Campaign Brief prompts for Marketing Manager

Ready-to-use AI prompts for campaign brief — written for Marketing Manager and easy to paste into ChatGPT, Claude or Gemini.

Draft a full campaign brief

You are a senior marketing strategist. Write a campaign brief for [product or service] targeting [audience] with a budget of [budget] over [timeframe]. What you know: our positioning is [positioning], our main competitor is [competitor], the business goal is [goal and metric], and the constraint is [constraint]. Structure the brief as: Objective (one measurable sentence) · Audience insight (what they actually believe today and what we need them to believe) · Single-minded proposition · Reasons to believe (max three) · Channel plan with rough budget split and rationale · Key messages per channel · Success metrics with target numbers · Risks and what we will not do. Keep it to one page. Flag any place where you had to assume something I did not tell you.

Pressure-test a campaign idea

Act as a skeptical CMO reviewing a campaign proposal. Here it is: <brief> [campaign idea] </brief> Budget: [budget]. Goal: [goal]. Audience: [audience]. Challenge it honestly: Is the audience insight real or a stereotype? Does the creative idea depend on the audience caring more than they do? Is the budget split defensible? What is the single assumption that, if wrong, sinks the whole thing? Give me: three hard questions I should be able to answer before spending money, the weakest part of the plan with a specific fix, and one cheaper test that would validate the core assumption in under two weeks. Be blunt — I would rather hear it now than after launch.

Turn a brief into a launch calendar

You are a marketing operations lead. Convert this campaign brief into an execution calendar. <brief> [brief] </brief> Launch date: [launch date]. Team: [team]. Channels: [channels]. Output a table with columns: Week, Deliverable, Owner role, Dependency, Status gate. Work backward from launch so that dependencies (creative approval, legal, asset production, media booking deadlines) land before the things that need them. Add a pre-launch checklist and a post-launch measurement schedule for days 1, 7, and 30. Call out any deliverable that is unrealistic for the stated team size, and propose what to cut rather than silently overloading the plan.
