Standard RFC 1896

Enriched text is a formatted text format for e-mail, defined by the IETF in RFC 1896 and associated with the text/enriched MIME type. It is "intended to facilitate the wider interoperation of simple enriched text across a wide variety of hardware and software platforms". As of 2012, enriched text remained almost unknown in e-mail traffic, while HTML e-mail is widely used[citation needed]. Enriched text, or at least the subset of HTML that can be transformed into enriched text, is seen as superior to full HTML for use with e-mail (mainly because of security considerations).[1]

A predecessor of this MIME type was called text/richtext in RFC 1341 and RFC 1521. Neither should be confused with Rich Text Format (MIME type text/rtf or application/rtf) which are unrelated specifications, devised by Microsoft.

A single newline in enriched text is treated as a space. Formatting commands are in the same style as SGML and HTML. They must be balanced and nested.


<bold><italic>Hello, world!</italic></bold>

<italic><bold>Hello, world!</bold></italic>

The following, on the other hand, is not:

<bold><italic>Hello, world!</bold></italic>

The following enriched text:

<color><param>red</param>Blood</color> is <bold>thicker</bold> than

<paraindent><param>left</param><italic>-- Well-known proverb


Blood is thicker than water.

-- Well-known proverb

Enriched text is a supported format of Emacs,[2] Mutt[3] and Mulberry.
