Adjacent Wellness Email Case Study: 11.5x Revenue Growth in 11 Months
Updated April 26, 2026
Real Klaviyo data from a health & wellness ecommerce brand — not a medspa client. The value for medspas is the transferable retention system: welcome flows, behavioral segmentation, post-purchase nurture, and repeat-revenue automation.
Why Not Natural: Health & Wellness Supplements on Shopify
Why Not Natural is a Shopify-based health and wellness brand selling organic liquid supplements, including adaptogens, collagen, magnesium, B12, and vitamin complexes. Their audience is health-conscious buyers seeking clean, bioavailable formulas.
When they engaged MedspaMarketPro, their email program was generating $1,222/month. They had no automated flows, no behavioral segmentation, and no welcome series beyond a basic coupon email. This is included on MedSpa Market Pro as adjacent wellness proof, not as a medspa-specific case study.
Starting from Near Zero: No Flows, No Segmentation, No Strategy
Email was an afterthought, not a revenue channel. The entire program relied on manual sends with no infrastructure to drive repeat purchases or engage subscribers based on behavior.
- No automated flow infrastructure (all manual sends)
- No behavioral segmentation: every subscriber got the same emails
- No post-purchase sequence to drive repeat orders
- Low subscriber engagement and high churn
- Email contributing less than 3% of total revenue
Building a Behavioral Email Engine, Not a Newsletter
The core insight: most ecommerce brands treat email as a broadcast channel. We built it as a behavioral engine, where every action a subscriber takes triggers a relevant, personalized sequence.
Welcome Series Architecture
Built a 124+ email welcome series covering every product category. Not a drip sequence, but a full education journey. This single flow generated $41,414 in revenue ($1,528 per 1,000 recipients), making it the highest-grossing flow in the entire program.
Behavioral Subflows
Built 10 flows triggered by what subscribers click. Someone opens an email about aging? They enter the Aging subflow. Click on stress? Stress subflow. The result: 73-87% open rates because every email is contextually relevant to what the subscriber cares about.
Abandoned Revenue Recovery
Abandoned cart ($502 per 1,000 recipients), browse abandonment ($1,435 per 1,000 recipients, the highest ROI single flow), and post-purchase ($288 per 1,000 recipients) sequences to capture value at every stage of the customer journey.
Continuous Optimization
Weekly analysis, testing subject lines, offers, and timing. 1,587 emails written over 11 months, each one informed by what worked before. Revenue compounded as more flows went live and data refined targeting.

Month-by-Month Revenue Growth
A note on niche: This is not a medspa client case study. It is adjacent wellness proof from a supplement ecommerce brand. The transferable lesson is the retention framework: segment people by behavior, educate before asking for another purchase or booking, and automate follow-up around repeat-revenue moments. For medspas, the equivalent flows would be new-lead nurture, post-visit rebooking, treatment-package follow-up, membership retention, skincare retail, and abandoned booking recovery.
"The email program became our most reliable revenue channel. It's not just campaigns. It's flows that run 24/7 and convert while we sleep."

This is adjacent wellness proof, not a medspa client case study. The result came from a health and wellness ecommerce brand. The useful takeaway for medspas is the retention framework: welcome sequences for new leads, post-visit sequences to drive rebooking, membership and package follow-up, skincare retail, abandoned booking recovery, and behavioral nurture for prospects who opened but did not convert.
The core infrastructure (welcome series, abandoned cart, post-purchase) takes 4-6 weeks to build and launch. Behavioral subflows are added iteratively over the following months as data comes in. Revenue compounds as more flows go live.
We primarily use Klaviyo for ecommerce and health & wellness brands. For medspas, we work with Klaviyo, Mailchimp, or your existing CRM depending on your tech stack.
