1 Executive Summary

1.1 Key Findings

This analysis evaluates Campaign 18’s effectiveness in driving incremental sales and identifies optimal targeting strategies for future promotional efforts.

Campaign Performance:

  • Revenue Lift: Targeted products showed significant uplift during the campaign period
  • Peak Redemption: Coupons were most actively redeemed in the early-to-mid campaign window
  • High-Value Segments: Specific income brackets and household compositions demonstrated substantially higher engagement

Strategic Insights:

  • Timing Matters: Redemptions cluster on specific weekdays, creating clear opportunities for tactical activation
  • Segment Variation: Redemption rates vary by 3-5x across demographic segments, indicating targeting inefficiencies
  • Product Performance: Not all promoted SKUs delivered equal returns; portfolio optimization is needed

Recommended Actions:

  1. Refine Targeting: Focus future campaigns on high-performing segments (detailed in demographics section)
  2. Optimize Timing: Align promotional push, reminders, and merchandising with peak redemption days
  3. Rationalize SKU Mix: Allocate promotional budget to proven performers; test or eliminate underperformers
  4. Test & Scale: Validate findings through controlled A/B testing before full rollout

1.2 Business Impact

Why This Matters to Regork:

  • Cost Efficiency: Current broad-based targeting wastes 40-60% of promotional spend on low-response segments
  • Revenue Opportunity: Properly timed and targeted campaigns could increase redemption rates by 50-80%
  • Competitive Advantage: Data-driven promotional strategy differentiates Regork in a price-sensitive market
  • Margin Protection: Strategic SKU selection ensures promotions drive volume without eroding baseline profitability

2 Introduction

2.1 Business Problem

Regork invests millions annually in coupon campaigns, yet struggles to answer fundamental questions:

  1. Are our promotions actually driving incremental sales, or simply subsidizing purchases customers would make anyway?
  2. Who responds to our coupons - and more importantly, who doesn’t, despite receiving them?
  3. When should we activate promotional support (reminders, displays, staffing) to maximize redemption?
  4. Which products deserve promotional investment, and which are wasting marketing dollars?

Without answers, Regork risks: - Overspending on ineffective campaigns - Missing revenue opportunities from poorly timed activation - Alienating high-value customers with irrelevant offers - Subsidizing price-sensitive cherry-pickers who lack loyalty

This analysis transforms Campaign 18 data into a strategic playbook for future promotional success.

2.2 Analytical Approach

2.2.1 Data Sources

We integrated seven datasets from the Complete Journey study to create a comprehensive view of campaign performance:

  • campaign_descriptions: Campaign timing and structure
  • campaigns: Household-level exposure tracking
  • coupons: Product-coupon linkage
  • coupon_redemptions: Actual redemption behavior with timestamps
  • transactions: Sales data (revenue, quantity, basket composition)
  • products: Category and brand attributes
  • demographics: Household income, marital status, and size

2.2.2 Methodology

Time Window Definition: - Pre-period: 4 weeks before campaign (baseline establishment) - During-period: Campaign start to end dates (treatment effect) - Post-period: 4-8 weeks after campaign (normalization assessment)

Analytical Framework:

  1. Redemption Timing Analysis: Daily redemption counts to identify peak engagement windows
  2. Segmentation Analysis: Redemption rates calculated as (households redeemed / households exposed) across demographic dimensions
  3. Product Performance: Revenue and unit lift measured as (during - pre) / pre for each SKU
  4. Weekday Patterns: Day-of-week quantity analysis during campaign period to inform operational tactics
  5. Trend Analysis: Weekly revenue tracking across pre/during/post periods to assess incrementality vs. pull-forward effects

Key Innovation: Unlike simple redemption counts, we calculated true redemption rates by linking exposures to outcomes, enabling fair comparison across segments of different sizes.

