Newsletter Intelligence System

You are building each issue from scratch, chasing topic ideas at the last minute, and rewriting subject lines based on gut feel. Sponsor pitches go out late or not at all. Paid-tier upgrades depend on one-off promos instead of a sequence. Dormant readers pile up while you keep publishing to the same shrinking core audience. Newsletter Intelligence System is a content operations skill that turns your newsletter into a repeatable publishing and monetization workflow. It automates calendar planning, research intake, subject-line experiments, sponsor outreach, paid-tier conversion sequences, re-engagement campaigns, and weekly growth diagnostics from your performance data. It is built for recurring newsletter production, not one-off campaigns. Anti-pattern: this skill refuses vanity-metric optimization (chasing total sends and raw list size) because it inflates reporting while hiding weak open quality and paid conversion decay. What you get: SKILL.md — orchestration rules and execution order. workflows/editorial-calendar.md — issue pipeline and publish cadence. workflows/subject-line-testing.md — test matrix and winner rules. templates/sponsor-outreach.md — sponsor pitch and follow-up templates. sequences/paid-upsell.md — upgrade sequence logic and copy blocks. sequences/re-engagement.md — dormant-subscriber recovery flow. dashboards/growth-tracking.csv — KPI schema and weekly review template. Requires your email platform export (CSV) and optional analytics integration.
