1. How the Smart options work
Besides custom offers you create yourself, this app has Smart Upsell and Smart Cross-sell options that automatically suggests personalized upsell products or cross-sell combos to your customers, based on sales history and customers' behaviors the app collects and analyses.
Note: Once these options are enabled, the app will analyze and generate automatic recommendations for ALL products on your store. To hide some specific products from Smart up-sell and cross-sell's suggestions, please refer to the tip here.
