The Client’s Story
A premium electric mobility brand originally from Switzerland expanded into the US market with a strong product reputation and growing online demand. The company approached us with one clear goal: to build a retention system that converts high website traffic into repeat customers and predictable revenue.
Challenge
Despite solid sales and strong brand awareness, email and SMS underperformed their potential. Several key flows were missing, list growth was inefficient, and segmentation lacked structure. Pop-ups converted far below industry benchmarks, and the overall design no longer matched the expectations of a premium audience.
The Growth Method
Flow optimization: Added missing Cart Abandonment, consolidated Post-Purchase, and extended Welcome & Browse.
Segmentation: Introduced behavior-based tiers (T1–T4) and ad-hoc segments needed for specific campaigns.
Design overhaul: Mobile-first, dynamic product blocks, interactive CTAs.
List growth: Redesigned pop-ups to improve capture rate.
SMS cadence: Streamlined messaging & reduced overlap with email.
