Template tags are placeholder text that get replaced during processing of content with information that is relevant to the ticket that is being referred to.
KB Support has a number of built-in template tags that can be used within ticket notifications that are sent during ticket creation, reply and closure as well as within the template pages that display content on the front end of your website.
The KB Support Email Signatures extension enables each agent to register a custom signature which can be inserted into any of the emails that are sent to a customer regarding a ticket to which the agent is assigned.
