We recently launched ShopAgain (shopagain.io) on the Shopify store after successful beta trials (https://www.shopagain.io/case-study).
ShopAgain provides a plug-and-play way for Shopify stores to get their customers back at their store and improve their customer retention. It does not require any technical or marketing expertise to use.
The platform automatically creates personalized segments, emails, SMS, and product recommendation for each Shopify store without any manual intervention required. Your store's data directly powers your campaigns, automations, and flows.
