Hey!Scarcity Low Stock Counter vs REZ Back In Stock Notify Mefor Shopify (2026)
Hey!Scarcity Low Stock Counter and REZ Back In Stock Notify Me both address stock management on Shopify stores but take fundamentally different approaches. Hey!Scarcity focuses on creating urgency and driving immediate sales by highlighting limited inventory, displaying stock levels, and setting up countdown timers. It's geared towards merchants who want to leverage scarcity marketing tactics. In contrast, REZ Back In Stock Notify Me is designed to recapture potential sales lost due to out-of-stock items. It enables pre-orders, backorders, and a 'notify me' feature to build waitlists and inform customers when products are restocked. The primary distinction lies in their focus: Hey!Scarcity aims to prevent customers from delaying purchases, while REZ aims to recover sales from customers who are willing to wait for a product to be restocked. Hey!Scarcity works with existing stock levels to urge conversion. REZ works with *missing* stock to build demand and recapture lost revenue. REZ also has the benefit of analytics around item demand that Hey!Scarcity lacks.
