WishList Ninja

Most wishlist apps just store saved items. WishList Ninja makes them sell: every save is written onto the shopper's profile in Klaviyo, Mailchimp or Omnisend in real time — including a live has_active_wishlist flag (true only while items are saved), wishlist value and top saved item — so stores can email only shoppers with live buying intent. 7 ready-made flows: price drop, back in stock, low stock + more. 30-day free trial on every plan, unlimited saves. ~12KB script, no code.
