Retention Checklist for Growth Leads
Retention rate: the percentage of customers who make a repeat purchase within a defined period (typically 90 days post-first purchase) relative to the cohort size. For DTC, it's the inverse of churn and the primary driver of unit economics.

Define Your Retention Cohort and Measurement Window
Retention only means something if the cohort and window are fixed. A cohort is a group of customers acquired in the same period (weekly or monthly). The measurement window is how long you wait before counting them retained or churned.
For most DTC Shopify brands, a 90-day window is standard. Some categories (consumables, supplements) use 30 or 60 days. Some (apparel, home goods) use 180 days. The window must match your repeat purchase cycle.
Document your chosen window and cohort grain in a shared spec. Changing it retroactively breaks trend analysis and makes board conversations impossible.
- Cohort grain: weekly or monthly (monthly is standard for brands under $5M ARR)
- Measurement window: 30, 60, or 90 days (match your repeat cycle)
- Exclusions: test orders, wholesale, gift cards (define upfront)
- Repeat purchase = any order after the first, regardless of value
Set Retention Thresholds by Channel and Product
Retention varies by acquisition channel and product category. Email-acquired customers retain at 35-50%. Paid social, 25-40%. Organic, 40-60%. These are not targets - they're diagnostic ranges. If your paid social cohort is at 18%, something is broken in either the acquisition message or the product experience.
Segment retention by product line if you have multiple SKUs or categories. A supplement brand might see 55% retention on subscription products and 28% on one-time purchases. That gap is actionable.
Set a floor threshold: the minimum acceptable retention rate before escalation. For most DTC brands, this is 25-30% at 90 days. Below that, acquisition spend is not profitable at typical AOV and margin.
- Organic / owned channel: 40-60% (baseline high)
- Email acquisition: 35-50%
- Paid social: 25-40%
- Affiliate / influencer: 20-35%
- Floor threshold: 25-30% (escalate if below)
- Segment by product category if AOV or use case differs
Map Retention Drivers and Failure Modes
Retention fails for three reasons: product does not deliver on promise, customer does not know when to reorder, or the reorder experience is frictionless. Diagnose which one is broken.
Product failure: customers receive the item, use it, and don't want it again. This shows up as day-7 to day-30 retention collapse. Audit recent customer feedback, returns, and reviews. If NPS is below 40 or return rate is above 15%, product is the problem.
Awareness failure: customer liked the product but forgot about it or didn't know it was replenishable. This shows up as a flat retention curve after day-30. Check email engagement rates and SMS opt-in. If fewer than 40% of customers are on your email list, you have a capture problem.
Friction failure: customer wants to reorder but the checkout or account experience is broken. This is rare but shows up as a sudden drop in a specific cohort. Audit recent checkout changes, payment processor issues, or shipping delays.
- Product failure: day-7 to day-30 collapse, NPS < 40, returns > 15%
- Awareness failure: flat curve after day-30, email list < 40% of cohort, SMS opt-in < 20%
- Friction failure: sudden cohort drop, checkout errors, payment declines, shipping delays
- Diagnosis: segment retention by acquisition source, product, and geography to isolate
Build the Retention Intervention Checklist
Retention interventions are time-bound and channel-specific. They are not one-time campaigns. They are recurring automations that run against every cohort.
The core sequence: post-purchase email (day 1), product education (day 3-5), first reorder incentive (day 14-21), second reorder incentive (day 45-60), win-back (day 75+). Each step has a specific goal and success metric.
Measure each intervention's lift independently. A/B test subject lines, incentive amounts, and timing. A 2-3% lift on a 30% baseline retention rate is a 6-10% relative improvement and worth the effort.
- Day 1: Transactional + thank you (goal: confirm delivery, set expectations for reorder window)
- Day 3-5: Product education (goal: usage tips, benefits, reorder cycle)
- Day 14-21: First reorder incentive (goal: break inertia, test repeat purchase intent)
- Day 45-60: Second reorder incentive (goal: establish habit, increase LTV)
- Day 75+: Win-back campaign (goal: re-engage churned cohort, measure CAC payback)
- Test each step independently; target 2-3% lift per intervention
Instrument Retention Dashboards and Alerts
Retention is a lagging metric. A 90-day cohort takes 90 days to measure. Build a leading indicator dashboard to catch problems early.
