If a new car model has been launched, the agency owner would want his esteemed list customers to test drive the same. The representative would broadcast a 2way SMS to the chosen list of customers. Those customers who would be interested in booking an appointment for test drive would send back their consent through return SMS. Next, the representative would send invitation to the customers to appear for test drive at designated time. Apart from assured delivery, the relatively inexpensive service can be received and responded to easily.
