How Ultimate Gainz Achieved 4× ROAS and Built a 5,000+ Email List
Ultimate Gainz is a European fitness supplements brand selling protein, pre-workout, and performance nutrition products to gym-goers and athletes. We built a combined Meta advertising and email marketing system that achieved 4× ROAS while growing a 5,000+ subscriber email list establishing both acquisition and retention channels simultaneously.
A Supplements Brand Acquiring Customers Without Capturing Long-Term Value
Ultimate Gainz was running Meta campaigns generating one-time purchases, but had no email list or retention infrastructure to capture repeat business a major missed opportunity in supplements, a category defined by recurring purchase behaviour as customers reorder protein and pre-workout monthly.
The European fitness supplements market is intensely competitive on Meta, with established brands driving up CPMs. Without a way to build first-party audience data (email list) for retargeting and retention, Ultimate Gainz was permanently dependent on increasingly expensive cold Meta traffic.
Achieve 3.5×+ ROAS from Meta advertising while simultaneously building an email list of qualified fitness supplement buyers — creating a retention channel that reduces long-term dependency on rising Meta acquisition costs.
Before & After EmergingAds
List-Building Reduces Long-Term Dependency on Rising CPMs
Every email subscriber captured via lead magnet became a retargetable asset independent of Meta's increasingly expensive cold-audience CPMs. Subscribers who entered the email nurture sequence converted to first purchase at a significantly lower blended cost than direct cold-traffic Meta conversion ads.
