Wishalert: Favorites and BIS
Wishlists, guest favorites, back-in-stock alerts, and merchant analytics—with API access.
Wishalert (Favorites and BIS) improves discovery and conversion by giving shoppers a clear way to save products they love — including guest wishlists — and return when they are ready to buy.
Merchants get actionable analytics: revenue attributed to wishlists, engagement trends, average order value, and how wishlist behavior connects to real orders. That helps you merchandise bestsellers, plan campaigns, and prioritize restocks.
Back-in-stock notifications can be sent from your own domain for a branded experience. The app supports email-based alerts and works alongside your existing stack.
Developers benefit from API access (on eligible plans) to sync wishlist data with mobile apps, CRMs, or custom frontends — including integration with Nodus Works: Mobile App for a cohesive omnichannel experience.

Use Cases
A customer likes a product, it is out of stock, they close the page and never return. This scenario repeats every day in Shopify stores. Wishalert closes this gap with two mechanisms: the wishlist and the back-in-stock alert.
The customer adds the product to the wishlist; when it is restocked, an email or SMS is sent automatically. This user is a ready buyer: they visited once, liked the product, and are expected to return. Wishalert ensures this segment is captured, not neglected.
The Revenue Opportunity Wishalert Creates
In the Shopify stores Nodus Works tracks, the conversion rate within 72 hours of a back-in-stock campaign is 3–5x that of standard email campaigns. The reason is simple: the user already showed purchase intent and requested the notification themselves.
This effect is more pronounced in highly seasonal categories (sports, outdoor, limited edition); the segment that receives the alert when the product is restocked sells out within hours.
