EML (Email) is a file format used by email clients to store email messages. An EML file contains the email headers, body text, HTML content, and any attachments encoded in MIME format. The format follows the RFC 822 and RFC 2822 standards for internet message format. EML files store the complete email message including From, To, Subject, Date, and other metadata fields, along with the message body and optionally multipart MIME sections for attachments and alternative content types. EML files are supported by Microsoft Outlook, Mozilla Thunderbird, Apple Mail, Windows Mail, and most other email clients. They are commonly used for email archiving, backup, and forensic analysis.
