What a campaign brief includes
A campaign brief aligns everyone touching a campaign (you, the team, any freelancer) on one page: the goal as a business outcome, 2-3 measurable objectives beneath it, the audience and what they should do differently, one key message every channel carries, the channels-and-assets table (what runs where, which asset it needs, who makes it), the budget with media split from production, the timeline back-planned from the immovable date, and the KPIs with the wrap-up review booked before launch.
That last habit is the cheapest one on the page: campaigns that are never scored teach nothing, and next season’s brief starts from guesswork again.
How to write a campaign brief, field by field
Goal: a business outcome with a number, not a marketing activity: “40 bookings for the autumn workshops”, never “raise awareness of the workshops”.
Objectives: the 2-3 measurable steps that add up to the goal (visits, enquiries, conversion), so mid-campaign you can see which stage is underperforming rather than just feeling behind.
Message: one sentence every channel carries; if channels need different messages, you may have two campaigns.
Channels and assets: weight the table by what your own past campaigns actually delivered, and give each asset an owner and a date.
Timeline: back-plan from the date that cannot move.
KPIs and wrap-up: 3-5 numbers that define success, and the review in the calendar from day one, so the campaign ends with lessons on record instead of a shrug.
Campaign brief vs creative brief: what is the difference
The two are routinely conflated, and the confusion produces documents that do neither job. The campaign brief (this page) covers the whole initiative: one goal, one audience, one message, several channels and several assets, with budget and timeline for all of it.
The creative brief covers one asset within it: this landing page, this video, this flyer, briefed deeply enough that a designer or freelancer can make it without a follow-up call. They nest: the campaign brief’s asset table typically spawns one creative brief per designed asset. If your “brief” is trying to specify Instagram copy and the overall budget in the same document, split it.

# Campaign Brief Generator
_By readywhen. Full guide + free template: https://readywhen.ai/campaign-brief-template_
You are writing a campaign brief: the one-page document that aligns everyone on a whole initiative across channels.
## Principles
- The goal is a business outcome ("40 bookings for the autumn workshops"), and every objective beneath it is measurable.
- One key message carried by every channel; channel-specific angles support it, never replace it.
- The channels-and-assets table is the working heart: what runs where, which asset it needs, who makes it. Any asset needing a designer gets its own creative brief; this document does not brief individual assets.
- Budget splits media from production. Conflating them is how campaigns end up with ads and nothing to run in them.
- Book the wrap-up review at the start. Campaigns that are never scored teach nothing.
- Use only the numbers, dates and audience facts provided; mark gaps rather than inventing them.
## What I need from you
What you’re promoting and the business outcome you want · who it’s for · budget and dates · channels you can actually run · what’s worked before. Ask me for anything missing before you write.

_Made by readywhen. readywhen drafts the brief from your own campaign context: the offer in your docs, the audience you’ve defined, the dates on your calendar. https://readywhen.ai/campaign-brief-template_
Let readywhen do itRecommended
The campaign’s facts already exist in your docs, plan and calendar. readywhen assembles them into a brief the team can run with, weighted by what your last campaign actually taught you.
The offer, audience and dates are already in your tools. readywhen drafts the brief in ~45 seconds, instead of the week of chasing details everyone already wrote down.
Let readywhen draft your campaign brief from your own context
By the time a campaign needs a brief, most of its facts exist: the offer sitting in a doc, the audience you defined in the marketing plan, the immovable date on the calendar, and, most valuably, the wrap-up notes from last time.
readywhen assembles those into the brief: objectives sized from your real baselines, the channel table weighted by what actually delivered before, the timeline back-planned from the fixed date, and the assets flagged that need their own creative briefs. The team gets a brief they can run with; the campaign inherits its own history.

Campaign brief FAQs
What is the difference between a campaign brief and a creative brief?
Scale and nesting. The campaign brief covers the whole initiative: one goal, several channels and assets, budget and timeline for all of it. A creative brief covers one asset within the campaign, briefed deeply enough for a designer to make it. The campaign brief’s asset table typically spawns one creative brief per designed asset.
What is the difference between a campaign brief and a marketing plan?
Horizon. The marketing plan sets the year: audience, positioning, standing channels, budget. A campaign brief covers one bounded initiative inside it, with its own goal, dates and wrap-up. Campaigns should visibly inherit from the plan, not freelance against it.
How long should a campaign brief be?
One to two pages. It is an alignment document: long enough that nobody needs a follow-up meeting to understand the campaign, short enough that everyone actually reads it before kickoff.
What makes a good campaign objective?
A measurable stage on the way to the goal: landing-page visits, enquiries, bookings at a target value. Two or three of them let you diagnose mid-campaign (traffic fine, conversion weak) instead of just sensing that things are behind.
Is there a campaign brief template for Google Docs or Word?
Yes. Copy the plain-text template on this page into Google Docs, Word or Notion, or download it as a file. All formats are free.
Can’t I just use ChatGPT or Claude to write my campaign brief?
Yes. Paste the offer, dates and budget with the prompt above, and you get a complete brief. readywhen is the version that already holds the campaign’s facts, including the wrap-up notes from last time, so the new brief inherits your own lessons instead of restarting from theory.
