The goal of retention marketing is to concentrate on your current customer base, while increasing the sales rates and sales volume per purchase. It focuses on current customers only, in order to make sure that they stick to you and become repeat customers. Attracting new customers is important, but keeping your existing ones is essential for any business success in the long term. Mass text messaging and SMS promotions are only available to existing customers because they are subscription based. So if used properly, they can become a powerful tool for increasing customer retention rate. Statistically, mass texting has 98% open and read rates which is substantially higher compared to 22% of emails, 29% of Tweets and 12% of Facebook posts. Another research shows that mass texting service has also a high engagement rate. The click-through rate (CTR) in messages is 10 times higher compared to emails. So clearly mass texting service can play a big role in retention marketing.
