that domain's registration age.
Built for business email compromise checks
Message Loupe looks beyond links and attachments for text-only wire, invoice, payroll, and account-change requests.
A small team sends suspicious emails through one review path.
Gmail and Outlook prototypes are the next product surface.
Future team records keep verdict details, not message contents.
The parser and verdict logic run in JavaScript on your device. There is no upload step.
No cookies, tracking pixels, or third-party reputation calls touch your email data.
The methodology and code are public, so the privacy claim can be checked instead of trusted blindly.
