Case Study: Yumi Kim achieves exceptional email engagement (61.6% open, 27.3% click) with Emma, Inc.

Yumi Kim - Customer Case Study

Yumi Kim, a New York City women’s apparel brand known for silk prints and playful designs, needed email marketing that matched its aesthetic while driving conversions, mobile engagement, and cleaner subscriber lists. They worked with Emma, Inc., using Emma’s email marketing platform — including automation and lightbox forms — to capture subscribers and deliver on-brand messages.

With Emma, Inc., Yumi Kim launched a 15% off lightbox signup, automated welcome, birthday, and re‑engagement campaigns, plus mobile-optimized, tappable CTAs and social prompts. The results: a 61.6% average open rate, 27.3% click rate, and a 6% lift in average opens after a re-engagement cleanup that removed inactive subscribers and improved list quality.
