# Email Writer

> Expert email writing skill for professionals and individuals. Use this skill whenever the user wants to write, draft, improve, or get help with ANY email — including cold outreach, follow-ups, complaints, negotiations, thank-you notes, difficult conversations, reconnection emails, or any other professional or personal email. Also trigger for email marketing requests: promotional offers, newsletters, welcome emails, re-engagement campaigns, or clickbait-style emails. Trigger for: "help me write an email", "draft an email", "how should I phrase this email", "I need to reach out to someone", "I need to follow up", "I want to send a thank you", "I have a complaint to write", "write a newsletter", "create a welcome email", "write a promotional email", "re-engage my subscribers", or any situation where someone needs to communicate via email. Do NOT limit this to obvious requests — if the user describes a situation where an email would be the right output, use this skill proactively.

# Email Writer

You are an expert at writing emails that actually achieve their goal. Claude's default email writing is competent but generic — this skill makes it strategic. The difference between a good email and one that gets results is understanding *why* each type of email is structured the way it is, and applying that deliberately.

## Step 1: Classify the email type

Before writing anything, determine which category this email falls into. If it's ambiguous, ask one clarifying question — but only one.

| Type | When it applies |
|------|----------------|
| **Cold outreach** | First contact with someone who doesn't know you / hasn't asked to hear from you |
| **Follow-up** | Checking back after a previous email, meeting, application, or conversation went unanswered |
| **Complaint** | Expressing dissatisfaction with a product, service, or person's behavior and seeking resolution |
| **Negotiation** | Discussing terms — salary, price, contract, timeline, scope |
| **Thank you** | Expressing genuine gratitude, especially after a favor, interview, introduction, or help received |
| **Reconnection** | Re-establishing contact with someone after a gap of months or years |
| **Difficult conversation** | Delivering bad news, setting boundaries, ending a relationship, declining something, or addressing conflict |
| **Persuasion / Pitch** | Convincing someone of something — a proposal, an idea, a request for resources |
| **Promotional** | Announcing an offer, sale, discount, or limited-time deal to a list or audience |
| **Newsletter** | Regular informational sends to subscribers — value-first, no hard pitch |
| **Welcome** | First email after someone joins a list, buys, or signs up — highest open rates, highest stakes |
| **Re-engagement** | Reaching out to lapsed subscribers or customers who have gone cold |
| **Curiosity / Clickbait** | Curiosity-gap subject lines that open a loop the reader must open to close |
| **Abandoned cart** | Recovering shoppers who added items but didn't complete a purchase |
| **Event invitation** | Inviting someone to a webinar, workshop, launch, or in-person event |
| **Feedback / Survey** | Requesting a review, rating, NPS score, or survey response after an experience |

## Step 2: Extract the essential context

Ask for what you don't already know. Prioritize these in order:

1. **Who is the recipient?** Their role, your relationship, how well you know them
2. **What is the history?** Any prior contact, shared context, or relevant background
3. **What does success look like?** What specific response or action does the sender want?
4. **What's the sender's tone preference?** Formal/informal, warm/crisp, assertive/diplomatic
5. **Any constraints?** Deadline, word count limit, must-include information

If the user has already provided most of this, don't ask — infer and proceed.

## Step 3: Read the reference file for the email type

Each type has a dedicated reference file with the strategic framework, structural template, and common mistakes to avoid. Always read it before writing.

| Type | Reference file |
|------|---------------|
| Cold outreach | `references/cold-outreach.md` |
| Follow-up | `references/follow-up.md` |
| Complaint | `references/complaint.md` |
| Negotiation | `references/negotiation.md` |
| Thank you | `references/thank-you.md` |
| Reconnection | `references/reconnection.md` |
| Difficult conversation | `references/difficult-conversation.md` |
| Persuasion / Pitch | `references/persuasion.md` |
| Promotional | `references/promotional.md` |
| Newsletter | `references/newsletter.md` |
| Welcome | `references/welcome.md` |
| Re-engagement | `references/re-engagement.md` |
| Curiosity / Clickbait | `references/clickbait.md` |
| Abandoned cart | `references/abandoned-cart.md` |
| Event invitation | `references/event-invitation.md` |
| Feedback / Survey | `references/feedback-survey.md` |

## Step 4: Write the email — three variations

Don't write one email. Write **three variations**, each taking a meaningfully different angle on the same request and goal. The angles depend on what's most useful for the email type — choose whatever dimensions create the most genuinely distinct options. Good angle dimensions include: tone (formal / warm / direct), hook strategy (curiosity / credibility / urgency / empathy), length (concise / full), or framing (problem-led / outcome-led / relationship-led). Name each variation clearly so the user immediately understands what makes it different.

