What is an EML file?
An EML file is an email message saved by an email application, such as Microsoft Outlook or Apple Mail. It contains the content of the message, along with the subject, sender, recipient(s), and date of the message. EML files may also store one or more email attachments, which are files sent with the message.
Microsoft developed the Electronic Mail (EML) format to comply with the industry-standard RFC 5322 for transferring messages between email clients. EML utilizes the Internet Message Format (IMF) syntax for text stored in the messages.
NOTE: You can create an EML file with Apple Mail by selecting an email message, then clicking File → Save As... and choosing "Raw Message Source" in the "Format" dropdown menu.
How do I open an EML file?
You can also open EML files with various web browsers, including Google Chrome (multiplatform), Microsoft Edge, and Internet Explorer since they are formatted similar to .MHT files. You can change the .eml file extension to .mht and open it directly with the web browser.
Since EML files are partially saved in plain text format you can open them with a plain text editor, such as Microsoft Notepad and Apple TextEdit. However, you may need to change the .eml file extension to .txt.
