Growth loops, welcome sequences, and monetization readiness for the only audience you actually own.
Disclaimer. Practitioner frameworks; thresholds are ranges, not guarantees. The author runs paid per-click sponsorships on her own list — these are the numbers sponsors actually pay on.
Platform followers are rented; the list is owned. But most creators (and their AI agents) treat the newsletter as a broadcast afterthought: no welcome sequence, no growth loop, monetization guesses based on list size instead of engagement.
The house rule: engagement monetizes; size impresses. A 520-person list at 43% opens out-earns a 10k list at 12%.
