Output 1: Newsletter Excerpt
File: newsletter/newsletter.md
Length: 150-200 words.
Structure:
- Opening line -- Lead with the single most valuable insight from the atoms. Do NOT open with "Hi [name]" or "In this week's issue." Start with the insight.
- Body -- 2-3 short paragraphs (2-4 sentences each). Bold key phrases for scanners. Use contractions and first-person where the voice allows.
- Exclusive feel -- Frame the content as something the reader gets before everyone else: "Before I shared this anywhere else..." or "This one's just for the list."
- Single CTA -- One clear call-to-action at the end. Link text should describe the outcome, not the action ("See the full breakdown" not "Click here").
Rules:
- Short paragraphs (max 3 sentences)
- No walls of text
- Bold 2-3 key phrases
- Exactly one CTA
- Personal, not corporate
Output 2: Subject Lines
File: newsletter/subject-lines.md
Generate exactly 3 subject line variants, each using a different formula.
Variant 1: Number-Driven (+57% open rate lift)
Formula: [Number] [insights/lessons/mistakes] from [topic] that [changed/revealed/broke] [outcome]
Examples:
- "5 insights from content repurposing that doubled my reach"
- "3 mistakes in email marketing that cost me 2,000 subscribers"
Rules: 40-60 characters. Must contain a specific number. Outcome must be concrete.
Variant 2: Question Hook
Formula: Are you [making/missing/ignoring] this [topic] [mistake/opportunity/signal]?
Examples:
- "Are you making this LinkedIn mistake?"
- "Are you ignoring this SEO signal?"
Rules: 40-60 characters. Must be a yes/no question. Should trigger self-doubt.
Variant 3: Curiosity Gap
Formula: [Topic]: what most [audience] get wrong
Examples:
- "Content repurposing: what most creators get wrong"
- "Newsletter growth: what most marketers miss"
Rules: 40-60 characters. Must imply a knowledge gap. No clickbait -- the email must deliver.
Preview Text
For each subject line, generate matching preview text:
- 40-90 characters
- Complements the subject -- does NOT repeat it
- Adds a second reason to open
- Example subject: "5 insights that changed my content game"
- Example preview: "Plus the one tool I wish I'd found sooner."
Output 3: Email Drip Sequence
File: newsletter/email-sequence.md
Generate a 3-email sequence. Each email has: subject line, preview text, body, and CTA.
Email 1 -- Day 0: Immediate Value
Goal: Deliver the best insight instantly. Build trust.
| Element | Spec |
|---|---|
| Subject | Use Number-Driven formula |
| Tone | "Here's what I learned" -- personal discovery |
| Body | 200-300 words |
| Content | Lead with the highest-impact atom. One supporting point. |
| CTA | Soft -- "Reply and tell me if this matches your experience" |
Structure:
- Hook (1 sentence -- the key insight)
- Context (2-3 sentences -- why this matters)
- The insight expanded (2-3 sentences)
- CTA (1 sentence -- reply or read more)
Email 2 -- Day 2: Deeper Dive
Goal: Expand context. Tell a story or share a case study.
| Element | Spec |
|---|---|
| Subject | Use Question Hook formula |
| Tone | "Let me show you what I mean" -- teacher mode |
| Body | 300-500 words |
| Content | Story, case study, or expanded framework from the atoms |
| CTA | Medium -- "Here's the full breakdown" (link to original content) |
Structure:
- Callback to Email 1 (1 sentence -- "Remember when I said...")
- Story or case study (3-4 paragraphs)
- Key lesson distilled (1-2 sentences)
- CTA (1 sentence -- link to original)
Email 3 -- Day 4: Action CTA
Goal: Drive a specific next step. Create gentle urgency.
| Element | Spec |
|---|---|
| Subject | Use Curiosity Gap formula |
| Tone | "Here's exactly what to do" -- coach mode |
| Body | 200-400 words |
| Content | Actionable steps derived from howto/insight atoms |
| CTA | Strong -- specific action with urgency element |
Structure:
- "If you've been following along..." (1 sentence)
- 3-5 concrete steps (bulleted, brief)
- Urgency element ("This week only" / "Before the algorithm shifts" / time-bound)
- CTA (1 sentence -- specific action)
Rules for All Emails
- Short paragraphs: 1-3 sentences max per paragraph
- One CTA per email: Never compete with yourself
- Personal tone: Write like one person to one person. Use "I" and "you."
- 200-500 words per email: Respect inbox time
- No image-heavy layouts: Text-first for deliverability
- P.S. line optional: Use for a secondary hook or human aside
