Questions to Ask a Marketing Agency Before You Sign: The Founder’s First Call Checklist

Cory Warren·October 27, 2026

If an agency has burned you before, you’re not alone, and you’re not being paranoid. Most founders we talk to have a story like this: a polished pitch, a senior strategist who disappeared after kickoff, and monthly reports full of reach and engagement that never showed up in the bank account. This guide gives you the questions to ask a marketing agency on the first call. For each one, we cover what a good answer sounds like and the red flag that should end the conversation.

We should be upfront: we run an agency, so we have a stake in this. Even so, we’d rather you hire the right partner, even if it isn’t us, than go through another bad experience that puts you off outside help for good. This checklist is written for founders running brands at around $2.5M, where every hire and every dollar has to earn its place.

Why Founders Distrust Agencies (and Why Some of That Is Earned)

The stigma didn’t come from nowhere. Setup runs an annual Marketing Relationship Survey, and in its latest edition the #1 reason clients end agency relationships is dissatisfaction with delivery, cited by 48% of clients, up 14 points from the prior year. Right behind it, “agency didn’t understand the business” tied for second place among clients (Everything PR’s summary of the survey data).

Agencies, on the other hand, tell themselves a different story. In the Setup survey results, agencies said clients leave mainly because of client budget cuts (75%) and change in client leadership (55%). Only 3% named not understanding the client’s business. Put simply, clients are saying “You didn’t deliver. You weren’t worth the cost. You didn’t understand us.”

To be fair, plenty of agencies get this right. One joint study by the 4A’s and the ANA found that 90% of Clients prioritize overall value and long-term ROI over cost when engaging with an agency, and long, productive partnerships really do exist. The hard part is spotting a good partner before you sign, not six months and a lot of cash later. That’s the job of this checklist.

Scripted Sales Answers vs. Owner Thinking

Every question below tests one thing: is this person reading from a script, or are they already thinking about your business the way you do? Once you know the pattern, it’s easy to spot.

Signal	Scripted sales answer	Owner thinking
Focus	Talks about their services, awards and logos	Asks about your margins, cash flow and repeat rate
Success metrics	Reach, followers, platform reported returns	New customer revenue, contribution margin, total marketing efficiency
The plan	A full proposal in the first meeting	“We need to see your numbers before we recommend anything”
Bad news	“That won’t happen with us”	“Here is what we do when it does”
The team	“Our team” in general terms	Names, roles and an offer to meet them
Scope	Sells everything on the menu	Tells you what to skip for now

Here’s a quick test. Imagine swapping your brand name for someone else’s. If the answers wouldn’t change, you’re listening to a script.

What to Have Ready Before You Ask Anything

You’ll get better answers if you bring a few numbers. You don’t need a polished deck. A one page summary is plenty:

Your gross margin after shipping, fulfillment and discounts
Roughly what you can afford to pay to acquire a new customer
Your repeat purchase rate and how quickly second orders come in
What you’ve tried that didn’t work, and why you think it failed

If you’re unsure about the efficiency side, start with our guides to MER vs ROAS and calculating your break-even ROAS. An agency that asks for these numbers is a good sign. One that never asks is telling you something, too.

The Founder Checklist: 10 Questions to Ask a Marketing Agency on the First Call

You can work through these in order or pick the ones that matter most to you. Pay attention to how people answer, not just what they say. Pauses, specific details and an honest “we don’t know yet” usually tell you more than a polished reply.

1. “What do you need to know about our business before you recommend anything?”

This shows whether they diagnose before they prescribe. A $2.5M brand can grow in a dozen directions, and most of them don’t fit your margins or your cash position.

What a good answer sounds like: They ask about contribution margin, inventory, cash flow and which products actually make money. They want to see your data before they form an opinion.
Red flag: A full channel plan in the first ten minutes, before they know anything about your unit economics.

2. “Who will work on our account every day, and can we meet them before we sign?”

An agency is only as good as its people. Pitch teams are often an agency’s strongest talent, and that’s fine, as long as you know who you’ll actually work with after the contract is signed.

What a good answer sounds like: Names, roles, relevant experience, how many other accounts each person handles, and an offer to bring the day to day lead to the next call.
Red flag: Talk of “the team” with no names, or pushback when you ask to meet the people doing the work.

3. “How will you define success, and what will you report to me each month?”

This is where vanity metrics either show up or get ruled out. Your reports should connect to the profit and loss statement, not just to an ad dashboard.

What a good answer sounds like: Success is tied to new customer revenue, acquisition cost compared with what you can afford, efficiency across all your marketing spend, and profit. They agree the target with you upfront.
Red flag: Impressions, followers or engagement as the headline result. Those numbers can help diagnose problems, but they aren’t business results.

4. “Tell me about a time you told a client to spend less with you.”

This is the integrity question. Any experienced agency has advised a smaller scope, paused a channel that wasn’t working, or told a client to fix the offer before spending more.

What a good answer sounds like: A specific story: what they saw, what they recommended, and what it cost the agency.
Red flag: They can’t think of an example, or they turn the question into a humble brag.

5. “If you could only do three things for us in the first 90 days, what would they be, and what would you skip?”

