• Looking at the timing, I'm thinking there might have been a recent change to the signup process. Has there been any modification to the free plan signup flow in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, we updated the signup form last week. Impact on approach: If yes, we'd focus on the specific changes made and their potential impact.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 30% drop uniform across all user segments or more pronounced in specific groups?

Why it matters: Helps identify if the issue is global or segment-specific. Expected answer: The decrease is more significant among small business owners. Impact on approach: If segment-specific, we'd tailor our investigation and solutions to that particular user group.

• Given the magnitude of the change, I'm wondering about external factors. Have there been any significant competitor actions or market shifts in the email marketing space recently?

Why it matters: External factors can sometimes explain sudden metric changes. Expected answer: No major competitor actions, but there's been some negative press about email privacy. Impact on approach: If external factors are at play, we'd need to consider both internal improvements and external communication strategies.

• Thinking about data integrity, I want to confirm the reliability of our tracking. Have there been any changes to our analytics setup or known issues with data collection in the past month?
