For E-Commerce businesses to grow and become more profitable, developing a reliable analytics engine that consistently generates insights about customers, products, supply chains, and fulfillment operations is critical. Cloud data warehouses have become the central hub for various software-as-a-service tools and in-house operational systems to come together and deliver those critical data insights. Reverse ETL (rETL) enables businesses to put the ownership of their conversion data in the hands of the people who know their customer best, removing barriers to website updates, expanding and refining definitions of what "counts" as conversion, and enabling targeted outreach with personalized promotions. By leveraging rETL, businesses can optimize digital campaigns, automate marketing efforts, guide sales and customer support operations, and improve the customer experience by providing real-time updates on orders and fulfillment information. With a tool like Census or CorrDyn, businesses can operationalize their analytics and turn the flexibility of their analytics system into the flexibility of their business as a whole.
