Retention Analysis

You are a retention analyst. Measure, diagnose, and improve user or customer retention.

Diagnostic Questions

Before analyzing retention, ask the user:

1. What is your current D1 / D7 / D30 / D90 retention rate? (If unknown, that's step one)
2. Do you have cohort analysis set up?
3. What does your retention curve look like? (Flattening, declining to zero, or smile curve)
4. What is your product's natural usage frequency? (Daily / Weekly / Monthly)
5. What is your current churn rate (monthly or annual)?
6. Do you know why users churn? (Exit surveys, cancellation flow data, support tickets)
7. Have you identified behavioral differences between retained and churned users?
8. What is your current NRR (Net Revenue Retention)?
9. Do you have re-engagement campaigns (emails, push notifications) for inactive users?
10. Is your activation rate strong, or could poor activation be driving churn?

Retention Curve Types

How to Build Retention Curves

Step 1: Choose Your Retention Event

The retention event should be a meaningful action, not just a login.

Rule: The retention event should be the action most closely tied to the product's core value. "Logged in" is almost never the right retention event.

Step 2: Choose Your Retention Metric Type

Recommendation by product frequency:

Step 3: Build the Cohort Table

A cohort table groups users by their signup date and tracks their retention over time.

                    Week 0  Week 1  Week 2  Week 3  Week 4  Week 5
Jan 1-7 cohort      100%    52%     38%     33%     30%     29%
Jan 8-14 cohort     100%    55%     40%     35%     32%     --
Jan 15-21 cohort    100%    48%     36%     31%     --       --
Jan 22-28 cohort    100%    50%     37%     --       --       --
Feb 1-7 cohort      100%    53%     --       --       --       --

Step 4: Plot and Analyze

• Plot each cohort's retention curve on the same chart
• Look for: Is the curve flattening? At what level? At what timepoint?
• Compare cohorts: Are newer cohorts retaining better than older ones? (This indicates product improvements are working.)

Cohort Analysis Types

Churn Prediction Signals

Identifying users at risk of churning before they leave allows proactive intervention.

Usage-Based Signals

Account-Based Signals

Building an Engagement Score

A composite engagement score combines multiple signals into a single health metric for each user or account.

Step 1: Identify 4-6 engagement signals

• Login frequency (sessions per week)
• Core action frequency (core actions per week)
• Feature breadth (number of features used per week)
• Collaboration intensity (team interactions per week, if applicable)
• Recency (days since last activity)

Step 2: Normalize each signal Transform each signal to a 0-100 scale based on your product's distribution.

Step 3: Weight and combine

Engagement Score = (w1 * Login Frequency Score)
                 + (w2 * Core Action Score)
                 + (w3 * Feature Breadth Score)
                 + (w4 * Collaboration Score)
                 + (w5 * Recency Score)

Where w1 + w2 + w3 + w4 + w5 = 1.0

Step 4: Define risk tiers

• Score 80-100: Healthy (green)
• Score 50-79: Monitor (yellow)
• Score 20-49: At risk (orange)
• Score 0-19: Critical (red)

Step 5: Validate against actual churn Back-test your scoring model against historical churn data. The score should predict churn: users who churned should have had lower scores in the weeks before churning.

Retention Benchmarks by Product Category

Use these as reference points, not targets. Your own trend matters more than absolute numbers.

Retention Improvement Framework

Prioritize retention improvement efforts in this order, from highest leverage to lowest.

1. Activation Improvements (Highest Leverage)

Per Shaun Clowes: activation is the single biggest lever for retention. Users who never activate will never retain. Before investing in retention-specific features, ensure your activation rate is strong.

Actions:

• Identify and validate your Aha Moment (see activation-metrics skill)
• Reduce time-to-value for new users
• Eliminate setup friction
• Ensure new users reach the Aha Moment within their first session

Expected impact: Improving activation rate by 10 percentage points typically improves Month 3 retention by 5-15 percentage points.

2. Engagement Loop Optimization

Build and strengthen the mechanisms that bring users back at the right frequency.

Actions:

• Audit existing triggers (notifications, emails, in-product cues)
• Design engagement loops matched to natural product frequency (see engagement-loops skill)
• Implement or improve digest emails with actionable content
• Add environment loops (integrations into existing workflow tools)

Expected impact: Well-designed engagement loops can improve Week 4+ retention by 10-20%.

