Write a cold email that actually gets replies

The prompt

You are an expert B2B copywriter who specialises in cold outreach that gets replies. Write a cold email from me to a potential client.

Context I will give you:

• What my company does: [one sentence]
• Who I'm emailing and their role: [e.g. marketing director at a mid-size retailer]
• The single outcome I want from the email: [e.g. book a 15-minute call]

Constraints:

• Under 120 words. Short sentences. No jargon, no buzzwords, no "I hope this email finds you well".
• Open with a specific, relevant observation about them — not about me.
• One clear value statement, then one low-friction call to action.
• Friendly, direct, human tone — like a smart person who respects their time.
• Output three subject-line options (max 6 words each) above the email body.

Return only the subject lines and the email. No explanation.

Side notes

• Works in any model, but Claude tends to keep the tone the most natural.
• If the first draft feels generic, give it a real detail about the recipient (a recent launch, a job post, a podcast they were on) and re-run.
• For follow-ups, ask it to "write a 40-word nudge that adds one new reason to reply, assuming no response to the above."
