What is a back in stock alert?

What a back in stock alert is

When a product sells out, a shop can either show a dead end or ask the shopper to wait. A back in stock alert is the second option. On the sold out product page, the Add to cart button is replaced by something like Notify me or Tell me when it's back. The shopper leaves a way to reach them, usually by being signed in or by typing an email address, and the shop saves the request against that product and, where it matters, the exact size or colour. When stock is added again, the shop works through the list and tells each person. It is a close cousin of a wishlist or favourites list, where shoppers save products they like whether or not they are in stock. The difference is the trigger: a wishlist is something the shopper returns to, while a stock alert is something the shop sends at a specific moment.

How the alert fires when stock returns

The reliable way to send alerts is to tie them to the stock count itself rather than to a person remembering. When an item's stock goes from zero to more than zero, a rule in the database finds every waiting request for that product, creates a notice for each person, and marks the request as notified so nobody is told twice. The notice can go out by email, appear in a notification area on the site or app, or be sent by text, depending on what the shop has and what the shopper agreed to. Good alerts link straight to the product. Where stock is small, some shops tell people in batches, or tell everyone and let the fastest buy, and say so on the page. Afterwards, the list of waiting requests is also useful information: a product with forty people waiting is a strong case for ordering more than last time.

When it is worth adding

Stock alerts pay off for shops that sell out of popular items and restock them, such as small batch makers, fashion sizes, seasonal produce, limited prints and popular books. They are less useful when sold out items never return, because the request turns into a disappointment, or when stock rarely runs out. They also suit made to order businesses that close orders for a while; a waitlist for a product is effectively a stock alert. Consent matters for the channel. An email or text sent because someone asked to be told about one product is expected and welcome, but adding those people to a general marketing list needs separate consent under Australian and UK spam rules. In app notifications avoid that question, since they appear only to signed in shoppers on the site, but they also reach only people who come back to the site and look.

Common mistakes

Letting people sign up for alerts on items that will never return. Alerting on a product but not the specific size or colour, so a shopper waiting for a medium is told when only larges arrive. Sending the alert twice, or days late, because it depends on someone remembering to send it. Adding alert requests to the newsletter list without consent. Showing the number of people waiting in a way that reveals who they are. Telling three hundred people about five items at once without saying stock is limited, then leaving most of them annoyed. Forgetting to remove a request once the person has bought the item. And never looking at the waiting list as data, when it is one of the clearest signals a small shop has about which products to reorder and in what quantities.

Where it shows up in OneCraft

When a site is generated with saved items, the AI builds them into the site's own database from its favourites guide: a heart button on product cards and pages, a Saved page, and on a sold out product a Tell me when it's back button for signed in shoppers, saved per product and variant. A database rule fires when the product's stock goes from zero back up and puts a notice for each waiting shopper in the site's notification bell, marking the request so nobody is told twice. Each shopper can see only their own saved items and alerts, and nobody sees who saved what; admins see how many people are waiting per product. The alert appears in the bell only: the site cannot email these shoppers, pushes to phones are not available, and there is no SMS.
