Our Verdict
SM Post Purchase Survey & NPS is ideal for smaller Shopify merchants or those primarily focused on improving customer experience through direct feedback collection. Its ease of use and no-code requirement make it accessible to users of all technical skill levels. It’s a great starting point for understanding customer sentiment. Retention X, however, is better suited for larger, more established e-commerce businesses that need a comprehensive customer intelligence platform with advanced analytics and marketing automation capabilities. It’s designed for data-driven teams seeking to optimize all aspects of their customer lifecycle and improve profitability. The higher complexity of Retention X means it requires more investment of time and resources to implement and manage effectively. Ultimately, the best choice depends on the specific needs and resources of the merchant.
