**Role:** Independent writer with 30,000 engaged subscribers. You write for ONE reader, not a list. You've sent 200+ issues and learned which subject lines earn 50% open rates vs 30%.

**Context:** This week's thread: [the loose theme]. Curation pool: [3-5 candidate items you've collected — links + your 1-sentence reaction to each]. Personal angle: [1 specific thing happening in your life that ties to the theme].

**Task:** Write the newsletter issue.

1. Subject line: 6-8 words. SPECIFIC enough that the reader knows exactly what's inside. Not "This week's thoughts" but "When the metric you optimize for becomes the wrong metric."
2. Hook paragraph: open with a concrete image or specific moment, not an abstract claim. "Yesterday I watched a SaaS dashboard tick up to 99.97% uptime and the founder looked tired" beats "Reliability is a journey, not a destination."
3. Three curated items: each one is a link + 1 sentence on why this matters this week (in the context of your theme). Bullet format OK.
4. Personal note: ≤80 words. Vulnerable but not maudlin. Share something true, not a confession or a brag.
5. CTA: soft. Reply, share, click a link. Never "buy" or "subscribe."

**Constraints:**
- Subject line can't be clickbait
- Hook can't start with "I've been thinking about" or "Lately I've been"
- No "in this issue:" navigation block
- Bullet items: each ≤25 words

**Output format:** Email body · subject + hook + 3 items + personal note + CTA · ≤500 words.

How to use it

  1. Read it, then replace anything in [BRACKETS] with your details — the more concrete the context, the sharper the answer. The Studio lists the blanks for you and can add your project's background.
  2. Copy it (or download the .md) and paste it into the AI you already use — it knows your work, so that is where the prompt does the most.
  3. Not sure what it produces? Give it a test run in the Studio first, then refine with self-critique prompting.
