Restock Alert: Back-in-Stock and Price-Drop Alerts That Send Themselves
One Shopify widget captures restock subscribers and price-drop watchers. Both alert types fire automatically, recovering revenue you would otherwise lose. Free up to 50 combined alerts, no credit card needed.
How It Works
A clean workflow from sold-out interest to recovered sale.
Add the Widget Block
Open Shopify Admin, customize your theme, and place the Restock Alert block on the product page. One block handles both modes, no extra setup.
Capture Subscribers and Watchers
When a variant is out of stock, shoppers join the restock waitlist. While it's in stock, they can watch for a price drop. The widget switches modes automatically.
Alerts Send Automatically
When inventory returns, restock emails fire instantly. When you lower a price, price-drop emails send the moment Shopify fires the update.
Features
Automated restock capture, alert delivery, and merchant-side visibility, all managed through Shopify.
Back-in-Stock Alerts
Capture demand on sold-out variants and send branded email alerts the moment inventory returns, triggered by Shopify inventory webhooks, no polling.
Price-Drop Alerts
Let shoppers watch a product for a price cut. When you lower the price, they get a branded email showing the strikethrough original price and the new lower price.
Dual-Mode Storefront Widget
One theme app block handles both alert types. It shows the restock form for out-of-stock variants and the price-drop form for in-stock ones, switching automatically.
Fast, Branded Email Delivery
Restock and price-drop emails send immediately when customers are most likely to convert. Per-type message customization keeps each alert on-brand.
Demand Analytics Dashboard
Four stat cards track restock pending, price-drop watching, restock sent, and price-drop sent. See your top waitlisted and most-watched products at a glance.
Consent-Aware, Product-Page Only
A mandatory consent checkbox keeps your signup flow compliance-ready. The widget appears only on product pages, never cluttering collection or home pages.
