I implemented a promotional popup feature on the Petit Bateau website to display a discount code after a successful newsletter subscription. The popup dynamically generates and shows a personalized promo code, encourages users to check their email (including the spam folder), and provides a direct “Shop Now” button for improved conversion. The design is fully responsive and matches the brand’s visual identity. Confetti animation and smooth transitions were added to enhance user engagement and create a pleasant onboarding experience.
