Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has this drop coincided with any major holiday or shopping event?

Why it matters: Seasonal trends can significantly impact email engagement. Expected answer: No major holidays or events during this period. Impact on approach: If true, we'd focus more on internal factors.

• Considering the metric specificity, I'm curious about the email open rates. Have they remained consistent, or have they also decreased?

Why it matters: This helps isolate whether the issue is with email delivery/opening or with the deal content itself. Expected answer: Open rates have remained stable. Impact on approach: If true, we'd focus more on the email content and deal attractiveness.

• Given the suddenness of the drop, I'm wondering if there were any recent changes to the email template or deal selection algorithm. Have any such changes been implemented recently?

Why it matters: Recent changes could directly correlate with the performance drop. Expected answer: A new deal selection algorithm was implemented two weeks ago. Impact on approach: If true, we'd prioritize analyzing the new algorithm's impact.

• Thinking about user segments, I'm curious if this decrease is uniform across all user groups or more pronounced in specific segments.

Why it matters: This helps identify if the issue is global or segment-specific. Expected answer: The decrease is more significant among long-time customers. Impact on approach: If true, we'd focus on understanding changes in long-time customer behavior and preferences.
