What is a EML file?

An .EML file is a file format used to store a single email message, including file attachments. It typically contains the entire content of an email, including the message body, sender and recipient information, subject, attachments, and other metadata. EML files are plain text files and adhere to the MIME (Multipurpose Internet Mail Extensions) standard, making them compatible with various email clients and systems. This format allows for easy sharing and archiving of individual email messages, and it is commonly used for tasks such as email backups, migration, and legal documentation.
