TL;DR — A campaign brief is the contract between strategy and execution. The nine-section template below is the one we use inside STRAETCH and have refined with lean B2B teams across SaaS, fintech and consumer electronics. It is also AI-ready: each section corresponds to a field a contextual AI system needs to draft assets in your voice.
Why most campaign briefs underperform
In our work with 200+ lean B2B teams, weak briefs share three patterns:
- Activity, not outcome. "Run a webinar" is not a campaign goal.
- Three audiences. Trying to talk to CMOs, RevOps and SDRs in the same campaign produces messaging nobody acts on.
- No definition of done. The campaign quietly trails off; nobody runs a review.
The template below is structured to make each of those mistakes hard.
The nine sections of a working brief
Each section maps to a step below. Treat them as required, not optional — the discipline is the value.
How to use the template
- 1
Name the campaign and tie it to a strategic objective
Write one sentence that links the campaign to the company OKR or strategic theme it serves. If you can't, the campaign is not ready to brief.
- 2
Define the primary audience and the job-to-be-done
Pick one primary ICP and one job-to-be-done. Resist the urge to list three. Specificity is what makes the AI draft useful.
- 3
Write the single message
One sentence the audience should be able to repeat after the campaign. Everything else supports it.
- 4
Set the success metric and target
One leading metric (e.g. qualified pipeline) with a number and a date. Add at most one supporting metric.
- 5
Choose channels and formats
Map the message to channels where the audience actually pays attention. Two channels run well beats five run badly.
- 6
List the assets and owners
Every asset gets one owner and one due date. Reviewers are named, not implied.
- 7
Capture the brand voice and no-go rules
Even a one-line brand voice note (e.g. 'plainspoken, no hype') anchors AI drafts.
- 8
Define 'done'
What does shipped mean — live, attributed, measured? Write it down so nobody renegotiates at the end.
- 9
Schedule the review
Book the post-campaign review now, with the right metrics shown. Otherwise the loop doesn't close.
Worked example
Campaign name — Q3 2026: From audit to action
Strategic objective — Convert dormant trial users into paying teams.
Primary audience — Heads of Marketing at 10–50-person B2B SaaS companies who completed onboarding but did not invite a teammate within 30 days.
Job-to-be-done — "Show me that this tool will save my team's time this quarter, not next year."
Single message — Your strategy is already in STRAETCH. Inviting your team turns it into pipeline.
Success metric — 60 trial-to-paid conversions by 30 September.
Channels — Lifecycle email (3-touch sequence) + one LinkedIn ad set retargeting trial visitors.
Assets — Email 1 (D. Hardarson, 5 Aug), Email 2 (D. Hardarson, 12 Aug), Email 3 (D. Hardarson, 19 Aug), LinkedIn creative (Design, 1 Aug), Landing page refresh (Design, 1 Aug).
Brand voice — Plainspoken, founder-led, no hype. No emojis. No "supercharge".
Done — All assets live, attribution wired to /signup, post-campaign review booked for 7 October with conversion-to-paid as the headline metric.
Frequently asked questions
What should a campaign brief include?
Nine sections: campaign name and strategic objective, primary audience and job-to-be-done, single message, success metric and target, channels and formats, assets and owners, brand voice and no-go rules, definition of done, and a scheduled post-campaign review.
How long should a campaign brief be?
One page is the target. If the brief runs longer than a page, it usually contains either two campaigns or unresolved disagreements that need a conversation, not more bullet points.
Can AI write a campaign brief?
Yes — with a caveat. Contextual AI tools that know your strategy, brand and audience can draft a credible first version of every section. The marketer's job becomes editing for nuance and locking the definition of done, not authoring from a blank page.
Do small teams really need a formal brief?
Yes. The cost of a one-page brief is 30 minutes. The cost of a no-brief campaign is a half-quarter of misaligned execution. The smaller the team, the higher the cost of misalignment per person.
