WishList Ninja writes live wishlist data onto every Klaviyo and Mailchimp profile.
Grounded in available product and source data
A typical wishlist heart icon just saves a product to a list sitting inside the store — WishList Ninja is a Shopify wishlist synced to your email platform instead, writing that same save directly onto the shopper's own Klaviyo, Mailchimp, or Omnisend profile.
That sync isn't a single fire-and-forget event either: live profile properties update in real time, including wishlist_count, wishlist_value, a has_active_wishlist flag, and flags for pending price drops or restocks, plus the top 10 saved products with image, name, price, and URL — all directly usable in a segment rule or a dynamic email block.
Seven named flow triggers turn that data into actual revenue moments: Added to Wishlist, Price Drop & Sale, Low Stock, Back in Stock, Saved a Collection, and New in Collection each fire straight into a connected email platform, with configurable thresholds for what counts as a meaningful price drop and low-stock alerts that adapt to high-volume versus limited-inventory items.
A repeat-revenue mechanic is named specifically to address a real gap in typical wishlist apps: once a shopper buys a saved item, it stays on their wishlist rather than disappearing, so a later price drop or restock on something else they saved can still win a second sale from the same customer. Because wishlists are account-backed, every save maps to a real, identified, emailable shopper profile rather than an anonymous browser session.
On technical footprint, the site states the storefront runs on a single script under 12KB served from Shopify's CDN, with no Liquid theme edits required and nothing left behind on uninstall. An analytics dashboard tracks wishlist-attributed revenue and a 'Most Wanted' report for what to restock, and migrating from another wishlist app preserves shoppers' existing saved items via CSV or Shopify metafields. The page reviewed does not specify a limit on the number of saved items per wishlist, worth checking directly for a store with an unusually large catalog.
It goes directly onto the shopper's email platform profile — live properties like wishlist_count and wishlist_value write onto Klaviyo, Mailchimp, or Omnisend in real time, rather than the wishlist staying isolated inside the storefront.
That's the tradeoff the app accepts deliberately — the site frames the marketing upside (a second sale opportunity from the same customer's other saved items) as outweighing the minor clutter of an already-purchased item staying listed.
The site states the storefront runs on a single script under 12KB with no Liquid theme edits, framed specifically as adding negligible weight to page load compared to a heavier theme integration.
They carry over rather than being lost — migration from another wishlist app is supported via CSV or Shopify metafields specifically so existing saved items survive the switch.
There's no permanent free plan, but every plan includes a 30-day free trial with no charge until day 30, giving a full test window before any payment is required.
Not manually — smart thresholds adapt low-stock alerts to whether an item is high-volume or limited inventory, and a merchant sets what percentage counts as a meaningful price drop rather than a single fixed rule for every product.
