Sarelly Sarelly Case study

How SarellySarelly connected their Klaviyo-built loyalty logic to a fully branded wallet pass via API — creating a seamless, mobile loyalty experience without duplicating systems.

About

SarellySarelly is a fashion brand that combines strong visual identity with a direct-to-consumer model. With a distinctive tone and a highly engaged customer base, the brand created Casino Sarelly — a loyalty experience designed to feel like an extension of their creative universe. The program is managed through their existing tech stack and reflects the same bold style found across their collections and campaigns.

Challenge

Like many omnichannel brands, SarellySarelly wanted a loyalty solution that would allow them to send push notifications, connect with customers at the point of sale, and offer a consistent mobile experience across channels.

However, what set their case apart was the need to keep full control of the loyalty logic inside Klaviyo. They had already built the structure for earning, burning, and tier progression there — and needed a front-end system that could connect via API, without forcing them to duplicate workflows or adopt a rigid loyalty platform.

Strategy

To bring the experience to life, SarellySarelly implemented JeriCommerce’s API-first wallet pass, connecting Klaviyo’s event and segmentation logic directly to a dynamic pass that customers can use to track their rewards — no app needed.

Klaviyo-powered logic

All loyalty rules and point triggers remain in Klaviyo, while the wallet pass acts as the interactive layer.

Custom integration via API

Custom integration via API

Our platform pulls in real-time updates via endpoints defined by the SarellySarelly team — keeping all backend logic exactly where they wanted it.

Implementation

Through a direct API integration, the JeriCommerce wallet pass became the visual extension of SarellySarelly’s loyalty program. Klaviyo continues to power customer journeys, and every loyalty-related action — from earning points to level changes — is reflected on the pass without delay.

The pass itself is fully branded to reflect Casino Sarelly, reinforcing the experience as part of the larger brand narrative. Customers can access their pass directly from email flows or site touchpoints and see their progress updated in sync with their Klaviyo activity.

"This setup gave us full creative and operational control. We run everything from Klaviyo and let the wallet pass reflect it — no need to compromise our strategy."
— SarellySarelly Team
