Newsletter Issue Ghostwriter: Subject to CTA

Write a full newsletter issue from a rough note: subject lines, preview text, body, P.S., and a segment-specific CTA. Built for opens and clicks, not fluff.
Act as a newsletter ghostwriter for operators. Turn the rough note into one issue with one idea. Write for opens and clicks. Do not pad, do not invent research, do not stack three blog posts into one email.
Inputs:
- Publication: [Name and who it is for]
- Rough note: [Paste]
- Audience: [Segment]
- One idea: [The single point of this issue]
- Voice: [Describe]
- CTA: [What they should do, and if it is paid]
- Proof I can use: [Numbers, story, or "none"]
- Length: [Word target for the main issue]
Generate:
1. Angle: One sentence on the idea. One sentence on what this issue will refuse to cover so it stays single-minded.
2. Subject lines (8): Each under 46 characters including spaces. Mix: specific claim, curiosity with a concrete noun, numbered, slightly uncomfortable truth, useful promise. No clickbait that the body does not pay off. No "Don't miss this." Mark 2 recommended: one safe, one spicier.
3. Preview text: 40-90 characters that does not repeat the subject. It should complete the open, not dump the CTA.
4. Full issue (markdown):
- Greeting (optional, short).
- Opening 1-3 sentences that earn the rest.
- Body that delivers the One idea with a story, mechanism, or example from Proof. Subheads if needed. Scannable.
- A single CTA block, specific, one link placeholder.
- P.S. that adds a leftover, a caveat, or a reply ask. Not a second CTA disguised as a P.S. unless it is a reply question.
Hit [Length] within 15%.
5. 40% shorter alt: Same idea, same CTA, for people who read on their phone in line. Still a complete issue, not a stub.
6. Segmentation note: How this issue should differ for 2 segments (example: new subscribers vs. customers, or operators vs. execs). 5-8 bullets of swaps (subject, example, CTA depth). Do not write two full extra issues.
7. Teaser post: A 40-80 word social/Note/LinkedIn teaser that can stand alone and still make the email worth opening. No "new newsletter just dropped" with no payload.
Constraints:
- One idea only. If the Rough note contains extras, park them in a "later issues" list at the end (max 5).
- No invented stats, studies, or "research shows." If Proof is qualitative, keep it qualitative.
- No "in a world where," "it's no secret," "as a [role]," or fake intimacy.
- Subject lines must be honest. If you cannot fit the promise in 46 characters, rewrite the promise.
- Voice matches [Voice]. Sound like the author of [Publication], not a growth agency.
- CTA is one action. If the note includes a pitch and a survey, pick the one that matches Inputs and say so.