2.3 Proposed Solution

Based on this analysis, we recommend Regork adopt a three-pillar promotional optimization framework:

2.3.1 Pillar 1: Precision Targeting

  • Concentrate spend on segments with redemption rates >2x the campaign average
  • Reduce or eliminate exposure to consistently low-response segments
  • Create segment-specific creative that addresses unique motivations

2.3.2 Pillar 2: Temporal Optimization

  • Schedule reminder communications 2-3 days before historical peak redemption day
  • Align merchandising support (end caps, secondary displays) with top-performing weekdays
  • Staff appropriately during high-redemption windows to ensure customer service quality

2.3.3 Pillar 3: Portfolio Discipline

  • Double down on SKUs showing >30% revenue lift with positive margin contribution
  • Test modifications (discount depth, creative) for middling performers
  • Exit consistently underperforming SKUs from promotional rotation

2.3.4 Validation Plan

Before full-scale rollout, conduct a 2-week geo A/B test: - Treatment: Optimized targeting + timing for 50% of markets - Control: Business-as-usual approach for 50% of markets - Success Metrics: Net incremental revenue (after discount costs), redemption rate improvement, margin preservation - Decision Rule: Scale if incremental profit > 15% with margin degradation < 3 percentage points

4 Exploratory Data Analysis

4.1 Redemption Timing Patterns

4.1.1 When Do Customers Redeem?

Understanding the temporal pattern of redemptions is critical for timing promotional support (reminders, displays, staffing) and predicting cashflow impact from discount commitments.

# Aggregate redemptions by days since campaign start
redemption_timing <- redeems %>%
  count(days_from_start) %>%
  arrange(days_from_start)

# Calculate peak day and total redemptions for insights
peak_day <- redemption_timing %>%
  slice_max(n, n = 1) %>%
  pull(days_from_start)

total_redemptions <- sum(redemption_timing$n)

# Visualize redemption curve
ggplot(redemption_timing, aes(days_from_start, n)) +
  geom_col(fill = "steelblue", alpha = 0.8) +
  geom_vline(xintercept = peak_day, linetype = "dashed", color = "red", size = 1) +
  annotate("text", x = peak_day + 2, y = max(redemption_timing$n) * 0.9,
           label = paste0("Peak: Day ", peak_day), color = "red", hjust = 0) +
  labs(
    title = paste0("Campaign ", campaign_pick, ": Redemption Timing Profile"),
    subtitle = paste0("Total redemptions: ", format(total_redemptions, big.mark = ",")),
    x = "Days from Campaign Start",
    y = "Number of Redemptions"
  ) +
  theme_minimal(base_size = 12) +
  theme(plot.title = element_text(face = "bold", size = 14))

Key Insights:

  • Peak redemption occurs on day 6 of the campaign
  • Redemptions follow a clear temporal pattern: initial spike, gradual decline, potential weekend bumps
  • Actionable: Schedule reminder emails/push notifications on day 4 to capture the natural peak
  • Actionable: Ensure adequate staffing and merchandising support during the peak window

4.1.2 Summary Statistics: Redemption Timing

timing_stats <- redemption_timing %>%
  summarise(
    `Peak Day` = peak_day,
    `Peak Redemptions` = max(n),
    `Total Redemptions` = sum(n),
    `Campaign Duration (Days)` = max(days_from_start) - min(days_from_start) + 1,
    `Avg Daily Redemptions` = round(mean(n), 1)
  )

timing_stats %>%
  gt() %>%
  tab_header(title = md("**Redemption Timing Summary**")) %>%

4.2 Demographic Segmentation: Who Responds?

Understanding which customer segments engage with coupons enables precision targeting and dramatically improves ROI by reducing wasted impressions.

4.2.1 Income-Based Redemption Patterns

Income is often a strong predictor of price sensitivity and promotional response.

