Writes personalized cold emails that actually get replies
README (SKILL.md)

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

Usage Guidance
This skill is a straightforward guide for composing cold outreach; it does not access your system or request credentials. Before using output in real outreach, review each message for accuracy, privacy, and compliance: remove any accidental inclusion of sensitive data, confirm you have the right to contact recipients, and ensure messages comply with anti-spam laws and company policy. If you want the agent to actually send emails, that will require separate mail-sending integrations (SMTP/Gmail/CRM) and associated credentials — expect those to be requested at that time and review them for proportionality. Finally, avoid using the skill to automate harassment or illegal activity; keep personalization ethical and consent-respecting.
Capability Analysis
Type: OpenClaw Skill Name: afrexai-email-crafter Version: 1.1.0 The skill bundle includes external links in `SKILL.md` and `README.md` to `afrexai-cto.github.io`. The `SKILL.md` explicitly instructs the agent to 'Browse Context Packs' at one of these URLs. If the agent has web browsing capabilities, this constitutes an external network call to an untrusted domain. While presented as marketing for related products, this introduces a potential vector for tracking or fetching dynamic content, which is a risky capability not strictly necessary for the core email writing function.
Capability Assessment
Purpose & Capability
The name and description match the SKILL.md. There are no declared env vars, binaries, or install steps that would be unnecessary for a text-generation/instruction skill; everything asked for (recipient, offer, problems, personalization) is relevant to producing personalized cold emails.
Instruction Scope
SKILL.md contains only guidance for composing emails, personalization tiers, and a checklist. It does not instruct the agent to read system files, access environment variables, invoke external APIs, or transmit data to unexpected endpoints. It does include marketing links to AfrexAI pages but those are external references, not runtime exfiltration instructions.
Install Mechanism
No install spec and no code files — instruction-only content. This is the lowest-risk install profile (nothing is written to disk or executed).
Credentials
No required environment variables, credentials, or config paths are declared or referenced; the skill does not request secrets or unrelated credentials.
Persistence & Privilege
Flags show default behavior (always:false, agent-invocable allowed). The skill does not request permanent presence or to modify other skills or system settings.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install afrexai-email-crafter
  3. After installation, invoke the skill by name or use /afrexai-email-crafter
  4. Provide required inputs per the skill's parameter spec and get structured output
