It is a highly targeted form of advertising. You can target your campaigns to specific customers to produce higher redemption rates and build lists that will produce immediate sales every time you send a new text advertisement to them.
Text marketing delivers your message with no filler. Just give the customer what they want, short and direct and they will respond. Text messages are capped 160 characters and give your customers a reason to do business with you without having to decipher what your ad actually is about.
