<reasoning_process>
1. Determine the ONE thing this email is about: do not dilute with multiple topics.
2. Subject line: 4-7 words that create curiosity or urgency without being spammy.
3. Preview text: the 1-2 lines after the subject in the inbox. Use them strategically, not as an afterthought.
4. Open with value immediately: no 'I hope this email finds you well' filler.
5. Deliver the promised value within the first scroll: if you promised '3 tips,' give them fast.
6. One clear CTA: what exactly should they do after reading?

# Newsletter Issue: [Subject]

**Subject Line Options:**
- A: [Option A — under 50 chars, curiosity or benefit-driven]
- B: [Option B — different angle]

**Preview Text:** [40-90 characters complementing subject line]

---

[Personal, warm opening — 2-3 sentences max. Set the scene or share a quick thought.]

## [Main Content Section]
[Primary article, insight, or story. Make it the reason they opened the email.]
[Use short paragraphs. Subheads for scannability. Keep it conversational.]

## [Secondary Section or Roundup]
[2-3 additional items, links, or brief insights]
- **[Article/Link Title]** — [One sentence on why it matters]
- **[Tool/Resource]** — [Brief context]

[Closing paragraph — personal, brief, forward-looking or reflective.]

[CTA: Clear, single action.]

---

Thanks for reading. [Personal sign-off].
[Your name]

P.S. [Optional PS — often the most-read part. Use for a bonus link, personal note, or secondary CTA.]

<missing_information_rules>
- Subject line: 4-7 words, no ALL CAPS, no excessive punctuation.
- Preview text: use the opening of the email body intentionally.
- Never start with 'I hope this finds you well' or 'Happy [day of week].'
- One primary CTA per email. If you need a secondary link, put it in a P.S.
- Use descriptive anchor text for links (not 'click here').
</missing_information_rules>

<constraints>
- The subject line must earn the open; the first paragraph must earn the read
- One primary CTA — do not dilute with multiple asks
- Total reading time: 3-5 minutes max
- The PS is prime real estate — never waste it
</constraints>

<examples>
<example>
INPUT: Topic: newsletter about user research findings. Audience: product managers. Value: one counterintuitive insight from recent study. CTA: read the full article.

OUTPUT:
Subject: Most user research is wasted
Preview: Here's the one question you should ask instead.

--
Here's a stat that changed how I run research:
80% of feature requests come from power users. But power users are only 10% of your actual users.
You're optimizing for the wrong 10%.
Instead of asking 'what features do you want,' ask:
'What did you try to do this week that you couldn't?'
This one question shift surfaced 3x more actionable insights in our last study.

P.S. The 'couldn't do' question also works surprisingly well in internal stakeholder interviews.</example>
