You just spent hours writing the perfect marketing brief. It’s cleanly formatted, with clear deliverables, timelines, and brand guidelines. You’ve shared it with your agency partners and internal teams. Job done, right?

Not quite.

Your inbox pings—an agency project manager has a list of fifteen follow-up questions. Legal DMs you: they want to review all assets before launch. And suddenly, you’re scrambling to find your workback timeline while wondering how everything got so confusing.

Sound familiar? A poorly written creative brief can unravel even the best campaign plans. At Sherlock, we’ve helped brands manage briefs for everything from localized retail rollouts to 50,000-asset global product launches. And we’ve seen one truth over and over: the better the brief, the smoother the execution.

Whether you’re new to writing briefs or you’re looking for a more efficient way to align global teams, this guide covers how to write a marketing or creative brief that actually works—and includes free brief templates to get you started.

What Does a Strong Marketing Brief Look Like?

A strong marketing brief serves as a source-of-truth document that aligns every stakeholder—creative teams, agencies, reviewers, legal, and marketing leads. Depending on your project scope, a brief may be detailed and production-focused, or high-level and strategic.

If you’re wondering what a brief should include, here’s a quick checklist:

Project background and objectives
Target audience
Key messaging and tone of voice
Deliverables and specs (with platform or regional requirements)
Brand guidelines and visual references
Timeline and milestones
Stakeholders, reviewers, and approvers
Distribution or asset handoff plan

We’ve included examples of these in our downloadable creative brief templates—grab them now to save time on your next project.

If you’re briefing large-scale projects, read on…

Running a multi-channel or global marketing campaign isn’t as simple as sending over a few bullet points to your creative partners. When you’re dealing with numerous deliverables across multiple teams, agencies, or freelancers (sometimes all at once!), the way you brief can make or break a campaign. In these scenarios, your brief needs to be a comprehensive, source-of-truth document that keeps every stakeholder aligned—from creative exploration through final delivery.

However, not all briefs require the same level of detail. For a large-scale campaign, you’ll generally need more granularity and clearly documented specs. But if you’re looking for top-line creative direction—like a photoshoot or conceptual campaign ideation—you might opt for a more strategic, high-level brief that sparks creativity without getting bogged down in technical minutiae. In this post, we’ll focus on how to brief effectively for bigger marketing projects and share tips and templates you can use to streamline your process.

Why Briefs Matter—Especially for Big Campaigns

At Sherlock, we create and manage briefs that get shared with designers, vendors, and client teams around the world. We’ve seen firsthand that the more complex and far-reaching a campaign is, the more critical it is to have a bulletproof briefing process.

Think of creative production like a complex recipe and you’ll understand the importance and frustration of investing in the planning process. That new viral recipe everyone is making looks amazing—you’re so excited for the finished product that you dive right in, deciding to add and prep ingredients as you go. But somewhere around step six, you realize that you should have been marinating the chicken overnight. And – wait, what’s black garlic? Oops, you threw out the pasta water. Is that bad? As you get closer to dinner, your vision of a beautiful, showstopper main course turns into a sad, flavorless goo. A thorough, comprehensive brief anticipates these elements up front, giving you the best chance of delivering a campaign on time, on brand, and on budget.

The anatomy of a creative production project

Big or small, most creative production projects look pretty similar when you get down to their skeletal structure. It might seem simple, but it’s easy to get lost in the details, so remembering the high-level structure of your creative production projects can be helpful. This post will cover that first step of planning and pre-production – specifically, why a good brief makes all the difference. In the rest of the series, we’ll detail the other steps in the framework and share best practices for maximizing efficiency and minimizing chaos.

The lovely thing about using templates and understanding the core pillars of your projects is that once you’ve got the process of briefing down, it becomes a lot easier to throw one together. Once you and all your contacts are on board with how projects run, everyone can take what they have and run with it. But if your briefing style keeps changing, or you run into issues without then reflecting changes in later briefs, things just won’t improve.

First and foremost: know your stakeholders

Identifying everyone involved is the first big step—especially when multiple agencies, teams, and freelancers are working in parallel. Who will actually do the work? Which stakeholders need to review and approve? Who’s responsible for final sign-off? Start by making a list of everyone involved.

Execution Team
- Are they in-house or external?
- Will different agencies handle different parts of the campaign (e.g., Agency A for creative exploration, Agency B for translation and localization)?
Reviewers
- Do you need regional marketing teams to review assets for local compliance?
- Does Legal need to check everything before it goes out?
- Is there a separate brand or creative director who signs off on the “look and feel”?
Receivers of Final Assets
- Who needs the final deliverables, and in what format?
- Are there specific naming conventions or file types required by external vendors or retailers?

By clarifying these questions in your brief, you avoid the dreaded “Wait, what am I supposed to do with this?” response from reviewers. Large-scale campaigns often involve more layers of approval—so it’s vital to set expectations early and communicate them clearly.

