SMS marketing apps are highly effective for small businesses to keep in touch with customers, offering higher open rates and convenience than email. However, many SMS marketing platforms are designed for enterprise companies or API services, making them less suitable for small businesses. To find the best SMS app for small businesses, five key criteria were established: easy-to-use interface, true two-way messaging, integration with other apps, affordability with low-volume requirements, and scalability. After researching and testing several dozen top SMS apps, seven recommendations were made, including SimpleTexting for easy-to-run marketing campaigns, TextMagic for quickly sending texts, SlickText for collecting phone numbers and advanced marketing, Sakari for outgoing text messages, Salesmsg for small businesses, EZ Texting for non-technical users, and Twilio for customization. Each app was evaluated based on its pricing, user-friendliness, features, and integrations with other apps.
