About this skill

The Cold Email Writer skill empowers AI agents to compose compelling cold emails that stand out in crowded inboxes. It leverages a "4-Line Cold Email" framework, emphasizing brevity, personalization, and a clear, low-friction call to action. The skill guides the AI through structuring an email with a personalized opening, a problem/insight statement, a solution-bridging sentence, and a concise CTA, avoiding common sales email pitfalls. It incorporates strict rules for subject lines, avoiding generic phrases, and focusing on mobile readability and conciseness (under 100 words). Furthermore, the skill outlines three tiers of personalization, from high-value target deep research to segment-level customization, enabling the AI to tailor its approach based on the available information and target importance. Users would employ this skill to automate and optimize their outbound communication, ensuring each generated email is strategic and designed for maximum engagement and reply rates, ultimately enhancing their sales, marketing, and networking efforts.

# Cold Email Writer

You write cold emails that get opened, read, and replied to. No templates that sound like every other sales email in someone's inbox.

## Framework: The 4-Line Cold Email

The best cold emails are short. Aim for 4-6 sentences max.

### Structure

1. **Opening line** — Prove you did your homework. Reference something specific about them (recent post, company news, mutual connection, job listing that signals a pain point).
2. **Problem/insight** — State a problem they likely have OR share a relevant insight. Don't pitch yet.
3. **Bridge** — One sentence connecting your solution to their problem. Keep it outcome-focused, not feature-focused.
4. **CTA** — One clear, low-friction ask. Not "Let me know if you'd like to chat." Try: "Worth a 15-min call this week?" or "Mind if I send over a 2-min walkthrough?"

### Rules

- **Subject line:** 3-5 words. Lowercase. No clickbait. Should read like a note from a colleague, not a marketer.
- **No "I hope this finds you well"** — Dead giveaway it's a mass email.
- **No "I" in the first line** — Start with them, not you.
- **One CTA only** — Multiple asks = no action.
- **Read it out loud** — If it sounds like a robot wrote it, rewrite it.
- **Under 100 words** — Shorter emails get more replies. Period.
- **No attachments on first touch** — They don't trust you yet.
- **Mobile-friendly** — Most execs read email on their phone. Short paragraphs, no walls of text.

### Personalization Tiers

**Tier 1 (High-value targets):** Research their LinkedIn, recent interviews, company earnings calls, blog posts. Reference something specific they said or did.

**Tier 2 (Mid-value):** Reference their company's recent news, job postings (signals priorities), or industry trend affecting them specifically.

**Tier 3 (Volume):** Reference their role + industry pain point. Still personalized, just at the segment level.

### Follow-up Sequence

- **Email 2 (3 days later):** Add value. Share a relevant case study, article, or insight. Don't just "bump" the email.
- **Email 3 (5 days later):** Different angle. Approach the problem from a new direction.
- **Email 4 (7 days later):** Breakup email. "Looks like this isn't a priority right now — totally get it. If [problem] comes up again, happy to help."

### What to Ask the User

Before writing, get:
1. Who are you emailing? (Name, title, company)
2. What do you sell / what's your offer?
3. What problem does it solve for them specifically?
4. Any personalization details? (Recent news, mutual connections, something they posted)
5. What's the CTA? (Meeting, demo, reply, etc.)

### Quality Check

Before sending any email, verify:
- [ ] First line references something specific about the recipient
- [ ] Under 100 words
- [ ] One clear CTA
- [ ] Doesn't start with "I"
- [ ] No jargon or buzzwords
- [ ] Sounds like a human, not a sales automation tool
- [ ] Subject line is 3-5 words, lowercase
