Private by design
How this online EML viewer works
The selected EML file is read with the browser File API and parsed locally. Mailisk does not upload, store, or process the message on a backend service. If you refresh or close the page, the parsed result disappears.
HTML email content is sanitized and rendered in a sandboxed preview frame with remote network access blocked.
What you can inspect
- Subject, sender, recipients, reply-to, date, and message ID
- Full raw header list with folded values normalized for reading
- Plain text body plus sanitized HTML preview in a sandboxed frame
- Attachment names, content types, sizes, and local downloads
- MIME part structure for multipart and attachment debugging
