Rota Sortis helps merchants recover demand from unavailable products and turn customer interest into future sales. When a product or variant is unavailable, merchants can show a storefront widget for waitlists, restock alerts, coming soon states, or native preorders where configured. When stock returns, merchants can send restock emails from a visual Email Studio. The app also supports product bundles, automated discount rules, and demand insights to help merchants decide what to restock first

• Capture waitlists on out-of-stock products with a storefront widget
• Send restock emails from a visual drag-and-drop editor
• Run native preorders with selling plans
