Campaign Brief

What it is

A campaign brief is your single source of truth for campaign planning and execution. It documents the strategic thinking, creative direction, tactical approach, and success criteria that everyone – internal teams, agencies, stakeholders – works from. A good brief prevents scope creep, aligns expectations, and gives teams the clarity they need to do their best work.

Think of it as the contract between strategy and execution: everything you commit to achieving and how you’ll achieve it.

When to use it

Use a campaign brief when you’re planning:

• Multi-channel marketing or communications campaigns with defined start and end dates
• Product or service launches requiring coordinated activity
• Awareness or behaviour change campaigns with specific objectives
• Agency-led creative development or media buying
• Internal campaigns (recruitment, culture change, policy adoption)

Don’t use a campaign brief for:

• Always-on communications activity (use Editorial Calendar instead)
• Single-tactic executions (a press release doesn’t need a full brief)
• Crisis response where speed trumps documentation
• Early-stage exploration before strategy is clear

Inputs needed

Before you start, gather:

• Business context: What’s happening in the organisation/market that makes this campaign necessary?
• Campaign objective: What specific outcome are you trying to achieve?
• Audience research: Who are you targeting? What do you know about their behaviours, motivations, barriers?
• Budget: What’s available to spend? Any constraints?
• Timeline: When must this happen? What are the immovable dates?
• Assets: What do you already have? What needs creating?
• Stakeholders: Who needs to approve what?

AI prompt

Base prompt

I need to create a campaign brief for [CAMPAIGN NAME/TYPE].

Context:
- Campaign objective: [SPECIFIC MEASURABLE OUTCOME]
- Target audience: [WHO - with demographic and psychographic detail]
- Campaign period: [START DATE to END DATE]
- Budget: [AMOUNT]
- Background: [WHY THIS CAMPAIGN IS NEEDED]
- Key dates/milestones: [ANY IMMOVABLE DEADLINES]

Please create a comprehensive campaign brief that includes:
1. Campaign Overview (name, period, background, objective)
2. Target Audience (demographics, psychographics, desired action, motivation)
3. Strategic Approach (single-minded proposition, 3 key messages, tone, creative direction, mandatories)
4. Channel Strategy (channel mix table with role, tactics, budget)
5. Timeline & Milestones (pre-campaign, live, post-campaign activities)
6. Budget & Resources (breakdown and team requirements)
7. Measurement (success description, 3 primary KPIs with targets, reporting approach)
8. Governance (approval workflow, sign-off authority)
9. Risks & Contingencies (3-4 key risks with mitigation)

Make the brief detailed enough to brief an agency or align a cross-functional team, but concise enough to remain usable.

Prompt variations

For agency briefing:

Add: “This brief will be used to brief creative and media agencies. Include clear creative parameters, any brand guidelines they must follow, and specific deliverables required.”

For B2B campaigns:

Add: “This is a B2B campaign targeting [ROLE/INDUSTRY]. Focus on business outcomes, longer sales cycles, and account-based approaches rather than mass reach.”

For behaviour change campaigns:

Add: “This campaign aims to change behaviour around [TOPIC]. Include barrier analysis, behaviour change model being used (e.g., COM-B, stages of change), and how we’ll measure behaviour shift not just awareness.”

For product launches:

Add: “This is a product launch campaign for [PRODUCT]. Include market context, competitive positioning, launch phases (tease, reveal, availability), and clear sales/conversion goals.”

For internal campaigns:

Add: “This is an internal employee campaign. Focus on employee engagement channels, manager enablement, two-way communication mechanisms, and cultural/behavioural outcomes.”

Human review checklist

Before using your campaign brief, verify:

• Objective is genuinely measurable – Can you track whether you achieved this or not?
• Audience insight is real, not assumed – Have you based this on research, data, or actual audience conversation?
• Single-minded proposition is actually single-minded – Could you say it in one breath?
• Channel mix is justified, not just listed – Have you explained why this combination?
• Timeline is realistic – Have you accounted for approval time, production lag, holidays, other campaigns?
• Budget adds up correctly – Do all line items plus contingency equal total budget?
• KPIs are achievable – Based on benchmarks or past performance, are these targets realistic?
• Risks are genuine – Are these actual threats or just “might be a bit challenging”?
• Approval workflow is clear – Does everyone know what they’re approving and when?
• Stakeholders have bought in – Have key decision-makers reviewed and approved this direction?

Tips for success

Involve stakeholders early: Don’t brief the campaign and then ask for approval. Get input during brief development to build buy-in.

Be specific about constraints: “Limited budget” is vague. “£140k total, with 55% minimum allocated to media” is clear.

Make the creative direction actionable: “Be innovative” doesn’t help a creative team. “Show future/present self interaction, avoid stock photography, use real customer scenarios” does.

Budget for contingency: 7-10% contingency isn’t pessimism – it’s acknowledging that production costs vary and opportunities emerge.

Plan the evaluation upfront: If you decide how you’ll measure success after the campaign launches, you’ve already lost the opportunity to gather baseline data.

Common pitfalls

Confusing campaign objective with business objective: “Increase revenue by 15%” is a business objective. “Acquire 15,000 new customers” is a campaign objective. The campaign contributes to business goals but isn’t solely responsible for them.

Generic audience descriptions: “Women 25-45” isn’t an audience insight. It’s a demographic bracket that includes hundreds of different people with different needs.

Too many messages: If you have six key messages, you don’t have any. Three maximum, ideally one single-minded proposition supported by proof points.

Timeline ignoring approval reality: If legal review typically takes two weeks and you’ve given them three days, your timeline is fiction.

Briefs written for the file, not for use: If your campaign team never refers to the brief during execution, it was a compliance exercise not a strategic document.
