Business SMS is text-based communication between businesses and their customers, allowing for two-way conversations and enabling brands to engage with customers in a personalized manner. Businesses use SMS for various purposes such as marketing, customer service, transactional messages, and sales, providing an additional channel to reach customers with higher engagement rates than email. SMS enables real-time conversations and allows brand representatives to interact with customers from a centralized system, making it part of the omnichannel customer experience. By adopting a business SMS strategy, brands can enhance customer engagement and meet customer expectations for personalized experiences.
