Mage Loyalty

Mage Loyalty is a strategic platform that goes beyond traditional wishlist functionality by seamlessly integrating advanced wishlist features with a comprehensive loyalty and rewards system. This unified approach allows Shopify brands to consolidate customer retention tools into one intuitive platform, creating richer customer experiences while simplifying merchant operations. Rather than managing wishlists, loyalty points, and referrals through separate apps, merchants using Mage gain a single source of truth for customer behavior and engagement data.

Wishlist Core

Mage's wishlist foundation includes multiple wishlist creation, allowing customers to organize saves by occasion, season, or product category. Guest wishlists eliminate friction for first-time visitors, capturing interest before account creation becomes necessary. Easy sharing via email and social channels expands organic reach—when customers share their wishlists, they're effectively promoting your products to their networks. The no-code visual editor means you customize buttons, layouts, and branding without developer involvement, ensuring the wishlist feels native to your store's design language.

Re-engagement

Back-in-stock alerts automatically notify customers when previously saved out-of-stock items return to inventory, creating natural conversion moments. Price drop notifications trigger when wishlist items go on sale, generating urgency. Abandoned-wishlist recovery campaigns surface through Mage's email integrations with Klaviyo and Omnisend, allowing highly personalized re-engagement based on what each customer actually saved. This transforms casual browsing into repeat visit behavior.

Key Differentiator: Combined Wishlist with Full Loyalty Program

What sets Mage apart is its unified architecture. While competitors offer standalone wishlist apps, Mage integrates wishlists with a complete loyalty program including advanced referral programs, VIP tiers, and points systems. Customers earn points not just for purchases but for wishlist interactions—liking items, sharing lists, or completing profile information. This holistic engagement model drives higher lifetime value and stronger repeat purchase behavior.

The platform functions as a strategic customer retention platform, providing unified data that informs both marketing and merchandising decisions. You see wishlist trends alongside loyalty engagement, referral performance, and purchase patterns—all connected. Integration with Klaviyo and Omnisend allows sophisticated segmentation combining wishlist behavior with tier status and referral history, enabling campaigns that feel genuinely personalized.

Mage's flat-rate pricing ($49/month Starter, $499/month Growth) means you never pay per order as you scale. The platform includes Shopify POS support, so wishlists and loyalty work across online and offline channels with unified customer accounts that display loyalty status, wishlist progress, and order history.

Who Mage is Best For

Mage Loyalty is ideal for ambitious Shopify brands consolidating multiple customer retention tools into one platform. Fast-growing stores looking to reduce vendor complexity while maximizing customer lifetime value find Mage's integrated approach particularly valuable. Brands seeking advanced customization without requiring developers benefit from the no-code builders and REST API option. Stores already using Klaviyo or Omnisend for email marketing discover that Mage's deep integrations turn those platforms into powerful loyalty and wishlist extensions.