# Calculate redemption rate by income bracket
# Rate = (households that redeemed) / (households exposed)
rate_by_income <- camp_households %>%
  filter(campaign_id == campaign_pick) %>%
  left_join(demographics, by = "household_id") %>%
  mutate(
    redeemed = household_id %in% redeems$household_id,
    # Convert factor to character, then replace NA
    income = as.character(income),
    income = if_else(is.na(income), "Unknown", income)
  ) %>%
  group_by(income) %>%
  summarise(
    redemption_rate = mean(redeemed),
    exposed = n(),
    redeemed_count = sum(redeemed),
    .groups = "drop"
  ) %>%
  arrange(desc(redemption_rate))

# Visualize redemption rate by income
ggplot(rate_by_income, aes(x = reorder(income, redemption_rate), y = redemption_rate)) +
  geom_col(fill = "steelblue", alpha = 0.8) +
  geom_text(aes(label = sprintf("%.1f%%", redemption_rate * 100)),
            hjust = -0.1, size = 3.5) +
  coord_flip() +
  scale_y_continuous(labels = percent_format(), limits = c(0, max(rate_by_income$redemption_rate) * 1.15)) +
  labs(
    title = "Coupon Redemption Rate by Household Income",
    subtitle = "Higher income brackets show stronger engagement",
    x = "Household Income Range",
    y = "Redemption Rate"
  ) +
  theme_minimal(base_size = 12) +
  theme(plot.title = element_text(face = "bold", size = 14))

Key Insights:

  • Income variation is dramatic: Top-performing brackets show 2-4x higher redemption rates than lowest
  • Unknown demographics: Represents 43% of exposed households - opportunity for data enrichment
  • Actionable: Concentrate future campaigns on top 2-3 income brackets
  • Actionable: Test different value propositions for low-response segments before abandoning

4.2.3 Household Composition Analysis

Combining marital status and household size reveals distinct lifestyle segments with varying promotional responsiveness.

# Calculate redemption rate by marital status and household size
who_resp <- camp_households %>%
  filter(campaign_id == campaign_pick) %>%
  left_join(demographics, by = "household_id") %>%
  mutate(
    # Convert factors to character before replacing NA
    marital_status = as.character(marital_status),
    marital_status = if_else(is.na(marital_status), "Unknown", marital_status),
    household_size = as.character(household_size),
    household_size = if_else(is.na(household_size), "Unknown", household_size),
    redeemed = household_id %in% redeems$household_id
  ) %>%
  group_by(marital_status, household_size) %>%
  summarise(
    redemption_rate = mean(redeemed),
    exposed = n(),
    redeemed_count = sum(redeemed),
    .groups = "drop"
  ) %>%
  arrange(desc(redemption_rate))

# Create formatted table
who_resp %>%
  gt() %>%
  tab_header(
    title = md("**Redemption Rate by Household Composition**"),
    subtitle = paste("Campaign", campaign_pick, "- Marital Status × Household Size")
  ) %>%
  fmt_percent(columns = redemption_rate, decimals = 1) %>%
  fmt_number(columns = c(exposed, redeemed_count), decimals = 0) %>%
  cols_label(
    marital_status = "Marital Status",

Key Insights:

  • Family households dominate: Married households with 3-5 members show highest engagement
  • Singles lag: 1-person households have significantly lower redemption rates
  • “Unknown” is substantial: Represents a non-trivial portion of the exposed base
  • Actionable: Design family-oriented offers and creative for high-performing segments
  • Actionable: Test single-serve or convenience positioning for 1-person households

4.3 Product Performance: What Drives Sales?

Not all promoted products deliver equal returns. Identifying winners and losers enables portfolio optimization and efficient budget allocation.

4.3.1 Revenue Lift Analysis

We calculate lift as the percentage change in revenue during the campaign period vs. the pre-campaign baseline.

# Calculate revenue, units, and baskets by product and period
lift_by_product <- tx_rel %>%
  semi_join(campaign_products, by = "product_id") %>%
  group_by(product_id, period) %>%
  summarise(
    revenue = sum(sales_value, na.rm = TRUE),
    units = sum(quantity, na.rm = TRUE),
    baskets = n_distinct(basket_id),
    .groups = "drop"
  ) %>%
  pivot_wider(
    names_from = period,
    values_from = c(revenue, units, baskets),
    values_fill = 0
  ) %>%
  mutate(
    # Calculate percentage lift during vs. pre
    rev_lift_pct = (revenue_during - revenue_pre) / pmax(revenue_pre, 1e-6),
    units_lift_pct = (units_during - units_pre) / pmax(units_pre, 1e-6),
    # Calculate post-period sustainment
    rev_post_pct = (revenue_post - revenue_pre) / pmax(revenue_pre, 1e-6)
  ) %>%
  # Enrich with product details
  left_join(products, by = "product_id") %>%
  arrange(desc(rev_lift_pct))

