# /kai-newsletter — An Edition Subscribers Open Twice ## Objective A send-ready newsletter edition: one lead story worth the open, two or three supporting items, one primary CTA, a subject line and preview text that work as a pair, and a segment and send time chosen on purpose. The edition earns the next open — the footer sets expectations for what comes next and when. ## Done when Work type `email-lifecycle` — floor **E5/C3/O3** (`harness/eco-floors.yaml`, contract `harness/skill-contracts/email-lifecycle.yaml`). - **E5** — the ESP reports the send completed with a recipient count reconciled to the approved segment, verified by someone other than the producer. An edition approved in a file is E3. - **C3** — `four_us_score` ≥ **10/16**, zero Tier 1 banned words, no AI slop, and a named non-producer reads the edition end to end. Unsubscribe handling and sender identity are a C4 field-standard item, not a lint pass — check them against `harness/references/advertising-compliance.md` before send. - **O3** — open rate, click rate, reply rate, unsubscribe rate, or revenue per recipient read from the ESP at the 14-day window against a threshold declared before send. ## Constraints - **Subject line:** under 50 characters, no spam trigger words, no ALL CAPS. Generate 5+ candidates and pick with a stated rationale. - **Preview text complements the subject line.** It never repeats it. - **One primary CTA per edition, one secondary at most.** Specific action, not "learn more". - *