Track day-7, day-14, and day-30 retention for each cohort in real time. If day-7 is below 5%, product or onboarding is broken. If day-14 is flat relative to day-7, your first reorder incentive is not working. If day-30 is below your channel threshold, escalate.
Set automated alerts: if any cohort's day-7 retention is 30% below the previous month's average, flag it. If email engagement (open rate) drops below 20%, flag it. These are early warning signals.
- Dashboard: day-7, day-14, day-30, day-60, day-90 retention by cohort
- Segment by: acquisition channel, product, geography, device
- Alert threshold: day-7 retention 30% below 3-month average
- Alert threshold: email open rate < 20% or click rate < 3%
- Update weekly; review monthly trends in growth meeting
Retention vs. Repeat Purchase Rate - Clarify the Distinction
Retention and repeat purchase rate are often conflated. They are not the same.
Retention rate is cohort-based: what percentage of a cohort acquired in a specific period made a repeat purchase within a defined window. It's backward-looking and stable.
Repeat purchase rate is customer-based: of all customers who have ever purchased, what percentage purchased again in the last 30 days. It's forward-looking and volatile.
Use retention for acquisition and channel analysis. Use repeat purchase rate for cash flow forecasting and inventory planning. Both are necessary.
- Retention: % of cohort with repeat purchase in defined window (e.g., 90-day retention = 32%)
- Repeat purchase rate: % of all customers with purchase in last 30 days (e.g., 28% of customer base purchased last month)
- Retention is stable; repeat purchase rate fluctuates with seasonality and campaign timing
- Use retention for unit economics; use repeat purchase rate for revenue forecasting
Escalation and Ownership
Retention is owned by the growth lead and product lead jointly. Growth owns the intervention sequence and email/SMS execution. Product owns the post-purchase experience and product quality.
If retention falls below threshold, escalate within 48 hours. The escalation should include: which cohort(s) are affected, which failure mode is suspected, and what diagnostic work is underway.
Retention improvements are compounding. A 5% lift in 90-day retention increases LTV by 5-8% depending on repeat order value. This is higher ROI than most acquisition optimizations.
- Ownership: growth lead (email/SMS/incentives) + product lead (experience/quality)
- Escalation trigger: retention below floor threshold for 2+ consecutive cohorts
- Escalation timeline: 48 hours to identify failure mode, 1 week to deploy fix
- Track retention improvements in quarterly business reviews; tie to LTV growth
Questions
FAQ
What's a good retention rate for a DTC Shopify brand?
It depends on category and channel. Consumables (supplements, beauty) typically see 40-60% 90-day retention. Apparel and home goods, 20-35%. Email-acquired cohorts outperform paid social by 10-15 percentage points. Benchmark against your own historical average and your acquisition channel mix, not against a single number.
How do I know if my retention problem is product or marketing?
Segment retention by day. If day-7 retention is below 5%, the product experience or onboarding is broken. If day-7 is healthy (8-12%) but day-30 is flat, your reorder incentive or email sequence is not working. If day-30 is healthy but day-90 is low, you have a habit-formation problem.
Should I offer a discount to drive repeat purchases?
Test it, but measure the incremental margin. A 15% discount that lifts day-30 retention from 25% to 28% is a 12% relative lift, but you're giving up margin on those orders. Calculate the LTV impact: if repeat order AOV is $60 and margin is 40%, a 15% discount costs $9 per order. If the lift is 3 percentage points on a 1,000-customer cohort, that's 30 incremental orders = $270 cost for $720 incremental revenue. Positive, but thin. Test smaller discounts (5-10%) first.
How often should I review retention metrics?
Review leading indicators (day-7, day-14, day-30) weekly. Review full cohort retention (day-90) monthly. Analyze trends and failure modes in your monthly growth meeting. Retention is a lagging metric, so weekly obsession is unproductive, but weekly monitoring catches early signals.
