eml.ninja
The email file editor that doesn't suck.
Open, edit, verify and export .eml files in the browser. Everything runs on the device, so nothing is uploaded and nothing is left behind.

The problem
Your files never leaveyour device.
Working on a raw email file usually means a desktop client that will not open it, or a web tool that wants the file uploaded first. Neither is acceptable when the file is evidence, a client record or an unreleased campaign. eml.ninja does the work in the browser tab and keeps the file on the machine it started on.

How it works
Three moves, start to finish.
Read it, then change it
Preview the HTML or flip to plain text, edit the body in place and correct headers inline. Attachments can be pulled out, added, removed or previewed without leaving the tab.
Prove it has not been touched
Ninja Verify checks DKIM, SPF and DMARC, scores the file out of 100 for tamper evidence and writes a forensic report. Preview how the message will land in Gmail, Outlook, Apple Mail, Yahoo or Thunderbird before it goes.
Get it back out in the right shape
Convert between EML and MSG in both directions, export to PDF, HTML or MBOX, and run more than fifty files through in one batch. A browser extension puts the same tools inside Gmail and Outlook Web.
