What is an EML File?
An EML file is an email message saved in the standard MIME RFC 822 format. EML files are used by various email clients including Microsoft Outlook, Thunderbird, Windows Mail, and Apple Mail to store individual email messages. These files contain the complete email structure including headers, body content, and attachments.
