What is EMAIL File Format
An email file has a specific format that is recognized by email programs. The format includes a header and a body, which are separated by a blank line. The header contains the senders email address, the recipients email address, the subject of the email, and the date and time the email was sent. The body of the email contains the actual message. Email files can be in either plain text or HTML format. HTML emails are more common these days, as they can include images and other formatting.

Introduced and documented by Microsoft, the Rich Text Format (RTF) represents a method of encoding formatted text and graphics for use within applications. The format facilitates cross-platform document exchange with other Microsoft Products, thus serving the purpose of interoperability. This capability makes it a standard of data transfer between word processing software and, hence, contents can be transferred from one operating system to another without losing document formatting. The file format specifications are available by Microsoft for public download and can be referred to from developer's perspective. One of the key advantages of RTF is its ability to preserve formatting across different word processors and text editors. This means that you can create an RTF document in one application and be confident that it will look the same when opened in another application, even if the two applications use different default fonts, font sizes, and other formatting options.
