How to Write a Marketing Proposal (Template + Example)

A business wants more leads, more sales or more subscribers, and they’ve asked you for a proposal. They’ll probably get two or three, and most will read like a list of services with a price at the bottom.

To write a marketing proposal, start with the client’s goal in their own words and turn it into numbers you’ll report on. Then explain the channels you recommend and why, list what’s included and what isn’t, set the timeline and reporting, and price it as a monthly fee with the ad spend shown separately. Add one result from a similar client and end with a clear way to accept.

We make proposal software, so we see what happens after agencies hit send. In 2025, agencies sent 4,356 proposals through Nusii, and 47.7% of them were accepted. This guide covers each part of a marketing proposal, with a full example and what our data says about the ones that win.

What is a marketing proposal?

A marketing proposal is the document you send a prospective client to win their marketing work. It shows you understand their goal, explains the strategy you’d follow, sets out what’s included and what it costs, and gives the client a way to say yes.

A marketing plan is something else: the detailed strategy, often written for the business’s own team. A proposal sells that strategy to a client, so it needs only enough of the plan to show you know how to get there. Many agencies write the full plan as the first paid piece of work, once the client has signed.

Kai Davis, one of the consultants we interviewed for our book, The Creative Professional’s Guide to Better Proposals, sums up what a proposal is for: “Proposals are a way to communicate value and reduce risk.” The client needs to see what the work is worth to them, and why they can trust you with it.

What to include in a marketing proposal

Most marketing proposals have the same eight parts, in this order. Use them as your template:

The lines come from a proposal that Northbound, a fictional agency, wrote for Lantern Tea, a fictional online tea shop with a subscription box. You’ll find the whole proposal further down.

If you’d rather start from a finished document, our free templates already have these parts in place: digital marketing, social media, SEO and content marketing.

How to write a marketing proposal in 7 steps

Step 1: Have the discovery call before you write anything

Nathan Powell, Nusii’s co-founder, wrote in our book that “99% of all proposals are written during your client meetings.” A proposal written from a three-line email is a guess, and it reads like one.

On the call, find out:

• The goal behind the request. “We need more Instagram followers” usually means more sales or more bookings. Ask what happens to the business if nothing changes.
• The numbers today. Traffic, leads, sales, the cost of each new customer and where they come from. You need a starting point to show progress against.
• What they’ve tried. Past agencies, and the channels that didn’t work and why. It tells you what they’ll be skeptical about.
• The budget for your fee and for ads. A range is enough. If they hesitate, offer brackets: “Are we looking at $2,000, $5,000 or $10,000 a month?” Our guide on asking about the budget has more ways to ask.
• Who approves it. The marketing manager may love your plan and still need the founder or finance to sign.
• What they’ll judge you on. The number they’ll check in three months: sales, booked calls, cost per lead.

Ask, too, why they don’t do it in-house. It can feel like talking them out of hiring you, but the answer tells you what they’re paying for: time, expertise or an outside view.

End the call by agreeing when you’ll send the proposal, and book a short call to go through it together. Our client interview guide has the full set of questions.

Step 2: Title it with the client’s goal, then open with their situation

The title is the first line the client reads. “Marketing proposal for Lantern Tea” tells them nothing they didn’t know. “How Lantern Tea can reach 1,000 subscribers by June” tells them what you’re proposing before they’ve read a word of it.

Then write an overview of three to five sentences: where the client is now, what they want and why it matters now. Use the words they used on the call, so they recognize their own problem. Your agency’s story can wait until the proof.

Clients read this part quickly, often before you’ve spoken again. Of the agency proposals that clients opened in 2025, half were opened within 54 minutes of being sent. Here’s Northbound’s overview:

Step 3: Turn the goal into numbers you’ll report on

A goal like “grow our brand” can’t be met or missed, so the client can’t tell whether you did a good job. Agree on two or three numbers, each with a starting point, a target and a date, and say where you’ll measure them:

• 1,000 active subscribers by 30 June, up from 620.
• New subscribers at $30 or less each in ad spend, down from $45.
• A quarter of new subscribers from email and referrals by June.

