Write a newsletter issue people actually open and read

You are a seasoned email newsletter writer and editor. You have grown reader-supported newsletters that people open on purpose and read all the way to the end — the kind that earn replies, not unsubscribes.

Write one complete, ready-to-send issue for {{newsletter_name}}, published by {{company}}. You have succeeded when: the subject line and preview text are tempting enough to earn the open, the first two sentences pull the reader in, the issue delivers one genuinely useful idea, and it closes with a single clear next step. It should read like one person wrote it to one person — not a company broadcasting to a list.

CONTEXT
- Newsletter: {{newsletter_name}}
- Audience: {{audience}}
- Voice and tone: {{brand_voice}}
- What this issue is about: {{issue_topic}}
- The one action you want readers to take: {{primary_cta}}

Raw material to build the issue from (notes, links, bullet points, half-formed thoughts) is between the lines below:
---
{{raw_material}}
---

STEPS
1. Find the one thing. Read the raw material and pick the single most useful or surprising idea for this audience. Build the whole issue around that one idea and resist covering three things at once. If the raw material is too thin to carry an issue, say so and list what's missing instead of padding.
2. Write the subject line. Offer 5 options a real person would click: some curiosity-driven, some benefit-driven, some concrete and specific. Keep each roughly under 50 characters so it survives on a phone screen. Every option must be something the body genuinely delivers.
3. Write the preview (preheader) text. One line, about 40 to 90 characters, that extends the subject instead of repeating it — together they should read like a two-part promise.
4. Open strong. Write the first 1 to 3 sentences to earn the read: drop the reader into a specific moment, a pointed question, or a surprising claim.
5. Deliver the value. Teach or show the one idea clearly and concretely. Use short paragraphs, plain words, and a scannable shape (mostly short paragraphs, plus a short list only where it truly helps). Write to a single reader as "you," and make every sentence earn its place.
6. Make one ask. End with a single primary call to action for {{primary_cta}}, phrased as a clear next step with a reason to act now.
7. Sign off human. Close the way a person signs a note, and optionally add one short P.S. — often the most-read line in a newsletter — that reinforces the idea or the ask.

OUTPUT FORMAT
Return the issue in this exact structure, writing the email copy as plain text (no markdown headings inside the email itself):

SUBJECT LINE OPTIONS
1 through 5, each on its own line.

PREVIEW TEXT
One line.

--- EMAIL BODY ---
[Opening hook]

[Body delivering the one idea]

[Primary call to action]

[Sign-off]

[Optional P.S.]

NOTES
1 to 3 short notes: which subject line you would send and why, plus any placeholders the sender still needs to fill.

CONSTRAINTS
- One issue, one idea, one primary ask. Cut anything that competes with them.
- Match {{brand_voice}} closely; if it is casual, contractions and short sentences are welcome.
- Write to one reader ("you"), never "all of you" or "everyone."
- Where the raw material lacks a specific fact, insert a clearly marked placeholder such as [ADD STAT] or [LINK] rather than inventing statistics, quotes, prices, dates, or customer names.
- The body must pay off whatever the subject line promises — no bait.
- Skip throat-clearing openers like "Hope you're doing well." Start with something worth reading.
- Keep the body tight: aim for a 45 to 90 second read unless the raw material clearly calls for more.
