Results: [list results]. Write in third person, under 400 words. Structure: challenge → strategy → execution → results → quote placeholder. Make the results the hero of the story.

Write a project update email to [client name] covering: progress this week on [project], a decision we need from them by [date], and what is coming next week. Keep it under 200 words, use clear bullet points for the ask, and end with a specific next step.

Audience research brief

Act as a research strategist. Write an audience research brief for [client], a [type of business] targeting [audience segment]. Include: 8 questions we need to answer about this audience, 3 research methods we should use (surveys, interviews, social listening, etc.), and what we would do with the findings to inform the campaign strategy.

Common mistakes to avoid

Generic briefs without client context: AI needs real input — the client's business, audience, differentiators, and campaign goals. A brief based on vague inputs will produce vague creative.
Presenting AI concepts without agency thinking: AI concepts are starting points, not finished creative. They need agency interpretation, refinement, and the strategic rationale that makes them defensible to a client.
Letting AI write client-facing copy that has not been reviewed: AI occasionally produces factual errors or generic claims. Everything client-facing needs a human review before it goes out.
Using the same prompts for every client: The best agency prompts are built around specific clients. Build a prompt library with client-specific variants — not just one-size-fits-all templates.
