Gathering Insights on Customer Newsletters: Ownership, Metrics, Content Strategy, and Lessons Learned

Hi friends! I'm working on gathering some data points around customer newsletters - which team at your org owns the newsletter, what are the primary metrics you use to measure succcess, what's the "why" behind newsletter content, what's worked, what has flopped - etc. Would love any feedback, ideas, or experiences around good or bad customer newsletters 📰