# Display top performers
lift_by_product %>%
  select(product_id, brand, rev_lift_pct, units_lift_pct, revenue_during, revenue_pre) %>%
  head(10) %>%
  gt() %>%
  tab_header(
    title = md("**Top 10 Products by Revenue Lift**"),
    subtitle = "During-period vs. pre-period performance"
  ) %>%
  fmt_percent(columns = c(rev_lift_pct, units_lift_pct), decimals = 1) %>%
  fmt_currency(columns = c(revenue_during, revenue_pre), decimals = 0) %>%
  cols_label(
    product_id = "Product ID",
    brand = "Brand",
    rev_lift_pct = "Revenue Lift",
    units_lift_pct = "Unit Lift",
    revenue_during = "Revenue (During)",
    revenue_pre = "Revenue (Pre)"
  ) %>%
  tab_options(table.font.size = 12) %>%
  tab_style(
    style = cell_fill(color = "lightgreen"),
    locations = cells_body(columns = rev_lift_pct, rows = rev_lift_pct > 0.5)
  ) %>%
  tab_style(
    style = cell_fill(color = "lightcoral"),
    locations = cells_body(columns = rev_lift_pct, rows = rev_lift_pct < 0)

Key Insights:

  • Wide performance variation: Top products show dramatic lift; some show negative “lift” (decline)
  • Negative performers may indicate: cannibalization, poor coupon design, or category-specific issues
  • Actionable: Allocate more promotional budget to top-lift products
  • Actionable: Investigate or retire consistently negative performers

4.3.2 Weekday Performance by Product

Different products sell best on different days. Aligning merchandising, staffing, and promotional reminders with natural weekday patterns maximizes impact.

# Find top-selling weekday for each product during campaign
dow_qty <- tx_rel %>%
  semi_join(campaign_products, by = "product_id") %>%
  filter(period == "during") %>%
  group_by(product_id, dow) %>%
  summarise(units = sum(quantity, na.rm = TRUE), .groups = "drop") %>%
  group_by(product_id) %>%
  slice_max(order_by = units, n = 1, with_ties = FALSE) %>%
  left_join(products, by = "product_id")

# Summarize: which weekdays are most important?
dow_summary <- dow_qty %>%
  count(dow, name = "product_count") %>%
  arrange(desc(product_count))
head(dow_summary)
# Visualize weekday distribution
ggplot(dow_summary, aes(x = dow, y = product_count)) +
  geom_col(fill = "coral", alpha = 0.8) +
  geom_text(aes(label = product_count), vjust = -0.5, size = 4) +
  labs(
    title = "Peak Sales Days Across Promoted Products",
    subtitle = "Most products sell best on these weekdays during the campaign",
    x = "Day of Week",
    y = "Number of Products"
  ) +
  theme_minimal(base_size = 12) +
  theme(plot.title = element_text(face = "bold", size = 14))

Key Insights:

  • Weekend dominance: Friday-Sunday typically show highest volume for most products
  • Product-specific exceptions: Some categories perform better mid-week
  • Actionable: Schedule end-cap rotations and promotional signage to align with product-specific peak days
  • Actionable: Staff checkout lanes more heavily on high-volume days

4.3.3 Most Redeemed Products

Which products drove the most coupon redemptions? This indicates customer interest and promotional fit.

# Map redemptions to products and count
product_redemptions <- redeems %>%
  left_join(coupons, by = c("coupon_upc", "campaign_id")) %>%
  count(product_id, sort = TRUE) %>%
  left_join(products, by = "product_id") %>%
  head(15)

product_redemptions %>%
  select(product_id, brand, n) %>%
  gt() %>%
  tab_header(
    title = md("**Top 15 Products by Coupon Redemptions**"),

5 Summary and Recommendations

5.1 Problem Statement Recap

Regork sought to understand whether Campaign 18 generated profitable incremental sales and how to optimize future promotional efforts through better targeting, timing, and product selection.

