File extension eml is used for e-mail messages. EML, an acronym for E-mail, is the file extension of the Outlook Express Saved Mail Messages files. It belongs to Microsoft's family of e-mail clients and is used for e-mail saving and forwarding. The successor of Outlook Express is free Windows Live Mail.

Since the purpose of an EML file is to store e-mail messages, it is a plain text file and, as a result, has a standard file structure. It usually consists of a short header and the main body. 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 files can also contain hyperlinks and other attachments.

EML files are created to comply with the industry RFC 822 standard, they can be used with most e-mail clients, servers, and applications. EML files can be opened using most e-mail clients, such as Microsoft Outlook, Mozilla Thunderbird, Apple Mail, and others.
