EML is email in its most portable form. Based on the RFC 5322 standard, an EML file contains the complete email message — headers, body (plain text and HTML), embedded images, and attachments — in MIME format. Unlike MSG (Outlook-proprietary), EML is an open standard that virtually every email client understands.
The format is plain text at its core. You can open an EML file in any text editor and read the raw email headers and body content. The MIME structure separates the message into parts: text, HTML, attachments encoded in base64. Email clients parse this structure to render the formatted message.
Thunderbird, Apple Mail, Windows Mail, and most email clients open EML files with a double-click. Drag an EML file into Gmail's compose window to forward it. For bulk email archival, EML is the preferred format because it's standard, readable, and well-supported by archiving tools.
