Smart texting is a marketing technique that allows businesses to opt customers into receiving promotional texts. Businesses are encouraged to offer customers incentives to join their texting list, such as discounts or free items. Once customers opt-in, businesses can then send weekly text messages to drive revenue. The document claims most businesses see a 100 customer opt-in per month, resulting in 1200 steady customers per year. With an estimated 8-10% response rate to texts, businesses can see a significant increase in revenue without much cost after an initial $100 setup fee. Customers can opt-in immediately by texting numbers displayed in the ad.
