All Templates have three sections: Settings, Subject and Text
Each section is controlled by a set of variables that can be broken down in to two categories:
Settings and Macros
A Setting variable controls either a delivery response setting or modifies the content of a message.
The Settings section of a Template does not use, nor should it reference, a Macro variable and must only use and reference Setting variables.
A Macro variable is an inserted value to control, modify and specify the output of a message. These variables are used in the Subject and Message templates.
The Subject and message sections of a Template should not use, nor should they reference, any Setting variables and must only use Macro variables.
