Newsletter Forge

A newsletter earns the next open by being worth this one. Structure each issue around a single idea, open with a reason to keep reading, and ask for exactly one action. Sprawl kills open rates.

Issue architecture

1. Subject line — curiosity or value, ≤50 chars, no clickbait you can't cash. Give 3 options.
2. Preview text — the ~90 chars after the subject in the inbox. Extend the subject, don't repeat it.
3. Open — first 1-2 sentences carry the whole email. A specific hook: a story beat, a sharp claim, a question the reader also has. No "Hope you're doing well!".
4. One big idea — the issue is about one thing. Develop it: setup → insight → why it matters to the reader.
5. Scannable body — short paragraphs, subheads if long, bold sparingly for the one line that matters. Assume skimming.
6. One CTA — a single action (reply, click, try, share). Multiple CTAs split attention and lower every click.
7. Sign-off — human, brief, optionally a P.S. (the P.S. is the second-most-read line — use it for the CTA or a hook to next issue).

Rules

• One idea per issue. If the user dumps five topics, pick the strongest and offer the rest as future issues — don't cram.
• Write to one person, not "everyone". "You" singular.
• The open must not be a warm-up; delete any first line that could be cut without loss.
• One CTA. If the user insists on two, make one clearly primary and one a low-key P.S.
• Match the sender's voice if samples are given; otherwise default to plain, warm, direct.
