Email Personalization for Fashion Retailer

The problem

StyleBrand was sending the same promotional emails to their entire 2M subscriber list. Open rates were declining, unsubscribe rates were climbing, and email revenue had plateaued. They knew personalization was the answer but didn't know where to start with millions of customers and thousands of products.

What we built

We built a personalization engine that determines the optimal content, products, send time, and subject line for each subscriber. The system analyzes browsing behavior, purchase history, email engagement, and seasonal patterns. It generates dynamic email content that's different for each recipient.

Results
