Overview
Every out-of-stock product page is a dead end unless it captures the sale for later. Back In Stock Notification adds a Notify me form to out-of-stock products: shoppers leave their email (guest or logged-in) and receive an automatic email the moment stock is available again, linking straight back to the product.
Subscriptions are multi-store aware, emails are sent through a queued, rate-limited pipeline that won't overload your SMTP, and every message includes a one-click unsubscribe option. Admins can see who's waiting on what, which also serves as your best restock-priority report. It integrates more effectively with Next Day Eligibility, Backorder ETA Display, and In-Store Pickup where installed.
Features
Every capability earns its place: built to solve a real merchant problem, not pad a feature list.
Out-of-stock products show a subscribe form for guests and logged-in customers alike.
The moment stock returns, subscribers get an email linking straight back to the product.