Okay, now you have your brief audience listed out, think about who these people are and what information they need to know. For example, if you’re sharing this work out to an agency, how new are they? Have they worked on this type of project before? It can be easy to forget that while your company’s brand guidelines are ingrained into your very soul, a newish agency designer might not be aware that your logo can never be more than 148px away from the edge of an asset. It can be good practice to just keep a template with any and all brand guidelines linked at the top of your brief. And try to look over those brand guidelines with a different perspective: are they clear and comprehensive? Are they actionable? Are they less than 500 pages?

Then, think about reviewers. We’ve run into countless situations in the past where we’ve sent assets to a stakeholder to review, only for them to respond with some variation of “…um, what is this and what am I supposed to do with it?” Oops! It’s important to give stakeholders a heads up about what’s coming their way, and to share the brief with them so they can understand their role. Are they just looking at translated copy, or should they be giving input on creative as well? How much time will they have to review? All of those questions getting answered pre-briefing can save a lot of time and ensure that Frank in Legal doesn’t send you another passive aggressive email.

Know your deliverables

Sometimes, a brief looks something like, here’s our brand guidelines and some photography – we want a social campaign! Which can be a lot more fun to write out than here’s our brand guidelines, we need an entire global campaign for this new product we’re launching. For social, paid ads, and retailers worldwide. And we don’t have translations. By next week thanks!!!!

Regardless of the size of your campaign, breaking down your deliverables into manageable pieces is an invaluable step in your brief creation process, and can massively speed up production timelines. For example, even if you’re looking for a social campaign – what platforms? How many kinds of designs do you want to see? If you have a great relationship with an agency or a team, you often have enough trust in them that they’ll know what to do. But often, what you think might be common sense might be totally foreign to someone who doesn’t know you. It’s always better to be as clear as possible about your expectations, even if those expectations are “I’m not sure yet!”.

Breaking down deliverables into manageable categories is essential:

Social & PPC Ads
- Typically straightforward specs (e.g., Instagram Story vs. Facebook feed).
- Confirm you’ve linked to brand guidelines and platform constraints.
Retailer & E-commerce Assets
- Retailers often have strict file naming, dimension, or brand placement rules.
- Some require hidden disclaimers, legal lines, or additional fields in certain placements.
Out-of-Home (OOH) & Broadcast
- Billboards, transit ads, and TV spots come with their own set of specs—plus heavier legal and clearance requirements.
Localization & Translation
- For global campaigns, specify how many languages/regions, any local brand guidelines, and a process for market sign-off.

At Sherlock, we keep records of common retail platform guidelines, including safety areas, additional logo rules, and file-naming conventions. Those elements go into our briefs, but they also go into reviews, so stakeholders know what to look for. Our creative automation platform, Sherlock Pipeline, also offers features like automated QC of file size, dimensions, color profile, and more.

If you’re dealing with lots of deliverables for your brand, it might be helpful to keep track of common specs so that you can avoid delivered assets getting sent back by the retailer.

Know your goals

As with any marketing endeavor, every project should be tied to some business goal. Knowing what that is – and getting all your stakeholders aligned – will help guide your team if (let’s be real: when) things go awry and you need to make changes to the campaign. A brief doesn’t just have to be instructions; it can also be a source of truth and a guide for everyone involved in the project.

Simple to complex: all the ways to brief

A good brief can shave days (or weeks!) off of a project timeline, but it may require re-thinking what a brief can really be. Rather than a basic overview of what’s needed, a brief can be the main engine of a project, and can even transition to a production tracker if filled out well.

If you’re working on a large-scale campaign, consider using a more robust brief, like the ones we’ve templated for you. They work great for both of these use cases?

Many creative deliverables
- When you actually need assets that must be used somewhere, this is where your brief can get more detailed, and start to look more like a production tracker than just a request for assets. We recommend using a database tool like Google Sheets, Airtable, or Notion, as it will help you stay disciplined and keep track of what’s needed.
Localization
- Translation and localization open a whole new can of worms when it comes to the creative process, which is why we’re providing a totally separate brief for that work. With localization, you often need to consider regional brand guidelines, source translations, and create custom or modularized versions of your marketing collateral for specific retailers and distributors.

For more complex briefs, we’ve found that listing each deliverable as a line item in our brief “database” allows us to clearly see what’s needed, get a quick sense of timelines and action items, and better understand what production data we need to track in order to successfully complete the project. And because we have our briefs templated so well, we’re often running 100+ projects at one time, each with their own brief, tracker, metrics, and desired outcomes. Especially when dealing with translation, managing briefs like production trackers allows us to clearly see what needs to go to our translation partner, what needs to go through the localization process, and what’s more design-oriented.

It's Elementary, My Dear Reader...

The art of writing briefs is tricky, but with large-scale, multi-channel, or global campaigns, a thorough, well-organized brief can save you a world of pain. By treating your brief more like a comprehensive project plan (rather than a quick memo), you give everyone involved the clarity they need to deliver top-notch results.

And remember: not every brief needs maximum detail. If you’re commissioning a strategic shoot or creative concept, you can keep it higher-level. But once production ramps up across multiple agencies or markets, the granularity in your brief becomes your best friend.
