Increasing Returning Customer Rate to 53.89% Through a Trust-First Lifecycle Marketing Strategy

What does it take for a supplement brand on Shopify to generate over $800,000 in revenue without increasing ad spend? The answer is a lifecycle marketing strategy built around one fundamental principle: customer trust.

This lifecycle marketing case study breaks down how Moonpie redesigned an underperforming email system into a revenue engine – achieving measurable, sustainable results:

$255,657 USD in email revenue

31,1% of total revenue from email

53,89% returning customer rate

If you are struggling with rising ad costs or underperforming email marketing systems, this framework shows how to turn your existing customer data into a longterm revenue engine.

1. Brand Overview

• Industry: Supplement
• Platform: Shopify
• Lifecycle marketing platform: Omnisend (Email & SMS)

• Product categories:

  • Energy & performance products
  • Hormone balance & longterm wellness products

• Target customer segments:

  • Energy & performance segment
    – Primarily men aged 35+ or individuals working in highintensity environments.
    – They often experience fatigue, lack of focus, and reduced physical performance.
    – They are looking for solutions to improve energy while remaining safe and nondependent on stimulants.
  • Hormone & longterm health segment
    – Primarily women aged 40+.
    – They begin to experience hormonerelated issues affecting mood, physical condition, and overall wellbeing.
    – They prioritize stability, balance, and longterm quality of life.

Key insight: Customers in both segments are not easily convinced by advertising. They need to understand the product clearly before making a purchase decision. This is the core challenge that lifecycle marketing was designed to solve.

2. Key Challenges

2.1. Performance Metrics

From late 2024 to early 2025:

$487,833 total revenue

$58,776 emailattributed revenue

12.05% revenue contribution from email

2.2. System Limitations

• ~68% of revenue came from campaigns
• Only ~32% came from automated flows

This indicates that the automation system was underdeveloped. Key issues included:

• Flows were basic and limited
• No structured postpurchase nurturing system
• Campaigns were mostly promotional and salesdriven
• Click rates were low (~0.3–0.5%)

Email was present, but not functioning as a strategic system.

2.3. Customer Behavior Challenges

In the supplement industry, customers often:

• Doubt product effectiveness
• Do not fully understand how the product works
• Require time before making a decision

Without proper educational and trust-building content, they tend to:

• Not purchase
• Not return
• Not build loyalty

The core issue was not a lack of emails. It was the absence of a trust-building system – the foundation of effective lifecycle marketing.

3. Strategic Objectives

Moonpie did not pursue short-term revenue spikes. Instead, the strategy was anchored in three sustainable objectives:

• Increase email revenue contribution
• Improve returning customer rate
• Reduce reliance on promotional campaigns

The ultimate goal was to transform email into a channel that helps customers understand and trust the product – the prerequisite for both first purchase and repeat purchase.

4. Strategy & Execution

4.1. Rebuilding the Email System Around the Customer Journey

The first step was redesigning the entire email architecture based on lifecycle stages rather than send frequency.

Pre-purchase Stage

Content was focused on identifying customer problems (fatigue, low energy, hormonal imbalance), explaining why these issues occur, and introducing solutions grounded in science. The goal was to help customers understand their own situation before introducing the product.

Post-purchase Stage

Moonpie introduced a structured post-purchase nurturing system covering product usage guidance, clear timelines on expected results, and content that reinforces the customer’s purchase decision. This reduced post-purchase doubt, improved the product experience, and created the conditions for repeat purchase.

4.2. Changing the Communication Approach

Instead of saying: “Product helps increase energy”
Moonpie shifted to:

• Explaining what is happening inside the body
• Clarifying the role of each ingredient
• Showing why the product can be effective

Customers no longer feel they are being sold to. They feel they are being informed.

4.3. Building Deep, Value-Driven Email Content

Email content was developed beyond product promotion.

Personalized content tailored to each customer segment

• Men: focused on energy and hormone support
• Women: focused on balance and overall stability
• Performance-focused users: focused on concentration and endurance

Clear, health-focused content

Emails do not simply claim that the product is effective. Instead, they:

• Explain key ingredients
• Clarify how the product works
• Present information in a simple, easy-to-understand way

Customer Stories & Real Experiences

Moonpie incorporated:

• Real customer feedback
• Post-usage experiences
• Specific improvements

This increases credibility and reduces skepticism.

Long-term Trust Building

Content was designed to:

• Reinforce purchase decisions
• Explain the improvement process
• Avoid unrealistic expectations

The goal is to create confidence and encourage continued usage.

4.4. Personalization Based on Behavior

Moonpie did not send the same content to all customers.
Instead:

• Customers receive content based on their interests
• Product buyers receive relevant guidance and recommendations

This makes email more relevant and effective for each individual.

5. Results: What Lifecycle Marketing Delivered

After implementing the strategy, performance improved significantly:

$255,657 USD email revenue

31,1% of total revenue from email

53,89% returning customer rate

$71,35 USD AOV

 

6. Why Lifecycle Marketing Works for Supplement Brands

Through this engagement, Moonpie confirmed a pattern that appears across high-trust, considered-purchase categories: customers do not lack demand. They lack the trust to act on it.

Lifecycle marketing becomes truly effective when it:

• Helps customers understand the product before they purchase
• Addresses doubts and sets realistic expectations after purchase
• Reinforces the purchase decision to reduce churn
• Builds behavioral data that enables ongoing personalization

These are not tactics. They are the foundation of a sustainable growth system – one that compounds over time as customer trust and lifetime value increase together.