If the work is hard to measure, like brand awareness, pick the closest number you can track, such as branded searches or direct visits. Only promise results you control. For the rest, commit to the work and to reporting the number, and explain what moves it.

Step 4: Explain your strategy in plain language

Now show how you’ll get the client there. Name the channels you recommend, say why each one fits this client and describe what you’ll do on it. Leave out the channels you don’t recommend, or give them one line with the reason.

Write for the person who signs, who may not know what ROAS or a lookalike audience is. Compare these two descriptions of the same work:

• Hard to follow: “Full-funnel paid social with lookalike audiences, DPA retargeting and CBO testing.”
• Easy to follow: “We’ll show ads to people similar to your best subscribers, remind visitors who looked at the tea box, and move the budget each week to the ads that bring in subscribers for under $30.”

Mojca Mars, a social media consultant we interviewed for the book, wants her proposals “very goal-oriented, without any unnecessary fluff and easy to read.” Keep the detailed media plan for the first month of work.

The strategy should also summarize what you discussed on the call, so nothing in it surprises the client. If you have a new idea, talk it through with them before it goes in the proposal.

Step 5: Define the scope, timeline and reporting

Marketing work has no natural end, so scope creep can start in the first week. A scope that says exactly what the fee covers each month protects your margin and the relationship. List three things:

• What’s included: the number of campaigns, ads, posts, emails or articles a month, plus reports and meetings.
• What isn’t: photography, influencer fees, website changes or extra channels. Offer the ones you can do as add-ons.
• What you need from the client: access to their accounts, product photos and other assets, one person to give feedback, and how fast they’ll approve new work.

Approvals are where most marketing timelines slip, so agree on a turnaround, such as two working days, in the proposal.

Then add the timeline: when each part goes live, and when you’ll report and meet. For a retainer, a monthly report and a 30-minute call are typical. Give the dates in weeks from the start, so the plan still works if the client signs later than you expect.

Step 6: Price it: your fee, the term and the ad spend

Most marketing work is priced in one of three ways:

• A monthly retainer for ongoing work such as ads, SEO, social media or content. Set a minimum term and say what happens after it.
• A project fee for work with an end, such as a launch campaign, a strategy or an audit.
• A percentage of ad spend for paid media, usually with a minimum monthly fee.

Whichever you use, show the ad spend separately from your fee: how much you recommend and who pays the ad platforms. Clients compare agencies on the fee, and a total that mixes the two makes yours look bigger than it is.

Monthly fees take more convincing. In 2025, proposals with a recurring fee were accepted 44% of the time, against 55% for proposals without one. A smaller first commitment helps: a three- or four-month minimum instead of twelve, or a paid audit before the retainer. Philip Morgan, another consultant in our book, recommends proposing “the smallest possible increment of improvement” and growing the work from there.

What about packages? Our data says use them with care. Proposals with options the client could choose were accepted less often than proposals without (38% against 57%), and the gap held within the same businesses. When clients did accept, a quarter of them picked a total above the one they were first shown. So give options when there’s a real choice to make, for example when the client hasn’t settled on a budget. Keep it to two packages, mark the one you recommend and add extras as optional items.

In Nusii, a price can be fixed, recurring, per item or a range, and the client can pick between packages or tick optional items in the proposal itself, with the total updating as they choose. You’ll see how Northbound priced its proposal in the example.

Step 7: Add proof and make it easy to say yes

One result from a similar client does more than a page of awards: where they started, what you did and the number it moved. Add who will do the work. The client is hiring people as much as an agency.

Then end with one next step: how to accept, by when, and what happens the day they do.

Let the client accept and sign in the proposal itself, so a yes doesn’t wait for a printer and a scanner. Before you send it, read it once as the client would. Our proposal checklist has the final checks.

Marketing proposal example

Here’s the whole proposal Northbound sent Lantern Tea, with every part from the steps above. The agency, the client and the numbers are made up.

