HTML Email and Using Style

General Notes

An Email template is usually sent as a single-part or a
multi-part. There are several MIME types associated with the various
parts, the most common being text/plain, text/enriched and text/html.
The only MIME type on topic for this WIKI is the HTML. This document
addresses CSS that works safely in the majority of cases. If you have
questions about overall email template layouts and syntax, you can
contact ElizabethDavies directly.
