SMS marketing is an effective channel for businesses with a high open rate of 98% compared to email's 14.5%. Consumers are increasingly interested in receiving texts from brands, and SMS is considered valuable by customers who appreciate reminders, updates, and discounts. However, there are some downsides to SMS marketing, such as message length limits, smaller lists, less frequency, and the need for personalization. Businesses can use SMS marketing for various purposes like offering coupons and discounts, providing updates, customer support, hosting contests, conducting polls, and sending newsletters. Twilio offers a free account to get started with SMS marketing and provides an easy-to-use drag-and-drop visual builder called Twilio Studio for creating personalized experiences tailored to customers' needs.
