Context Guard

| Context | Status | |---------|--------| | User says "newsletter", "email newsletter", "weekly digest" | ACTIVE | | User says "subscriber growth" or "open rates" | ACTIVE | | User wants to write a newsletter edition or start a newsletter | ACTIVE | | User wants a lead magnet with email capture | DORMANT: use Lead Magnet | | User wants a full content automation pipeline | DORMANT: use Content Pipeline |

Common Mistakes

| Mistake | Why It's Wrong | |---------|---------------| | "Newsletter = company updates" | Nobody cares about your company news. Deliver value: insights, tips, curated content. | | "Generic subject line" | "[Company] Monthly Newsletter" gets 10% opens. Curiosity-driven subjects get 35%+. | | "No consistent format" | Readers want predictable value. A consistent structure builds habit and trust. | | "Too many links" | More than 3-5 links per section dilutes clicks. Feature one primary link prominently. | | "No growth strategy" | "Build it and they will come" doesn't work. Actively promote every issue. |

Protocol

Step 1: Gather Newsletter Requirements

If the user hasn't provided details, ask:

> 1. **Topic/niche**: what's the newsletter about? > 2. **Audience**: who reads it? (role, industry, experience level) > 3. **Frequency**: weekly, biweekly, or monthly? > 4. **Type**: curated links, original essays, tips, industry news, or mixed? > 5. **Current state**: new or existing? (subscriber count, open rates) > 6. **Monetization**: free, paid, or sponsored?

Step 2: Write the Subject Line

**Subject line formulas:**

| Formula | Template | Example | |---------|---------|---------| | **Curiosity gap** | [Topic]: The [thing] nobody talks about | "Pricing: The metric nobody tracks" | | **Numbered value** | [X] [things] to [outcome] this week | "5 tools to ship faster this week" | | **Question** | Why [common practice] [doesn't work / is wrong]? | "Why your landing page isn't converting?" | | **Personal** | I [did thing], here's what happened | "I quit meetings for a month" | | **Direct value** | How to [outcome] (in [constraint]) | "How to write copy that converts (in 20 min)" | | **Current event** | [Event/trend]: What it means for [audience] | "GPT-5: What it means for developers" |

**Subject line rules:**

• 6-10 words (40-50 characters) for mobile display
• No ALL CAPS, no spam triggers ("FREE", "ACT NOW", "!!!")
• Preview text (first 90 characters of email) should complement, not repeat the subject
• A/B test 2 subjects per send (most platforms support this)
• Track open rates by subject formula, double down on what works

Step 3: Design Section Structure

**Newsletter format template:**

# [Newsletter Name]: [Edition Title or Number]

## Intro (2-3 sentences)
[Personal note, context for this edition, or a hook that frames the content]

---

## [Section 1: Primary Content] (60% of newsletter)
[Your main value: original insight, deep dive, or featured piece]
[Include one primary CTA link]

---

## [Section 2: Quick Hits / Curated] (25% of newsletter)
### [Item 1 title]
[1-2 sentence summary + link]

### [Item 2 title]
[1-2 sentence summary + link]

### [Item 3 title]
[1-2 sentence summary + link]

---

## [Section 3: Closer] (15% of newsletter)
[Personal sign-off, question for readers, or community highlight]

---

[Footer: Unsubscribe | Forward to a friend | [Social links]]

**Section type options (pick 2-4 per edition):**

| Section | Content | Purpose | |---------|---------|---------| | **Deep Dive** | Original essay or analysis (500-800 words) | Demonstrate expertise | | **Quick Hits** | 3-5 curated links with one-line summaries | Deliver breadth of value | | **Tool/Resource** | Featured tool with your take on it | Practical value | | **Tip of the Week** | One actionable tactic they can use today | Quick win | | **Community Spotlight** | Reader question, testimonial, or submission | Build community | | **Sponsor Section** | Sponsored content (clearly labeled) | Monetization | | **Poll/Question** | Ask readers something: drives replies | Engagement signal |

Step 4: Write the Edition

**Intro paragraph rules:**

• 2-3 sentences maximum
• Personal and conversational (not corporate)
• Frames why THIS edition matters
• Optional: reference a current event or reader feedback

**Body content rules:**

• Write at an 8th-grade reading level (clear, accessible)
• Use headers, bold, and bullet points for scannability
• One idea per paragraph (3 sentences max)
• Link text should describe the destination ("Read the full case study" not "Click here")
• Primary CTA should appear within the first scroll (above 300 words)

**Personalization techniques:**

| Technique | Implementation | Impact | |----------|---------------|--------| | First name in subject | "Hey {first_name}, [subject]" | +10-15% open rate | | Segment by interest | Tag subscribers → send relevant content | +20-30% click rate | | Reference past behavior | "Since you read about [topic]..." | Higher engagement | | Reader-submitted content | Feature reader questions or wins | Community loyalty |

Step 5: Link Placement Strategy

**Link placement hierarchy:**

| Position | Purpose |
