EML vs MSG: Which Email Format Reigns Supreme?

The eternal debate between EML and MSG email formats has been a topic of interest for many users. As someone who has worked with email formats for years, I can attest that understanding the differences between these two formats is crucial for efficient email communication. In this article, we'll delve into the world of EML and MSG, exploring their history, technical specifications, and practical applications.

For those who may not be familiar, EML (Email Message Format) and MSG (Microsoft Outlook Email Format) are two popular email formats used to store and exchange email messages. While both formats serve the same purpose, they have distinct differences in terms of their structure, compatibility, and usage. As we navigate through this article, we'll examine the strengths and weaknesses of each format, helping you decide which one suits your needs.

Understanding EML and MSG Formats

EML is an industry-standard email format developed by Microsoft in the 1990s. It's based on the Internet Message Format (IMF) and is widely supported by most email clients, including Microsoft Outlook, Mozilla Thunderbird, and Apple Mail. EML files typically have a `.eml` extension and contain the email message, including the subject, body, and attachments.

On the other hand, MSG is a proprietary email format developed by Microsoft, primarily used by Microsoft Outlook. MSG files have a `.msg` extension and contain the email message, including the subject, body, attachments, and other metadata. While MSG is widely used in enterprise environments, its compatibility with other email clients is limited.

As shown in the table, EML is a text-based format that uses the Internet Message Format (IMF), making it easily readable and writable by most email clients. In contrast, MSG is a binary, proprietary format that's primarily used by Microsoft Outlook. This limited compatibility can make it challenging to exchange email messages between different email clients.

💡 As an expert in email formats, I can attest that EML's wide compatibility and text-based structure make it an ideal choice for email archiving and migration purposes.
