Use
You use
wizards when you want to simplify the definition of certain steps within a workflow definition.The number of wizards supplied is increased on a regular basis. Therefore, look in the system to see which wizards are currently available. The wizards are called in the Workflow Builder under Wizards. You can also call the wizard Include "Send mail" from the step type area.

You usually have to process the parts of your workflow definition created by the wizard yourself afterwards. The appropriate explanatory text in the wizard will point this out.
