Retention Messaging Revamp: Repeat Rate Lift

Context (what was happening)

Repeat purchase rate stalled even as acquisition stayed strong. Post-purchase messaging focused on discounts rather than product use and replenishment.

Constraints (budget, timeline, what couldn’t change)

The team had four weeks and could not increase discount depth. Only email and SMS lifecycle flows were in scope.

Hypothesis (what you believed + why)

We believed that education-led messaging and clearer timing around replenishment would increase repeat rate without eroding margin.

What We Changed (bulleted list)

• Rewrote post-purchase flow to focus on product usage milestones.
• Added replenishment reminders based on average consumption windows.
• Segmented by first-time vs. repeat customers.
• Introduced a soft loyalty nudge after the second order.
• Reduced discount callouts in favor of value-led copy.

The Experiment Plan (5–7 steps)

1. Baseline repeat rate and 60-day LTV for the prior 60 days.
2. Launch new post-purchase flow to 50% of new buyers.
3. Monitor unsubscribe and complaint rates daily.
4. Evaluate repeat rate at day 21 and day 35.
5. Expand to all new buyers once lift is consistent.
6. Apply the flow to existing customers with low repeat history.

Results (table with before/after; use reasonable placeholder metrics)

What Worked / What Didn’t

The biggest gains came from educational reminders tied to actual usage timing. Segmenting first-time customers allowed the team to tailor copy without adding extra sends.

Early loyalty messaging underperformed for one-time buyers and was moved later in the sequence.

Repeatable Takeaways (bullets)

• Lead with value and usage, not discounts.
• Time replenishment nudges to real consumption windows.
• Segment flows by lifecycle stage for better relevance.
• Protect margin by testing incentive depth separately.
