Email with Attachment (EML)
A multipart/mixed email with a base64-encoded CSV file attachment — for testing attachment detection, decoding, and extraction from an EML message.
The email category gives message parsers, importers, and forensic tools real, documented fixtures. The EML set is standards-compliant RFC 822/MIME: a plain-text message, a multipart/alternative message carrying both a text and an HTML body, and a multipart/mixed message with a base64-encoded file attachment — each with full headers (From, To, Subject, Date, Message-ID, MIME boundaries). An MBOX mailbox concatenates a short three-message thread with the classic 'From ' separator lines, so you can test mailbox splitting and thread reconstruction. Every message uses fixed dates, message IDs, and boundaries for reproducibility, and every address and name is fictional. Use them to test header parsing, MIME decoding, attachment extraction, HTML-part sanitising, and EML-to-other-format conversion.

MBOX Mailbox (three-message thread)
An mbox mailbox concatenating a short three-message email thread with the classic 'From ' separator lines and >From body escaping — for testing mailbox splitting and thread reconstruction.
Multipart Email — Text + HTML (EML)
A multipart/alternative email carrying both a plain-text and an HTML body — for testing MIME part selection, HTML-part handling and sanitising, and multipart parsing.
Plain-Text Email (EML)
A standards-compliant plain-text email message (.eml) with full headers — the simplest valid RFC 822 message for testing email header parsing and EML import.
