What is EML file?

Files with the .EML extension contain a single email stored in a single file comprised of the header of the message and its body, and possibly some attachments. This extension is used by many various email managing programs. The format was standardised in the RFC 2833 document.

A header of a message includes:

  • Email addresses of sender and receiver,
  • Subject of the message,
  • Date, time and place of origin – servers mediating reception of the message,
  • Additional information about the content, links and attachments.

The EML message files can be sent as attachments to other email messages. They can be opened in most email client programs. Such programs usually also enable storing messages in EML format on disc, for instance, for purpose of archiving.