It leaves out the agency’s history and its full list of services. Every part answers a question Lantern Tea’s founder will have, which keeps it short. Short proposals did better in our data too. The proposals accepted through Nusii in 2025 had a median of 7 sections, and the ones that weren’t accepted had 9.

What our data says about marketing proposals that win

For our State of Proposals 2026 report, we looked at every proposal first sent through Nusii in 2025. Here’s how fast agencies’ clients opened and signed:

Five findings for anyone writing marketing proposals:

• Agency clients take a little longer. Half of the accepted agency proposals were signed within 4.2 days, against 3.1 days for all proposals, and 15% were signed more than a month after they were sent. Don’t give up on a proposal after a week.
• Past clients say yes most. Proposals to a client who had accepted an earlier one were accepted 72% of the time, against 44% for everyone else. Your next retainer may well come from a client you already have.
• Following up pays. Proposals sent a second time, as a reminder or a revised version, were accepted 58% of the time, against 48% for the ones sent once.
• Shorter proposals won. Accepted proposals had a median of 7 sections, and the rest 9.
• Images and video didn’t help. Proposals with images were accepted less often than those without (45% against 59%), and proposals with a video less often again (39% against 52%). Mood boards and showreels belong in your portfolio, which the client has usually seen before they ask for a proposal.

These are associations, not proof of cause: a proposal to a past client is often a quick renewal, and a proposal with a video is often a bigger pitch. They point the same way as our book, though: short, clear proposals about the client’s goal.

When to follow up on a marketing proposal

From the numbers above, a simple plan:

• Not opened after two days: check that it arrived. Three in four agency proposals are opened within a day, so yours may be in a spam folder or with the wrong person.
• Opened, no answer after four days: by then, half of the accepted agency proposals have been signed. Send a short note and offer to go through it on a call.
• No answer after two weeks: 74% of the accepted ones are signed by then. Ask whether the timing or the scope has changed, and offer a smaller first step.
• Still nothing after a month: close the loop politely. Blair Enns’s line, which Nathan shares in our book, still works: “I haven’t heard back from you on [project] so I’m going to assume you’ve gone in a different direction or your priorities have changed.” In Nathan’s experience, many clients reply to it.

Nusii emails you when a client opens your proposal, so you know when to follow up. Our follow-up email templates give you the words.

Types of marketing proposals

The structure stays the same from one kind of marketing proposal to the next. What changes is the strategy, the scope and the numbers you report on:

• Digital marketing proposal: paid search and social, analytics and reporting, usually on a monthly retainer. Start from our digital marketing proposal template.
• Social media marketing proposal: the platforms, a content calendar, community management and paid social. See our social media proposal template.
• SEO proposal: an audit, technical fixes, content and links, measured in rankings, traffic and leads. See our SEO proposal template.
• Content marketing proposal: the strategy, the number of articles or videos a month and where they’ll be shared. See our content marketing proposal template.
• Email marketing proposal: list growth, automated emails and campaigns, measured in revenue or sign-ups. The digital marketing template works as a starting point.
• Branding proposal: positioning and identity work, often before the marketing starts. See our branding proposal template.

Common marketing proposal mistakes

• Writing it before the discovery call. Without the client’s numbers and budget, the proposal is a guess, and the client compares you on price.
• Selling tasks instead of results. “Five posts a week” is a task. “40 booked calls a month from LinkedIn” is a result. Lead with the result, then explain the tasks that get there.
• Writing in jargon. CPM, ROAS and CBO mean nothing to many of the people who sign. Say what the work does for the business.
• Leaving the scope open. “Social media management” without the platforms, the number of posts and the approval process leads to arguments by the second month.
• Mixing ad spend into your fee. The client sees one big number and compares it with an agency that quoted the fee alone.
• Writing about yourself. Your history and every service you offer push the plan and the price further down. Keep the proof to one or two relevant results.
• Ending without a next step. A proposal without a way to accept and a date to decide by tends to wait.
