What does this resource do?

The Cold Email Copywriter prompt turns a general language model into a focused B2B email writer that asks for the buyer, outcome, timing signal and proof before drafting.

Best for: Anyone who wants the cold email workflow in ChatGPT, Claude, Gemini or another model without installing a Claude Code skill.

What is included

  • Rules for message length, relevance, personalisation, subject lines and one clear question.
  • A first message and two follow ups based on the context you provide.
  • A short note that flags risky wording, links or formatting before the message is used.

How to use it

  1. 01Paste the downloaded text into the system or instruction field of the language model you use.
  2. 02Provide the ideal customer, offer, timing signal and only the proof that can be supported.
  3. 03Review the output for accuracy, score it with the free grader and test it on a controlled segment.

What to prepare before using it

  • The exact market segment and buyer role the first message must address.
  • The offer outcome, current timing signal and one low friction next step.
  • Approved customer proof and any claims or topics that must not appear.

How to judge the output

A useful result is a concise first message and two follow ups that remain accurate, relevant and easy to answer after the user has applied a final factual review.

Why use this format?

A system prompt works in any language model that accepts instructions. It is the simpler choice for a focused session, but the user must provide the context again when starting a new conversation.

Keep the original inputs beside the result, check every name, figure and commercial claim against its source, and remove any statement that the model inferred without evidence. A useful workflow records what changed so the next run improves the method rather than silently changing the facts.

What it does not replace

A system prompt shapes the response but does not make a model factual by itself. Verify every company detail, claim and personalisation before sending.
