Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonality at play. Has this 15% decrease been consistent across all months, or are there specific periods showing more significant drops?

Why it matters: Seasonal patterns could indicate external factors rather than internal issues. Expected answer: The decrease is relatively consistent across months. Impact on approach: If consistent, we'll focus more on internal factors; if seasonal, we'll investigate external influences.

• Considering user segments, I'm curious about the impact across different customer groups. Are we seeing this decrease uniformly across all user segments, or are certain groups more affected?

Why it matters: Segmentation helps identify if the issue is global or specific to certain user types. Expected answer: The decrease is more pronounced in occasional buyers rather than frequent users. Impact on approach: This would guide our focus on re-engagement strategies for specific segments.

• Thinking about recent changes, have there been any significant alterations to the email content, design, or sending frequency in the past year?

Why it matters: Recent changes could directly correlate with the decreased click-through rate. Expected answer: Some minor design changes were implemented, but nothing major. Impact on approach: If changes correlate with the decrease, we'd prioritize reverting or optimizing these changes.

• Considering the broader context, has the definition of "click-through rate" or the system measuring it changed in any way over the past year?

Why it matters: Ensures we're comparing apples to apples and not facing a measurement issue. Expected answer: No changes to the definition or measurement system. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new metrics.