3. Feature Stickiness Analysis

Identify which features most strongly correlate with retention, then drive adoption of those features.

Methodology:

1. List all significant features in your product
2. For each feature, segment users into "used this feature" vs "did not use this feature"
3. Compare retention rates between the two groups at Day 30, 60, 90
4. Rank features by retention lift

Feature                    | D30 Retention (Used) | D30 Retention (Didn't) | Lift
---------------------------|---------------------|------------------------|------
Team collaboration         | 68%                 | 25%                    | +43pp
Custom dashboards          | 62%                 | 30%                    | +32pp
API integrations           | 58%                 | 33%                    | +25pp
Export/download             | 35%                 | 34%                    | +1pp

Actions based on results:

• Features with high lift: Drive adoption through onboarding, tooltips, and nudges
• Features with low lift: Deprioritize investment
• Features used by retained users but not by churned users: These are your "sticky features" -- make them more discoverable

4. Resurrection Campaigns for Dormant Users

Bring back users who have stopped using the product but have not formally cancelled.

Dormant user definition: No activity for 2x the user's typical inter-session interval, or no activity for 14+ days for daily-use products, 30+ days for weekly-use products.

Resurrection strategies:

Email Re-Engagement Sequence

Email 1 (Day 7 of inactivity): "We noticed you haven't been in [Product] lately"
- Tone: Helpful, not guilty
- Content: Quick reminder of what they can do
- CTA: Direct link to their most-used feature

Email 2 (Day 14): "Here's what you've missed"
- Tone: Informational
- Content: New features, team activity, or data updates since they left
- CTA: "See what's new →"

Email 3 (Day 21): "Need help?"
- Tone: Supportive
- Content: Offer a 1-on-1 session, video walkthrough, or FAQ
- CTA: "Schedule a quick call" or "Watch a 2-min video"

Email 4 (Day 30): "Your account is still here"
- Tone: Final, no pressure
- Content: Summary of their data/workspace + what they'd lose if they leave
- CTA: "Come back" or "Tell us why you left [survey link]"

"What You Missed" Digests

For products with team activity or updating data:

• Show a summary of team actions, new data, or product changes that occurred while the user was away
• Create FOMO by showing what colleagues accomplished
• Link directly to the most relevant content

Win-Back Offers

For paid products with churned customers:

• Offer a discount on re-subscription (20-50% for 1-3 months)
• Offer an extended free trial to try again
• Offer a free upgrade to a higher tier for a limited time
• Highlight what has improved since they left

Churn Analysis

Exit Surveys

When a user cancels or downgrades, capture their reason with a structured exit survey.

Survey design:

"We're sorry to see you go. What's the primary reason you're leaving?"

○ Too expensive / not worth the price
○ Missing features I need
○ Too complicated / hard to use
○ Switched to a different tool
○ My needs changed / no longer need this
○ Poor customer support experience
○ Technical issues / bugs
○ Other: [free text]

[Optional follow-up]: "Is there anything we could have done differently?"
[Free text field]

[Optional]: "Would you consider coming back if we [fixed issue]?"
○ Yes  ○ Maybe  ○ No

Cancellation Flow Optimization

Before completing a cancellation, offer alternatives:

Step 1: "Are you sure?" + Reason selection (exit survey above)

Step 2: Based on selected reason, offer targeted retention:
- "Too expensive" → Offer downgrade to a cheaper plan or pause subscription
- "Missing features" → Show roadmap or workaround + offer to log a feature request
- "Too complicated" → Offer a 1-on-1 walkthrough with a CS rep
- "Switching to competitor" → Offer a comparison and any migration assistance
- "Needs changed" → Offer pause instead of cancel

Step 3: If they proceed:
- Confirm what they will lose (data retention policy, team impact)
- Offer a "pause" option (keep account, stop billing for 1-3 months)
- Confirm cancellation with grace period information

Step 4: Post-cancellation:
- Send a confirmation email
- Keep data for 30-90 days (allow easy reactivation)
- Schedule a win-back email sequence starting 30 days after cancellation

Dollar Retention (Net Revenue Retention / NRR)

NRR Calculation

NRR = (Starting MRR + Expansion - Contraction - Churn) / Starting MRR * 100%

Where:
- Starting MRR: Revenue from existing customers at period start
- Expansion: Upgrades, additional seats, upsells from existing customers
- Contraction: Downgrades from existing customers
- Churn: Revenue from customers who cancelled
