What it does

Email Write is an agent skill from AgriciDaniel/claude-email. Compose high-converting emails using proven copy frameworks (PAS, AIDA, BAB, FAB, 4Ps). Generates subject line variants with scores, responsive HTML templates with dark mode support, plain-text fallback, and preheader recommendations. Optimized for cold outreach, newsletters, product launches, promotions, and transactional emails. Adapts to user context from email-profile.md.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Newsletters, Product launch strategy and Cold outreach. The repository describes itself as: AI-powered email management and marketing skill for Claude Code. Inbox triage, composition, quality review, deliverability audit, automation sequences, and marketing strategy. The licence is MIT.

When your agent uses it

  • Tasks that involve Newsletters
  • Tasks that involve Product launch strategy
  • Tasks that involve Cold outreach

Example prompts

  • “/email-write”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Grep, Glob

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Gather Context
  2. Select Copy Framework
  3. Generate Subject Lines
  4. Write Preheader Text
  5. Compose Email Body
  6. Generate HTML Version
  7. Generate Plain-Text Version
  8. Output Format

What it can do on your machine

Read from SKILL.md and the folder at commit 182270a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are html and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Email Write loads about 2.8k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 819 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~98
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 PurposeRecommended FrameworkWhy
Cold outreachPASEmpathy-driven, addresses pain points
Product launchAIDABuilds excitement, drives action
NewsletterBAB or AIDAAspirational or engaging storytelling
Feature announcementFABClear value proposition for features
Promotional/saleAIDACreates desire and urgency
Re-engagementPASIdentifies problem of disengagement
Welcome emailBABShows transformation journey
Case study4PsProof-heavy, testimonial-driven
Review requestPASEmpathetic ask for feedback
Appointment reminderDirectNo 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):

CriteriaWeightScoring
Length20100 if 30-50 chars, -10 per 5 chars over/under
Power Words20+20 per power word (max 2)
Personalization25+25 if personalized beyond first name
Spam Triggers-50-50 if contains spam word
Clarity20100 if benefit/topic is clear
Curiosity15+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"
Show full SKILL.md (371 more words)Show less
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:

html
<!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:

markdown
## Email Composition

**Framework**: [chosen framework name]
**Purpose**: [email purpose]
**Tone**: [tone]
**Recipient Type**: [recipient type]

---

### Subject Line Options

| # | Subject | Score | Type | Notes |
|---|---------|-------|------|-------|
| 1 | [subject line 1] | 87 | Curiosity | [why this works] |
| 2 | [subject line 2] | 82 | Benefit | [why this works] |
| 3 | [subject line 3] | 79 | Urgency | [why this works] |

**Recommended**: #1 (highest score)

**Preheader Text**: [30-80 char preheader recommendation]

---

### Email Body (Plain Text)

[Full email body using framework structure]

[Include merge tags like {{firstName}}, {{company}}]

[CTA]

[Signature]

---

### HTML Version

```html
[Complete HTML email code with inline CSS, dark mode support, responsive design]
Plain Text Version
[Plain text fallback with line breaks, CTA as full URL]
Email Metadata
  • Word Count: [body word count]
  • Reading Time: [estimated reading time]
  • Character Count (with spaces): [count]
  • CTA Count: [number of CTAs]
Next Steps
  • Review and edit copy
  • Choose subject line variant
  • Test HTML rendering in email client preview tool
  • Send as draft via MCP (if available) or copy to email platform
  • A/B test subject lines if sending to large list

## Quality Gates

Before delivering the email, verify:

1. **Subject line scores**: At least one variant scores 70+
2. **Preheader length**: 30-80 characters
3. **Framework alignment**: Body follows chosen framework structure
4. **CTA clarity**: Primary CTA is clear and action-oriented
5. **Mobile readability**: Paragraphs are 2-3 sentences max
6. **HTML validity**: Table-based layout, inline CSS, dark mode support
7. **Accessibility**: Alt text on images, plain-text fallback included
8. **Spam check**: No spam trigger words in subject or body
9. **Personalization**: Merge tags used where appropriate
10. **Tone match**: Email tone matches requested tone from profile

If any gate fails, revise before output.

## Error Handling

- If `references/copy-frameworks.md` is missing, warn user and use basic AIDA structure
- If `email-profile.md` is missing, prompt user for context (don't fail)
- If subject line scores are all below 70, generate new variants
- If HTML template fails validation, fall back to plain-text only and warn user

## Resources

- `references/copy-frameworks.md` - Full framework structures and examples
- `email-profile.md` - User's business context and preferences (optional)

## Example Invocation

User: "Write a cold outreach email to a SaaS founder about my SEO audit service"

Agent:
1. Loads email-profile.md (if exists)
2. Selects PAS framework (cold outreach)
3. Generates 3 subject line variants with scores
4. Writes email body following PAS structure
5. Creates HTML template with dark mode
6. Creates plain-text fallback
7. Outputs full email composition with metadata and next steps

## Notes

- This sub-skill focuses on composition only (no sending/scheduling)
- For sending emails, use `email-send` sub-skill or MCP email tools
- For A/B testing, generate multiple variants using different frameworks
- Always adapt tone and complexity to recipient type (B2B vs B2C, technical vs non-technical)
