The Retention System That Turns One-Time Buyers Into Repeat Customers

Retention

Here's a number that should keep you up at night:

The probability of selling to an existing customer is 60-70%. The probability of selling to a new prospect is 5-20%.

Yet most ecommerce brands spend 90% of their budget on acquisition and almost nothing on retention.

Why Retention Matters More Than You Think

A 5% increase in customer retention can increase profits by 25-95%. That's not a typo.

Repeat customers:

  • Spend 67% more than new customers
  • Cost 5-7x less to convert
  • Refer more new customers
  • Are more forgiving of mistakes

The Retention Stack

Email Sequences

Not newsletters. Strategic, automated sequences:

Post-Purchase Flow: Thank you → Usage tips → Review request → Cross-sell. Timed to the product lifecycle.

Win-Back Flow: Triggered when a customer hasn't purchased in X days. Personalized based on their last purchase.

VIP Flow: For your top 10% of customers. Early access, exclusive offers, personal touches.

SMS

Email open rates are declining. SMS open rates are 98%.

Use SMS for:

  • Shipping notifications (builds trust)
  • Flash sales (urgency)
  • Restock alerts (convenience)
  • Birthday offers (personal touch)

Loyalty Programs

Not points-for-purchases schemes. Structured programs that reward behaviors you want to incentivize: referrals, reviews, social sharing, repeat purchases.

The Compounding Effect

When retention works, everything gets better:

  • CAC effectively decreases because LTV increases
  • You can afford to spend more on acquisition
  • Revenue becomes more predictable
  • Growth compounds instead of plateauing

Building the System

This isn't about sending more emails. It's about building a system where every customer interaction is intentional and moves toward the next purchase.

That's what separates brands that plateau at $50k/month from brands that break through to $500k/month.
