Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent change in the email content or frequency. Has there been any modification to the email template or sending schedule in the last month?

Why it matters: Changes in email content or frequency could directly impact user engagement and unsubscribe rates. Expected answer: Yes, we updated the email template two weeks ago. Impact on approach: If confirmed, this would shift focus to the new template design and content.

• Considering user segments, I'm curious about the distribution of unsubscribes. Are we seeing this increase across all user segments or is it concentrated in specific groups?

Why it matters: Identifying affected segments could reveal targeted issues or user preferences. Expected answer: The increase is more pronounced in our newer users. Impact on approach: This would lead to an investigation of onboarding processes and new user expectations.

• Given the specificity of the 20% increase, I'm wondering about our measurement systems. Has there been any change in how we track or calculate unsubscribe rates recently?

Why it matters: Ensures we're dealing with a real issue and not a measurement anomaly. Expected answer: No changes in measurement systems. Impact on approach: Confirms the need to look at actual user behavior and product changes.

• Considering potential external factors, have there been any significant competitor actions or market changes in the past month that could influence user behavior?

Why it matters: External factors could explain shifts in user engagement independent of our product. Expected answer: No major competitor changes noted. Impact on approach: Focuses our investigation more on internal factors and user experience.
