Email Header Analyser
Paste the headers from a suspicious email to see who really sent it, whether it passed SPF, DKIM and DMARC, and the path it took to reach you.
How to find the headers
Outlook (new Outlook and Outlook on the web): open the email, select the three dots (More actions), then View, then View message source or View message details.
Outlook classic for Windows: open the email in its own window, then File, Properties, and copy everything in the Internet headers box.
Gmail: open the email, select the three dots, then Show original, and copy the text.
Apple Mail: open the email, then View, Message, All Headers.
The analysis runs entirely in your browser. The headers you paste are never sent to Netoja or anyone else. Results are based on what the receiving mail server recorded and are guidance only; if an email asks for money, passwords or bank changes, verify it by phone using a number you already have.
