Email (.eml) analyzer.
Drop in an .eml file and see its SPF, DKIM, DMARC and alignment. Runs entirely in your browser; nothing is uploaded.
This runs entirely in your browser.
Your message is read and parsed on your own device. Nothing is uploaded, so even a malicious file never touches our systems. Want to be sure? Open your browser's DevTools → Network tab and drop a file: you'll see zero requests. Or turn off Wi-Fi, it still works.

Links & addresses in the body
Shown as plain text and deliberately not clickable, so a hostile link can't be followed by accident. Any flags are structural hints read from the URL itself, not a reputation check; we never look anything up.
This check is a snapshot. dmarcula watches your domain around the clock, reads the DMARC reports for you, and emails you when something changes. Free, no credit card.
