This integration eliminates data silos and creates seamless customer journeys that drive both retention and revenue growth.
Wishlist Core Functionality
Mage Loyalty's wishlist features are built for flexibility and convenience. Customers can create multiple wishlists, organizing items by occasion, preference, or category. The platform supports guest wishlists, allowing unregistered shoppers to save items without immediate account creation—lowering friction and capturing interest earlier in the customer journey. Wishlists are fully shareable across social channels and email, amplifying organic reach and social proof.

Re-engagement & Conversion Drivers
Beyond saving, Mage Loyalty implements powerful re-engagement tools that convert wishlist interest into purchases. Automated back-in-stock alerts notify customers the moment a desired out-of-stock product becomes available, recapturing their attention at the critical moment. Price drop notifications keep shoppers informed about discounts on wishlisted items, creating urgency and reducing friction to purchase. The platform includes sophisticated abandoned-wishlist recovery email flows that automatically remind customers of items they've shown interest in—with higher customer retention rates as a documented outcome. Wishlist-triggered emails typically achieve 2-3x higher conversion rates compared to generic promotional emails, making them a high-impact channel for demand generation.
Key Differentiator: Unified Loyalty & Wishlist
Mage Loyalty's most significant advantage is combining an advanced wishlist with a full loyalty program—including VIP tiers, referral programs, and points systems—in a single, integrated platform. This consolidation allows retailers to create holistic engagement strategies where wishlist activity drives loyalty rewards. Customers can earn points for adding items to wishlists or sharing them with others, further incentivizing desired behaviors. The platform offers robust integrations with Klaviyo and Omnisend, ensuring all customer communications—from wishlist alerts to loyalty updates—remain synchronized and personalized. This unified approach reduces operational complexity and marketing overhead compared to managing separate standalone apps. Mage is priced on a flat-rate model ($49–$499/month depending on order volume), with no per-order fees that penalize growth. According to Mage Loyalty, merchants report an average 4x ROI on loyalty program investment and a +15% revenue lift attributed to the loyalty program.
Mage Loyalty is best for Shopify brands looking to consolidate wishlist, loyalty, and referral programs under one roof, seeking to maximize customer lifetime value and streamline marketing efforts with a comprehensive, unified solution.
