StockSentry adds a "Notify me" button and pre-orders through Shopify theme app blocks — no theme code edits, inventory-accurate emails, and flat pricing that doesn't spike when you get busy.
Install on Shopify — free planFree plan available · Pro 14-day free trial · uninstall leaves no code behind
Ships as Theme App Extension blocks you add in the theme editor. No injected scripts, no hidden Add-to-Cart buttons, no "the app broke my theme" — and nothing left behind on uninstall.
Alerts fire from Shopify's own inventory webhooks and check availability at send time. Shoppers only hear about stock they can actually buy.
A real free plan and a flat Pro plan. No per-alert usage caps that quietly turn a $15 app into an $80 bill the month you finally restock.
Take pre-orders on out-of-stock products with a theme block and a clear "Pre-order" line item — demand captured instead of lost.
A most-wanted report shows which out-of-stock products shoppers are asking for — restock the things people actually want.
Support is answered by the person who built it, fast. No ticket purgatory.
