One of the primary goals of email campaigns is to encourage customers to click through to the website, driving product browsing and purchases. To understand the impact of different designs on the click-through rate (CTR), our team collaborated with the CRM team and conducted A/B testing after identifying our target customers. This study led to improvements in our design system and ultimately boosted sales. Below are examples where we refined our design system based on user research and incorporated more animations, which contributed to a higher CTR.
