What Is a EML File?
EML is the standard file format for individual email messages, used by Microsoft Outlook, Mozilla Thunderbird, Apple Mail, and most email clients to export saved messages. An EML file is a plain text file that follows the RFC 5322 Internet Message Format — it stores the full message headers (From, To, CC, Date, Subject), the message body in plain text and HTML, and any attachments encoded as MIME parts. EML files are commonly created when exporting, archiving, or migrating emails between systems, and are often the deliverable in legal e-discovery and compliance processes.
