These free email tools help with the parts of email that most apps hide. The Email signature generator builds a consistent signature you can paste into your mail client. The Email header analyzer reads raw headers to show the route a message took and its authentication results, which helps when you are checking a suspicious email or a delivery delay. The Eml viewer opens saved EML files, and Eml to PDF turns them into a document for records.
Choose by the file you have. If you have a saved message, open it in the Eml viewer first. If you only have the headers, paste them into the analyzer and compare the sender domain with the SPF, DKIM and DMARC results.

Common questions
Are my emails uploaded when I open an EML file?
No. The Eml viewer, Eml to PDF, Email header analyzer and Email signature generator run in your browser. The message is read on your device and is not sent to our server.
Can the header analyzer prove an email is genuine?
It reports what the headers say, including the hops a message passed through and the SPF, DKIM and DMARC results recorded by receiving servers. Headers can be forged before your provider receives them, so treat the analysis as evidence, not proof.
Where do I find the raw headers of an email?
Most mail apps offer an option such as Show original or View source in the message menu. Copy the full header block from there, including every Received line, and paste it into the Email header analyzer.
