Files are parsed in this browser tab. Remote email content is blocked in previews.01 / WORKFLOW
From mailbox export to readable evidence.
MailFrame decodes RFC 5322 headers and MIME bodies locally, while keeping remote trackers and active email content out of the preview.
Search and inspect
Filter by subject, sender, recipient, or body. Preview sanitized content before selecting messages.
Save what matters
Export text, standalone HTML, print-ready PDF, and attachments in a separate reviewed ZIP.
02 / SAFETY MODEL
Email should not phone home when you open it.
LOCAL / 01
No mail upload
Parsing and conversion happen in browser memory. Mail content is not sent to MYMONDAY.AI.
BLOCKED / 02
No remote images
Scripts, forms, links, inline styles, and remote resource attributes are removed before HTML preview.
HONEST / 03
Attachments stay untrusted
Extracted attachments are never executed by MailFrame. Review them with appropriate security software before opening.
03 / QUESTIONS
Before you open old mail.
Does MailFrame upload my messages?
No. EML and MBOX files are parsed locally in the browser. The service has no mail upload or conversion endpoint.
Can an email tracking pixel load in preview?
MailFrame removes remote URL attributes and displays HTML inside a sandboxed iframe with a restrictive content security policy.
Which MBOX variants are supported?
MailFrame recognizes conventional “From ” separator lines described by the application/mbox format. Site-specific variants or damaged archives may not split correctly.
Does PDF preserve the original layout exactly?
No. PDF uses a clean print representation designed for reading and archiving, not forensic byte-for-byte reproduction. Keep the original EML or MBOX.
Are extracted attachments safe?
Not necessarily. MailFrame only copies attachment bytes into a ZIP. Scan and review files before opening them.
