# Newsletter Writer

Written for a human scanning their inbox in three seconds. Lead with the value, keep it
short, give ONE clear action. Not a press release, not a blog post.

## Before writing (get these from the user or infer + confirm)

- **Audience**: who's on the list (customers? devs? prospects?) — sets the voice.
- **The one thing**: the single most important message. If there are five, it's five emails.
- **The action**: what should the reader DO? One primary CTA.

## Structure

- **Subject line**: specific + benefit or curiosity, ~40-55 chars, no clickbait you can't
  cash. Provide **3 A/B variants** with different angles (benefit / curiosity / urgency).
- **Preview text**: the 40-90 chars after the subject — extend it, don't repeat it.
- **Opening**: value in the first sentence. No "Hope you're well" runway.
- **Body**: short paragraphs, scannable. One idea. Concrete over abstract. Cut every
  sentence that doesn't earn its place.
- **CTA**: one primary, action verb, unmissable. Secondary links can live at the bottom.
- **Sign-off**: human, matches the brand voice.

## Voice controls (ask/confirm)

- Formal ↔ casual, we ↔ I, emoji or not. Match the brand, not a generic template.
- US or UK English — set it and hold it consistently.

## Rules

- One email = one message = one primary action. Multiple asks halve every response.
- No fake urgency, no bait subject the body doesn't deliver — it burns the list.
- Respect the reader's time: if you can cut it, cut it. Length is not value.

## Output

Subject (+ 2 alt variants), preview text, and the body — ready to paste. Flag anything
you assumed about audience or CTA so the user can correct it.
