Executive Summary

Healthy

Field Notes reached 2,847 subscribers this month, up 6.2% from last month. Open rates averaged 24.8% across four sends, with the March 28 issue on financial intelligence performing strongest at 27.1%.

That tracks with a pattern we're seeing: question-format subject lines consistently outperform wrap-ups by 5+ points, which suggests the audience responds to Courtney's diagnostic voice more than summary content.

Readers are clicking through to the Planning to Scale book page more than any other destination (41% of all clicks), which tells us the book launch activity is working as an entry point. Unsubscribes are flat at 0.2% per send, healthy for this list size and cadence.

One thing to watch: the February wrap-up issue pulled a 21.3% open rate and the highest unsub rate of the period (0.29%), reinforcing that recap-style issues underperform and may be worth rethinking.

Generated April 10, 2026 from HubSpot data. Covering Feb 14 to Apr 10, 2026 (4 sends).
