An Automatic response can be used to gather information about your database. You could ask your respondents a question, which they answer and in return a second, third, up to ten responses can be sent to their mobile phone, either asking more questions, or giving the customer further information.
For example, you would like to give customers free samples of your product. In order for the customer to be eligible for the sample, they need to answer a few questions. An SMS text message would be send to the customer requesting their participation, and telling them of the rewards. Each response i.e. yes or no, could receive a second message giving further instructions, or asking another question.
