A Luxury Accessories Brand with Over 40 Years of American Heritage

For over 40 years, this luxury American accessories brand has been selling premium products directly to customers through digital channels. With a strong online presence and a loyal customer base, the brand has built meaningful scale over time through ecommerce.

As the business looked ahead, the focus shifted toward expanding the customer base, strengthening full-price sales, and ensuring that brand-building investments were delivering measurable value in an increasingly competitive ecommerce environment.

To support this next phase of growth, the brand partnered with a marketing agency, which took over the account with a renewed focus on a full-funnel ecommerce strategy.

To validate and measure the impact of these strategic shifts, the brand and its agency partner turned to Sellforte’s Marketing Mix Modeling (MMM).

Validating a New Strategic Direction

When the agency stepped in, the goal was clear: rebalance media investments to increase brand visibility and attract new customers. What the brand needed was trusted, holistic measurement to confirm whether these shifts were delivering real business impact.

With Sellforte’s MMM in place, the agency and the brand gained:

  • Full-funnel transparency, capturing upper, mid, and lower funnel performance
  • Customer segmentation (new vs. returning), showing where growth was coming from
  • Identification of quick wins and longer-term opportunities through Sellforte’s Marketing X-Ray

This gave the team confidence that their strategic changes were working and provided a credible foundation for conversations at the executive level.

Driving Business Results with Data

The impact of the agency’s strategic shift, validated by Sellforte’s MMM, was immediate and measurable:

  • +24% incremental revenue growth, showing more efficiency from the same media investments

  • +16% ROI improvement, proving stronger returns on every marketing dollar spent

  • New customer share increased by 4pp (23% → 27%), signaling meaningful gains in customer acquisition

  • Base sales grew +3% (+$600K USD), strengthening the underlying performance of the ecommerce business

  • Promotions optimized by -11% (-$1.56M USD), supporting a healthier and more sustainable revenue mix

These results highlighted how the right insights could fuel growth while supporting a more sustainable path forward.

Elevating Measurement to the Executive Level

Beyond the performance gains, Sellforte helped elevate how marketing effectiveness was understood and discussed across the organization:

  • CEO-level presentations began incorporating MMM outputs, linking marketing investments directly to business outcomes

  • Top-of-funnel investments increased, backed by validated data rather than platform-level metrics alone

  • Teams moved beyond limited GA4 reporting to a transparent, trusted, and holistic measurement framework
