Order confirmation didn't utilize the high-value real estate to educate our customers of one of Zulily's best offer, free shipping after your first order. This project was requested at the end of the year right before the holiday season to get the most demand impact. I had a short concept window to come up with a design, test it, iterate, and release the deliverables to the development team. After it was all complete, we went from pencil and paper to development in under 3 weeks. The new design has increased our click through rate on our shipping offer and resulted in a sustained demand lift even after the holiday season.