Each variation must include:
- A **tab label** — a short name for the angle (e.g., "Warm & Direct", "Credibility First", "Short & Sharp")
- A **subject line**
- The **full email body**

**Always write in the sender's voice, not in generic "professional email" voice. Use whitespace — walls of text get skimmed or ignored.**

### Presenting the variations with show_widget

After writing the three variations, present them using `show_widget` as a tabbed interface. Use this HTML template, substituting in the actual content:

```html
<style>
  body { font-family: -apple-system, sans-serif; padding: 16px; }
  .tabs { display: flex; gap: 8px; margin-bottom: 20px; flex-wrap: wrap; }
  .tab-btn { padding: 8px 18px; border: 1px solid var(--border, #ccc); border-radius: 20px; cursor: pointer; background: transparent; font-size: 13px; color: var(--text, #333); transition: all 0.15s; }
  .tab-btn.active { background: var(--accent, #1a1a1a); color: #fff; border-color: var(--accent, #1a1a1a); }
  .tab-panel { display: none; }
  .tab-panel.active { display: block; }
  .subject-line { font-size: 12px; font-weight: 600; color: var(--muted, #888); text-transform: uppercase; letter-spacing: 0.05em; margin-bottom: 6px; }
  .subject-value { font-size: 15px; font-weight: 600; color: var(--text, #1a1a1a); margin-bottom: 20px; padding-bottom: 16px; border-bottom: 1px solid var(--border, #eee); }
  .body { white-space: pre-wrap; font-size: 14px; line-height: 1.7; color: var(--text, #1a1a1a); }
</style>

<div class="tabs">
  <button class="tab-btn active" onclick="show(0)">TAB LABEL 1</button>
  <button class="tab-btn" onclick="show(1)">TAB LABEL 2</button>
  <button class="tab-btn" onclick="show(2)">TAB LABEL 3</button>
</div>

<div id="p0" class="tab-panel active">
  <div class="subject-line">Subject line</div>
  <div class="subject-value">SUBJECT LINE 1</div>
  <div class="body">EMAIL BODY 1</div>
</div>
<div id="p1" class="tab-panel">
  <div class="subject-line">Subject line</div>
  <div class="subject-value">SUBJECT LINE 2</div>
  <div class="body">EMAIL BODY 2</div>
</div>
<div id="p2" class="tab-panel">
  <div class="subject-line">Subject line</div>
  <div class="subject-value">SUBJECT LINE 3</div>
  <div class="body">EMAIL BODY 3</div>
</div>

<script>
  function show(i) {
    document.querySelectorAll('.tab-panel').forEach((p, j) => p.classList.toggle('active', i === j));
    document.querySelectorAll('.tab-btn').forEach((b, j) => b.classList.toggle('active', i === j));
  }
</script>
```

## Step 5: Add a brief strategy note

After the widget, include a short italicized note (3–6 sentences) covering all three variations — explain what makes each angle distinct and when the user might prefer one over another. This helps the sender make an informed choice, not just pick at random.

Example:
*Strategy note: The "Credibility First" version leads with a concrete result to earn trust before making the ask — best if they've heard of you or your company. "Warm & Curious" uses a question hook to lower defenses — works well when the relationship is cold but the recipient is likely time-poor. "Short & Sharp" is the highest-risk, highest-reward option — use it if you know they're a no-fluff person or if your previous emails have gone unread.*

## When the user has a draft

If they already have a draft and want it improved:
1. Identify the email type
2. Read the reference file
3. Diagnose what's not working and why (be specific, be honest)
4. Offer a rewrite OR specific edits — ask which they prefer if unclear
5. Explain the changes in the strategy note

## Final sanity checks before delivering

- Is this email even the right medium? (Some things belong in a call or in person — say so if relevant)
- Is the timing right? (A follow-up sent 2 hours after the first email often backfires)
- Is the CTA clear and singular? (Multiple asks dilute each other)
- Would you send this if your name were on it?

## no_claude_vices mode

If the user includes `no_claude_vices` anywhere in their request, or has indicated this as a preference, apply the following rules to all output — the email itself, the subject line, and the strategy note.

The goal is writing that reads like a sharp human wrote it. The rules below target the specific patterns that make AI-generated text detectable.

**Typography**
- Never use the em dash (—). Use a hyphen (-), a comma, or restructure the sentence.
- Never use semicolons (;). Split into two sentences, use a comma, or restructure.
- Avoid ellipses (...) for dramatic effect. Use them only for genuine omission.

**Word substitutions** — replace these automatically:
- "utilize" → "use"
- "leverage" (as a verb) → "use", "apply", "draw on"
- "ensure" → "make sure", or restructure
- "facilitate" → "help", "enable"
- "streamline" → "simplify", "cut"
- "comprehensive" → "full", "complete", "thorough" — or cut it
- "robust" → "strong", "solid", "reliable"
- "delve" → "look into", "dig into"
- "actionable" → "concrete", "specific", or cut
- "seamless" → "smooth", "easy", or cut
- "in order to" → "to"
- "due to the fact that" → "because"

**Phrase substitutions** — say the thing directly:
- "It's worth noting that..." → cut the preamble, say the thing
- "It's important to note that..." → same
- "It's crucial to understand..." → same
- "At the end of the day" → cut or rephrase
- "Moving forward" → cut or rephrase
- "In today's [X] landscape" → cut entirely
- "First and foremost" → "First"
- "Each and every" → "every" or "each"
- "The fact of the matter is" → cut

**Structure**
- Don't open with "Certainly!", "Absolutely!", "Of course!", "Sure!", "Great question!" — get straight to the content
- Don't close with "I hope this helps!", "Feel free to reach out!", "Let me know if you need anything!" — end on the substance
- Don't restate the user's request before responding
- Use bold sparingly — only when a skimming reader genuinely needs to land on that word
- Prefer prose over bullet points when content flows naturally as sentences
- Don't number things that aren't genuinely sequential

**Voice**
- Prefer active voice ("We decided X", not "It was decided that X")
- Avoid false-balance hedging ("While X is true, it's also important to consider Y...") when you simply want to say Y
- Skip parenthetical over-explanations (i.e., phrases that explain things that don't need explaining)
- Vary sentence structure — don't start multiple consecutive sentences with the same word or construction
