What are back-in-stock notifications?
Back-in-stock notifications are automated emails sent to customers who have expressed interest in an out-of-stock product. When the product becomes available again, these customers receive an alert so they can complete their purchase.
For online stores, this turns a negative experience - finding a product unavailable - into a future sale. Instead of losing the customer to a competitor, you capture their intent and follow up automatically.
Why your webshop needs them
Out-of-stock products are one of the biggest silent revenue killers for webshops. Without a notification system in place, here is what happens:
- Customers leave your store and buy from a competitor
- You have no visibility into which products have unmet demand
- Restocked products sit idle because previous visitors do not return
- You miss valuable data about customer interest and buying patterns
Back-in-stock notifications solve all of these problems. They capture demand, re-engage customers automatically, and give you actionable insights into which products your customers want most.
How do back-in-stock notifications work?
The process is simple and fully automatic once set up:
- Subscribe - A customer visits an out-of-stock product page and enters their email in the "Notify Me" widget.
- Monitor - The system continuously monitors your inventory. When the product variant is restocked, it detects the change instantly via webhooks.
- Notify - Every subscriber for that product receives a personalized email with a direct link back to the product page, ready to buy.
The entire flow runs in the background. No manual work is required from you as a store owner.
