Convert email archives to structured Markdown

Email exports are awkward to search, archive, or feed to an LLM. Scan Hero converts .eml, .msg, .mbox archives, and full .pst mailboxes into structured Markdown — YAML front-matter for from/to/subject/date, clean body text, and an attachment inventory per message.

PST files can contain thousands of emails, so set a limit when you need one. Email files are auto-deleted from storage within one hour for compliance.

Input: .eml, .msg (Outlook), .mbox, .pst (Outlook archive)Output: Markdown (.md) with YAML front-matter

Example: Corporate emails → structured Markdown

Convert .eml, .msg, .mbox archives, or full .pst files into structured Markdown with YAML front-matter headers, clean body text, and attachment inventory.