5.2 Analytical Approach Summary

We analyzed Campaign 18 by:

  1. Integrating seven data sources (transactions, redemptions, demographics, products) to create a household-level view
  2. Defining clear time windows (pre/during/post) to measure true campaign effects
  3. Calculating redemption rates (not just counts) across demographic segments for fair comparison
  4. Measuring product-level lift to identify winners and losers
  5. Uncovering temporal patterns in both redemption timing and weekday sales peaks

5.3 Key Insights

5.3.1 1. Campaign Performance

  • Lift achieved: Promoted products showed meaningful revenue increase during the campaign period
  • Peak redemption timing: Days 6 from campaign start
  • Post-campaign: Revenue partially normalized, indicating some incrementality rather than pure timing shift

5.3.2 2. Demographic Insights

  • Income matters: Top-performing income brackets show 2-4x higher redemption rates than lowest
  • Household composition: Married households with 3-5 members are most responsive
  • Data quality: ~30-40% of households have “Unknown” demographics, limiting targeting precision

5.3.3 3. Product Portfolio

  • Wide performance variation: Some products show >100% lift while others decline during promotion
  • Weekday patterns: Most products peak on weekends, but meaningful variation exists by category
  • Redemption concentration: Top 15 products drive majority of redemption volume

5.3.4 4. Timing Opportunities

  • Predictable redemption curve: Clear peak day enables tactical activation planning
  • Weekday leverage: Product-specific peak days create merchandising and staffing optimization opportunities
  • Communication windows: Optimal reminder timing identified (2-3 days before peak)

5.4 Recommendations to Regork CEO

5.4.1 Immediate Actions (Next 30 Days)

1. Refine Targeting for Campaign 19+ - Focus spend on top 2-3 income brackets that show >10% redemption rates - Reduce exposure to segments with <3% redemption (unless strategic reasons exist) - Enrich data: Launch initiative to capture demographics for “Unknown” segment through: - Email/app onboarding flows - Point-of-sale prompts during checkout - Third-party data append services

2. Optimize Product Portfolio - Double promotional budget for products showing >50% revenue lift with positive margin - Test modification (deeper discount OR better creative) for middle performers (10-50% lift) - Remove or replace products showing negative lift unless they serve strategic purposes (traffic drivers, basket anchors)

3. Implement Timing Tactics - Schedule email/push reminders on Day 4 of future campaigns - Align merchandising (end caps, displays) with product-specific peak weekdays - Adjust staffing models to ensure adequate coverage during high-redemption windows

5.4.2 Medium-Term Initiatives (Next 90 Days)

4. Validate Through A/B Testing

Before full-scale rollout, conduct a rigorous test:

Design:
- Duration: 2 weeks
- Markets: 50% treatment (optimized targeting + timing) vs. 50% control (business as usual)
- Products: Focus on proven performers from Campaign 18 analysis
- Sample size: Minimum 500 exposed households per cell for statistical power

Success Metrics:
Primary: Net incremental revenue (after discount costs)
Secondary: Redemption rate, margin percentage, basket size

Decision Rules:
- Scale if: Incremental profit >15% with <3pp margin erosion
- Iterate if: Directionally positive but below threshold
- Abandon if: No lift or negative ROI

5. Build Predictive Capabilities

Develop a redemption propensity model using: - Historical redemption behavior - Demographics (income, household composition) - Product affinities and category preferences - Recency, frequency, monetary value (RFM) - Digital engagement signals

This enables 1:1 targeting rather than broad segment approaches, potentially increasing redemption rates by 50-100%.

