Case Study: MeUndies achieves 6x return on advertising spend with Facebook

Retargeting Adverts to Underwear Shoppers

MeUndies, a direct-to-consumer underwear brand known for fun, colorful designs, wanted to re-engage shoppers who added items to their online basket but didn’t complete checkout. The challenge was turning abandoned carts into purchases while keeping acquisition costs low.

They installed the Facebook pixel to track add-to-cart events and used Custom Audiences to retarget three recency segments (7, 8–14, 15–30 days) and domestic vs. international shoppers with video, link and carousel ads, A/B testing, and automatic bidding optimized for unique daily reach. The campaign drove a 6x return on ad spend, achieved a cost per action 80% below their acquisition goal, and made Facebook the company’s top source of new customer acquisition.
