What is a .EML file?
EML is a single saved email message. Opened by Outlook, Thunderbird and Apple Mail.
- Did you know
- EML stores a single email in the layout defined for internet mail in 1982, and opens in Outlook, Thunderbird and Apple Mail.
- The .eml extension was introduced by Microsoft Outlook Express, and it has since become the near-universal single-message export.
- EML follows the MIME standard, which lets a single message carry attachments, rich content and non-ASCII text.
- What Analyser shows you
- Open email messages and mailboxes in the browser: single messages (EML, Apple Mail EMLX) and whole mailboxes (MBOX). Reads From/To/Subject/Date, counts the Received relay hops, surfaces SPF/DKIM/DMARC authentication results, lists attachments, and renders the message body (HTML sanitised with scripts and remote content removed, or plain text).
- Open a .EML file
- Drag a .EML file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
