Turn sold-out products
into future sales
Let shoppers join a waitlist for out-of-stock items and automatically notify them the moment stock returns.
Recover sales you would normally lose
When a product sells out, shoppers usually leave and never return. Back in Stock captures that demand and automatically emails customers the moment the item returns — turning a missed sale into a completed one.

How it works
Three steps from signup to sale
Shoppers join the waitlist
When a product is out of stock, a customisable widget appears on your product page. Shoppers enter their email with a single click.
Smart confirmation keeps your list clean
Known Shopify customers are added instantly. New email addresses receive a quick confirmation email — keeping your list spam-free and GDPR-ready.
Back-in-stock emails send automatically
The moment you restock a variant, every confirmed subscriber receives a branded email notification. No manual work required.
A seamless signup experience for your shoppers
The widget drops into your theme as a native block — no code changes. All copy, colors, and placeholder text are customisable from the theme editor.
Notify me when this item is back in stock
Join other shoppers waiting for this item. We'll email you the moment it's available.
No spam. One email when it's back in stock.
See exactly who's waiting and what's selling
Track subscribers by lifecycle status — pending, awaiting restock, or notified. Filter by email or product, and export your full list to CSV in one click.
| Product | Status | |
