Mobile marketing is the art and science of advertising your message, brand, or product through cell phone text messages. Each message carries a coupon or advertisement to an opt-in database of your target customers. Each database is created by placing signage at your location, on the web, or in traditional marketing. A client sees a sign and texts a quick code into their phone, and then sends it to your number. Once received, that person is added to your database as a loyal customer wanting more important notifications from you. The best thing is that a message you send to your clients can easily be forwarded from their cell phone to another and so on. Loyal. Viral. Powerful.
