What are EML files & how to access them?
EML files are individual email message files that contain the full content and structure of an email. They store the email message, including the mail headers, body text, and attachments. EML files are compatible with a large number of email clients.
As the EML files are compatible with many mail applications, when an email is sent or received by an email client program like Outlook or Thunderbird, the message can be saved on your computer as an EML file. This allows the single email to be stored for later use independent of the email server or client it originally came from. Given an email file in EML or MSG format, you can open the EML file with this tool.
How to open EML files?
To open an EML file, you can use an email client like Outlook, Thunderbird, or Apple Mail. These email clients can open EML files directly, allowing you to view the email message, attachments, and other details. Alternatively, you can use this free EML viewer tool for the same purpose.

What is the difference between EML and MSG files?
EML is a universal, text-based email standard (RFC 5322) that works with any email client. MSG is Microsoft Outlook's proprietary binary format. Both store the same email content; EML is more portable while MSG is optimised for Outlook.
Are EML files safe to open?
EML files are plain text and do not execute code on their own. The risk comes from clicking links or opening attachments inside them. Using a browser-based EML viewer means the email is displayed but never executed.
