Shopstack Restock Alert App
Shopstack Restock Alert helps Shopify merchants recover revenue from out-of-stock products. When inventory runs out, interested shoppers can subscribe for notifications. The moment products are restocked or prices drop, automated emails bring customers back to complete their purchase — no manual work required.
