The strategy, segmentation logic, and lifecycle redesign in this case study reflect real work completed for a client. To protect their identity while making the work visible, I created English Boost Club (EB Club) as a fictional brand — including the name, visual identity, and all email copy shown in the mockups. The brand name, design system, and English-language email copy are original work created specifically for this portfolio presentation. The underlying data, metrics, and strategic decisions are real.
