An email message is made of up of:
Name — The message's name
Subject — The subject of the email/message
Text — The text body of the email/message
HTML — The HTML body of the email/message
The name field is used to identify your message for your internal use, for example: "Newsletter #4 to subscribers," "Newsletter #4 to non-subscribers," and so on. Name, subject, and text are required fields.
In this chapter, we will only discuss the editing and creating of text-only messages; we will discuss HTML editing in Chapter 11.