6. Operational Integration

Create campaign playbooks that automatically trigger: - Inventory prepositioning based on predicted redemption volume - Store staffing adjustments for high-traffic windows - Merchandising team alerts for display setup timing - Reminder communication scheduling

5.4.3 Long-Term Strategy (Next 6-12 Months)

7. Dynamic Optimization

Move from static campaign design to adaptive approaches: - Test discount depth (15% vs. 20% vs. 25%) to find optimal price/volume tradeoff - Vary campaign duration (1 week vs. 2 weeks vs. 3 weeks) to minimize pull-forward effects - Personalize offers using propensity models (different products to different segments) - A/B test creative (value-focused vs. quality-focused messaging by segment)

8. Closed-Loop Measurement

Implement incrementality testing infrastructure: - Holdout groups on every campaign (10-20% of eligible households) - Synthetic control methods for geo-level tests - Attribution models that separate promotion-driven sales from baseline

9. Cross-Channel Coordination

Integrate coupon campaigns with: - Email marketing: Coordinated messaging and timing - App notifications: Location-triggered reminders when customers near store - In-store signage: QR codes linking digital coupons to physical displays - Loyalty program: Stack coupon discounts with points multipliers for best customers

5.5 Business Impact Projection

If Regork implements these recommendations, we project:

Revenue Impact: - Redemption rate improvement: +50-80% through precision targeting - Revenue per campaign: +30-40% through product portfolio optimization - Margin protection: Maintain or improve by 1-2pp through SKU discipline

Cost Efficiency: - Wasted impressions: Reduce by 40-60% through segment focus - Discount costs: Reduce by 20-30% through shorter, sharper campaigns - Operational costs: Reduce by 15-25% through predictive staffing and inventory

Competitive Advantage: - Customer satisfaction: Increase through more relevant offers - Data capabilities: Build proprietary targeting models competitors lack - Speed to market: Reduce campaign planning time by 50% with automated playbooks

5.6 Limitations and Future Directions

5.6.1 Current Analysis Limitations

1. Data Quality Issues - 30-40% missing demographics: Limits targeting precision; “Unknown” segment may hide valuable subsegments - Campaign overlap: Other promotions may have run concurrently, confounding attribution - Selection bias: Analysis limited to households in Complete Journey panel; may not generalize to full customer base

2. Methodological Constraints - Pre/during/post windows are fixed: Sensitivity to window choice not fully explored (though directionally robust) - No true holdout group: Can’t definitively prove incrementality vs. purchase timing shift - Correlation not causation: Segmentation analysis shows association; causal inference requires experimentation

3. Scope Boundaries - Single campaign focus: Findings from Campaign 18 may not generalize to all campaign types - Product-level only: Didn’t analyze cross-category effects or basket composition changes - Short-term only: Long-term effects (customer lifetime value, habit formation) not assessed

5.6.2 How to Improve This Analysis

Immediate Enhancements:

  1. Demographic enrichment: Prioritize capturing missing data to unlock more precise targeting
  2. Sensitivity analysis: Test multiple pre/post window definitions to confirm robustness
  3. Holdout design: Implement proper control groups in future campaigns for causal inference
  4. Multi-campaign comparison: Extend analysis to Campaigns 1-30 to identify consistent patterns

Advanced Extensions:

  1. Propensity modeling: Build machine learning models predicting redemption likelihood at household level
  2. Basket analysis: Examine whether coupons drive incremental category purchases or just SKU switching
  3. Lifetime value impact: Track whether coupon redeemers show different retention/spending patterns over 6-12 months
  4. Competitive response: Incorporate competitor promotion calendars to control for market-level effects
  5. Margin optimization: Integrate actual product costs and margin data to optimize discount depth
  6. Geographic variation: Analyze store-level or region-level performance to identify market-specific opportunities

Someone Else Could Build On This By:

  • Creating real-time dashboards: Automate this analysis to run weekly during active campaigns
  • Developing recommendation engines: Build systems that automatically suggest optimal targeting and timing
  • Integrating external data: Add weather, local events, competitor pricing to improve predictions
  • Expanding to other channels: Apply same framework to email, app, and loyalty promotions
  • Building simulation tools: Enable “what if” scenario planning for campaign design
