Hey @GV123 

here is what I suggest

Use Klaviyo's Analytics and Reporting

• Navigate to "Analytics" and then "Reports."
• Create or view historical reports on list growth, unsubscribes, and engagement.
• If Klaviyo does not provide a clear historical view through its dashboard, you may need to export historical reports.
• Go to "Lists & Segments" and select the relevant list.
• Use the "Export List" feature to export data periodically (e.g., monthly).

compare all these numbers in a spreadsheet etc to get better idea

Analyze Historical Data

• Campaign Performance Review: Review the performance of individual email campaigns. Identify campaigns with high unsubscribe rates or low engagement.
• List Health Check: Conduct a list health check to identify inactive or low-engagement subscribers. Consider a re-engagement campaign to win back inactive subscribers.
• Content Analysis: Evaluate the content of your emails. Is it relevant and valuable to your audience? Survey your audience to understand their preferences and interests.
• Acquisition Strategy Review: Review your subscriber acquisition strategies. Are you reaching the right audience? Ensure that you have strong calls-to-action and incentives for new subscribers.
• Suppression Reasons Analysis: Deep dive into the suppression reasons to understand if there's a pattern. Address any issues such as frequent hard bounces or high spam complaint rates.

I hope this helps

cheers
