The only way to get immediate response to advertising campaign is to make sure ALL your target customers actually get the message. Text messaging is the only thing customers check and respond to within 2 minutes of receiving a text message from you.

4pm tuesday night going to get out of work soon. You get a text from Teds pizza, $2.00 off any order for the next 2 hours. Will you stop for pizza on the way home? Very powerful marketing technique!!!!
