Background

Four Sigmatic, a pioneer in functional mushroom-based wellness products, has carved out a distinctive niche in the health and wellness market. Rooted in Nordic tradition and committed to mental performance and holistic wellbeing, the brand had a strong mission and loyal customer base. Despite its powerful story and high-quality offerings, Four Sigmatic faced a challenge common to fast-scaling DTC brands: customer retention. Their existing email infrastructure lacked the educational depth and personalization needed to nurture long-term loyalty and introduce customers to the full breadth of their product catalog. As a result, churn rates remained higher than ideal, and cross-sell opportunities were underleveraged.

Approach

We began by rearchitecting the brand’s entire lifecycle automation framework, prioritizing education, retention, and product discovery. Our strategy centered on delivering value beyond the initial purchase — turning every email into an opportunity to deepen the customer relationship. This included implementing a rich post-purchase experience that guided new buyers through product benefits, usage tips, and wellness routines tied to their recent order. At the same time, we developed smart segmentation logic that identified repeat buyers, high-LTV customers, and churn-risk profiles. From there, we launched targeted flows to introduce complementary products, seasonal blends, and limited-edition offerings. Each message was fine-tuned to match the brand’s thoughtful voice, combining scientific insight with simple, approachable guidance.

Results

The new system delivered a 61% increase in flow revenue, driven by smarter automation and more meaningful post-purchase engagement. Customers were not only more likely to return — they also explored new products across the catalog, increasing average order values and reducing reliance on first-purchase revenue. By turning email into a personalized educational journey, Four Sigmatic deepened its impact and strengthened its mission to help customers feel their best — one mushroom-powered cup at a time.
