The lesson
Turn your own customer data into a newsletter built around charts, each one paired with a plain-English reading.
The issue is titled '4 charts on China vs. the American AI Labs'. A short letter leads to 'OpenAI vs. Anthropic: Anthropic extends gains in enterprise', with a line chart, then a section on open source models opening on 'Key Takeaways' before its line and bar charts. 'So where are we headed' and a grocery-bag photo close it.
Don't borrow the AI topic or Ramp's data; you need a dataset only you hold. Keep the formula: finding-as-title charts, a short takeaway list, and a sign-off that sounds like one person.
