If you give your audience the ability to participate through their computers by filling out a form, or mobile phones by texting a shortcode, you can experience more engagement than if you simply handed out materials. Utilizing a channel that most everyone attending already has access to will save you time and money in the long run, while still being able to maintain a personalized touch.
Upon displaying a question in advance, people at home would be able to fill out a form that was linked through your newsletter or landing page with their answer, and on the day of the event, audience members could text their answer to a shortcode. You can place a delay on the entries of those who filled out the form until a specific time, so as to process everyone's answers at once in order to ensure fairness. If the answer is incorrect, they receive an SMS communication indicating it as such. If, however, the answer is correct, they will be sent an SMS indicating that it is correct.
When someone gives you the correct answer, SimplyCast 360 will update the audience member's information in the CRM and add them to a list as having provided the correct answer. At the same time, you can send them another SMS telling them that they have been entered, along with the other providers of the correct answer, into a raffle for a prize.
You can then enter the CRM and select a winner at random from among those who have been added to the list as having given the correct answer, and send the ultimate winner a text message indicating that they've won, and where to pick up their prize.
