NM - Vendor-specific back-in-stock notifications

We’re running our store as a marketplace, where multiple vendors sell through our website and ship orders from their own locations. When a customer requests a back-in-stock notification for a product, we’d like that alert to be automatically sent to the specific vendor responsible for that item.

Right now, we have no way to notify vendors directly when their products are in demand. Being able to route notifications based on the product’s SKU or assigned vendor email would help us keep them informed and allow them to restock more efficiently. This would save us time and improve the customer experience by reducing delays in getting popular items back in stock.
