The last step in the Email Workflow is called "Template" and here the user can create an Email subject as well as create an Email Template with the Template Builder.
The user can add an Email Subject for their emails that will be generated and sent out. The Workflow Tags created in the previous step, can be used in this input field to construct a dynamic email subject that will be applied to all recipients.
The created tags can be used by adding them inside two curly brackets, see example in screenshot.
