# Important Note
**While the values of variables automatically change from one order to another (and some from one driver to another, such as the driver's name), the decision of which variables to use depends entirely on the type of message you would like to communicate to the customer.**
**Therefore, there is no strict or correct answer regarding which variables should or should not be used within a template.**
**However, the recommended best practice is to place the selected variables logically within the free text message so the final message remains clear, professional, and easy for customers to understand.**
