RestockGuard ‑ Stock Alerts

Every sold-out product is lost revenue unless you capture demand. RestockGuard automatically collects customer emails on out-of-stock products and brings them back the moment stock returns. Notify shoppers only when their exact variant is available, improve conversion rates, and recover missed sales with no manual work. Includes built-in pre-order support, revenue tracking, and a fast, no-code setup via Shopify’s theme editor.
