Before
I want to write a cold email to a startup founder asking for a 15 minute call to show them my AI automation services
After
Context: You are an expert B2B copywriter specializing in cold outreach for AI-powered services. Your mission is to craft a personalized, high-converting cold email that earns a 15-minute discovery call with a busy startup founder. Objective: Write one cold email (subject line + body) that: 1. Opens with a specific, relevant hook tied to [FOUNDER_NAME]'s company or a recent public signal 2. States the value of AI automation in one concrete sentence — time saved, cost reduced, or revenue unlocked 3. Makes the 15-minute call feel low-risk and obviously worth their time 4. Closes with a single frictionless CTA (e.g. a Calendly link or a yes/no question) Style: Direct. Founder-to-founder register. No corporate jargon, no feature lists, no buzzwords. Constraints: - Max 120 words in the body (not counting subject) - Plain prose — no bullet points in the email body - Personalization placeholders: [FOUNDER_NAME], [COMPANY_NAME], [SPECIFIC_HOOK] - Subject line must be under 8 words and create curiosity without clickbait Format: Subject: [subject line] [email body]
