Email Write Sub-Skill

Purpose

Generate professional, high-converting email copy using proven copywriting frameworks. Produces subject line variants with scoring, responsive HTML templates with dark mode support, plain-text fallback, and preheader recommendations.

Activation

This sub-skill is invoked by the main /email skill when the user needs to compose a new email.

Workflow

1. Gather Context

First, check if email-profile.md exists in the project directory. If yes, load business type, tone preferences, and target audience from the profile.

If no profile exists or user provides new context, ask for:

• Email Purpose: cold outreach, newsletter, product launch, promotional, re-engagement, welcome, feature announcement, etc.
• Recipient: name, role, relationship (new lead, existing customer, subscriber, team member)
• Tone: professional, friendly, casual, authoritative, empathetic, enthusiastic
• Business Type: (from profile or ask) SaaS, e-commerce, service business, agency, creator, B2B, B2C
• Key Message: what action should the recipient take?
• Additional Context: product details, promotion details, deadline, personalization data

2. Select Copy Framework

Based on the email purpose, choose the appropriate framework from references/copy-frameworks.md:

| Email Purpose | Recommended Framework | Why | |--------------|----------------------|-----| | Cold outreach | PAS | Empathy-driven, addresses pain points | | Product launch | AIDA | Builds excitement, drives action | | Newsletter | BAB or AIDA | Aspirational or engaging storytelling | | Feature announcement | FAB | Clear value proposition for features | | Promotional/sale | AIDA | Creates desire and urgency | | Re-engagement | PAS | Identifies problem of disengagement | | Welcome email | BAB | Shows transformation journey | | Case study | 4Ps | Proof-heavy, testimonial-driven | | Review request | PAS | Empathetic ask for feedback | | Appointment reminder | Direct | No framework needed |

If uncertain, default to AIDA for marketing emails or PAS for relationship emails.

3. Generate Subject Lines

Create 3 subject line variants using these strategies:

1. Curiosity-Driven: Creates intrigue, open loop, question, teaser
2. Benefit-Driven: Clear value proposition, outcome, result
3. Urgency-Driven: Time-sensitive, scarcity, FOMO (but not spammy)

Subject Line Rules:

• Optimal length: 6-10 words / 30-50 characters
• Never use ALL CAPS
• Maximum 1 exclamation mark per subject line
• Avoid spam triggers: "FREE!!!", "Act Now", "Limited Time Only", "Guaranteed", "Cash", "No obligation"
• Include personalization where possible (beyond first name: behavior, location, purchase history)
• Use power words: exclusive, secret, insider, proven, breakthrough, transform, discover

Scoring Methodology (0-100):

| Criteria | Weight | Scoring | |----------|--------|---------| | Length | 20 | 100 if 30-50 chars, -10 per 5 chars over/under | | Power Words | 20 | +20 per power word (max 2) | | Personalization | 25 | +25 if personalized beyond first name | | Spam Triggers | -50 | -50 if contains spam word | | Clarity | 20 | 100 if benefit/topic is clear | | Curiosity | 15 | +15 if creates open loop |

Minimum passing score: 70

4. Write Preheader Text

Generate preheader recommendation (30-80 characters):

• Must complement (not repeat) the subject line
• Include secondary value proposition or CTA preview
• Avoid generic text like "View this email in your browser"

Example:

• Subject: "Your personalized SEO roadmap is ready"
• Preheader: "3 quick wins to boost your rankings this week"

5. Compose Email Body

Apply the chosen framework structure. Load full framework details from references/copy-frameworks.md before writing.

General Email Writing Rules:

• Opening: Hook in first sentence, address recipient by name if available
• Body: Use short paragraphs (2-3 sentences max), bullet points for scannability
• Tone: Match requested tone from profile or user input
• Personalization: Use merge tags like {{firstName}}, {{company}}, {{productName}}
• CTA: One primary CTA, clear and action-oriented ("Get Your Free Audit", "Claim Your Spot", "Start Your Trial")
• Social Proof: Include if available (testimonial, stat, case study result)
• Signature: Professional sign-off with name, title, company

Framework-Specific Structure:

Load the full structure from references/copy-frameworks.md and apply. Each framework has:

• Section breakdown (e.g., PAS: Problem → Agitate → Solve)
• Transition phrases
• Example templates

6. Generate HTML Version

Create a responsive, dark-mode compatible HTML email using these specifications:

HTML Template Structure:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta name="color-scheme" content="light dark">
  <meta name="supported-color-schemes" content="light dark">
  <title>{{emailSubject}}</title>
  <style>
    /* Inline critical CSS */
    body { margin: 0; padding: 0; font-family: Arial, Helvetica, sans-serif; }
    table { border-collapse: collapse; }
    .email-container { max-width: 600px; margin: 0 auto; }
    .body-text { font-size: 16px; line-height: 1.6; color: #333333; }
    .cta-button {
      display: inline-block;
      padding: 14px 28px;
      background-color: #0066cc;
      color: #ffffff;
      text-decoration: none;
      border-radius: 4px;
      font-weight: bold;
      min-height: 44px;
      min-width: 44px;
    }

    /* Dark mode styles */
    @media (prefers-color-scheme: dark) {
      body { background-color: #1a1a1a !important; }
      .body-text { color: #e0e0e0 !important; }
      .email-container { background-color: #2a2a2a !important; }
    }

    /* Mobile responsive */
    @media only screen and (max-width: 600px) {
      .body-text { font-size: 14px !important; }
      .headline { font-size: 22px !important; }
      .cta-button { display: block !important; width: 100% !important; }
    }
  </style>
</head>
<body>
  <!-- Email content goes here -->
</body>
</html>

HTML Rules:

• Use table-based layout (not CSS Grid/Flexbox for email client compatibility)
• Max width: 600px
• Inline critical CSS (some clients strip <style> tags)
• Web-safe fonts with fallbacks: Arial, Helvetica, Georgia, Times New Roman
• Minimum 14px body text, 22px headlines on mobile
• CTA button: minimum 44x44px touch target, high contrast ratio (4.5:1)
• Include color-scheme: light dark meta tag
• Dark mode CSS using @media (prefers-color-scheme: dark)
• Alt text on all images (describe content, not "image" or "photo")
• Always include plain-text MIME part for accessibility

CTA Button Best Practices:

• One primary CTA per email (secondary CTAs okay as text links)
• Use <a> tag with role="button" for accessibility
• Padding: 14px vertical, 28px horizontal minimum
• Background color with 4.5:1 contrast ratio against text
• Include fallback for dark mode (lighter background or inverted colors)

7. Generate Plain-Text Version

Create a plain-text fallback with:

• No HTML tags
• Line breaks for readability (max 70 characters per line)
• CTA as full URL on separate line
• Signature block with contact info

8. Output Format

Present the final email composition in this structure:

## Email Composition
