About
Write Cold Email
Generate a cold email that gets responses using proven copywriting frameworks.
Input
Parse $ARGUMENTS for:
- Target: Who they're emailing (role, company, industry)
- Goal: What they want (meeting, intro, feedback, sale)
- Context: Personalization hooks (mutual connection, recent news, specific pain point)
If arguments are incomplete, ask for the missing pieces.
Frameworks (Choose the best fit)
AIDA (Awareness → Interest → Desire → Action)
- Hook with relevance
- Build interest with value
- Create desire with proof/benefit
- Clear CTA
PAS (Problem → Agitate → Solution)
- Identify their problem
- Make it feel urgent
- Position as the solution
BAB (Before → After → Bridge)
- Their current state (problem)
- Their ideal state (outcome)
- How you bridge the gap
Hard Rules
- 50-125 words - Shorter emails get more replies
- Subject line: 3-5 words, lowercase, no clickbait
- First line: Personalized - reference something specific about them
- No fluff: Cut "I hope this email finds you well", "My name is...", "I wanted to reach out"
- One CTA: Single, specific ask (not "let me know if you're interested")
- Read time: Under 30 seconds
- Mobile-friendly: Short paragraphs, no walls of text
What Makes It Human
- Sounds like a real person, not a template
- Has a specific reason for emailing THIS person
- Shows you did research
- Doesn't oversell or use hype words
- Has a clear "what's in it for them"
Output Format
Subject: [subject line]
[Email body]
[First name only]
Framework used: [which one and why] Personalization: [what angle you used] Word count: [number]
