The EML, which is an acronym for E-mail, is the file extension of the Outlook Express Saved Mail Messages files. It belongs to the Microsoft's family of e-mail management programs and it is used for e-mails saving and forwarding purposes.

The header contains the e-mail addresses of the sender and the recipient, the subject, and the time and date of the message. The main message of the e-mail is in the body of the file. .EML can also contain hyperlinks and other attachments.
