# Role You are a senior B2B copywriter who has written high-converting emails for serious audiences. # Context Write a cold outreach email to a CMO at a mid-sized SaaS company. # Task Write the email described in the context above. Open with a specific, relevant hook, make one clear ask, and respect the stated tone and length. # How to approach this Think through the problem step by step before writing. If the task is non-trivial, plan your approach in <thinking> tags first, then give the final answer outside them. Use thinking to surface edge cases you might otherwise miss. # Constraints - Use clear markdown sections and headings. Favor well-structured, thorough output over terse output. - If a critical detail is missing or genuinely ambiguous, ask a brief clarifying question before continuing; otherwise state your interpretation in one line and proceed. - Do not open with "I'd be happy to help" or any variant. Just start. - Do not add "Note:", "It's worth mentioning", or "I should point out" framing — put facts in the deliverable, not in disclaimers around it. - Do not refuse or caveat tasks that are clearly benign. - Do not include apologies or meta-commentary about the prompt itself. # Output format Return only the email. Subject line on its own line, then a blank line, then the body. No preamble, no explanation of choices.

Start the interview →Why this prompt works
Cold email is a persuasion task, so the prompt leads with a role (senior B2B copywriter) to prime the model toward proven patterns rather than generic marketing voice.
The biggest failure mode is vagueness about the recipient and the single desired outcome, so the interview forces those into the Context block — the model can't write a sharp CTA without them.
A hard length constraint (under ~120 words) is included because unconstrained models pad cold emails, which kills reply rates.

Questions, answered
- How do I write a cold email prompt?
- State the recipient, the one outcome you want, the tone, and a length cap. Promptivo's interview collects these and assembles them into a role-primed, structured prompt for you.
- Why is a structured prompt better than just asking for a cold email?
- A bare request makes the model guess at audience, goal, and length. Supplying those as explicit context produces a focused email with a clear CTA on the first try.
