SMS are typically sent person-to-person, but they are also sent business-to-person. Businesses typically send text messages programmatically. When a business sends a text message to a customer, it tends to be a one-way SMS.Businesses can also send two-way messages to customers when they want to receive a response that provides them with actionable next steps. For example, Pizza offer use case, the outbound message to the customer could include an option to respond "yes to ‘confirm’ ". The customer text response would come back to the Pizza app, and they can then take action based on the response.