Lean teams can’t do everything at once. Deciding what comes first is the strategy, and choosing what to leave out is the hardest part.

What a good answer sounds like: A short list, each item tied to your biggest constraint, plus a clear “we’d hold off on this for now.”
Red flag: Every service on the menu, all starting right away.

6. “How do you make sure we’re paying to reach new customers, not people we already have?”

One of the quietest ways to make results look better is to spend heavily on ads shown to past buyers and email subscribers who would have bought anyway. The ad platform report looks great. Meanwhile, your real acquisition cost goes up, because you’re paying for the same customer more than once.

What a good answer sounds like: They separate new and returning customer revenue, exclude existing customers where it makes sense, and judge success by growth across the whole business rather than by how much credit a platform claims.
Red flag: They’re proud of their retargeting results but don’t mention new customer growth.

7. “If we part ways, what do we own?”

Ask this on day one, while everyone is still friendly. Meta, for example, lets you add partners (for example, other businesses or agencies) to your own business account (Meta Business Help Center). This matters because whichever portfolio creates or claims an asset owns it. If an agency sets up your ad account inside its own portfolio, you could end up walking away from your own ad history, including every audience and every conversion record (Inflowave).

What a good answer sounds like: “You own everything”: ad accounts, tracking, analytics, creative and customer lists. They work through partner access that you control.
Red flag: Ad accounts set up under the agency’s business, or creative usage rights that end when the contract does.

8. “What happens when results dip?”

At some point they will. How an agency handles a bad month says more about it than any case study. Research from AAR found that trust is not broken by an honest mistake. Especially if the mistake is owned up to!

What a good answer sounds like: You hear about it from them first, along with what they’re investigating and how quickly they’ll adjust.
Red flag: “That won’t happen with us.”

9. “What will you need from us to succeed?”

Good partnerships go both ways. An agency that’s honest about what it needs from you is planning to work with you, not around you.

What a good answer sounds like: Fast approvals, access to data, notice of inventory changes, product samples and one clear decision maker.
Red flag: “Nothing, we’ll handle it all.” That usually means they don’t understand your business or plan to run it on autopilot.

10. “Can we speak with a current client, and with one who left?”

Any agency can produce one glowing reference. What you want to see is how they talk about the relationships that ended.

What a good answer sounds like: Happy to connect you with clients of a similar size, and a frank explanation of why some clients moved on.
Red flag: One hand-picked reference and defensiveness whenever churn comes up.

Vet the People, Not Just the Pitch

If you take one thing from this checklist, make it this: you’re hiring people, not a logo. Setup, which has studied a decade of agency pitches, notes that clients value chemistry over capability most every time. But chemistry with a pitch team you’ll never see again doesn’t help you.

Turnover matters too. AAR’s research found that, on the agency side, trust is threatened by changes in the account team, multiple departures, pitching and new clients to service (AAR Group). So treat this like a key hire. Talk to each person who will touch your account, and ask what they’d do if they were in your seat.

Finally, ask yourself whether each person you meet would go above and beyond for your brand. We don’t mean as a slogan. We mean the strategist who points out an inventory problem they spotted, even though it’s outside their scope. The best agency people think like owners because they care how the story ends.

How to Hire a Marketing Agency Without Repeating Past Mistakes

Score each agency right after the call, while it’s fresh. Five honest questions will tell you most of what you need to know:

Did they ask more about my business than they said about themselves?
Did I meet, or get a firm commitment to meet, the people who would do the work?
Did they define success in terms of revenue and profit?
Did they recommend not doing something?
Did any answer sound like it would work for any brand?

Read the contract just as carefully. In a Digiday survey of client side marketers, twenty-six percent of marketers ended agency work due to hidden fees 29% due to overbilling. Ask what fees sit outside the retainer and how ad spend is billed. A good partner will put this in writing in plain language.

Where C4 Stands on All of This

At C4 Social, we take real pride in doing what’s right for the client, no matter what. Sometimes that means recommending a smaller scope or pausing a channel that isn’t paying back. Other times it means telling a founder to fix their product pages before spending another dollar on traffic, which is exactly why we wrote our Shopify conversion rate optimization checklist. Those calls aren’t always the easiest or most profitable path for us, but they’re the right ones.

In a full-service growth partnership, our job is to see the business the way you do: margins, cash, retention and the long game. That’s also why we’ll ask you to meet the people who would actually run your account, not just us. We’d rather earn next year than squeeze next month.

FAQ: Questions to Ask Before Hiring a Marketing Agency

How many agencies should I talk to before hiring?

In our experience, two to four serious conversations is usually enough. Fewer leaves you with nothing to compare. More tends to blur together, and every hour you spend on calls is an hour away from running the business.

What is the biggest red flag when hiring a marketing agency?

An agency that talks more than it listens. If they never ask about your margins, customers or cash flow, they can’t build a plan around your business. Being vague about who will do the work is a close second.

Should I choose a specialist or a full-service agency?

It depends on where your growth is stuck. If one channel is the clear bottleneck, a specialist can make sense. For relationship length, the ANA and 4As found that integrated full-service agencies report an average tenure of 87 months (7.3 years), while media-only agencies have a significantly shorter average tenure of 44 months (3.7 years) (ANA).

How soon should I judge an agency’s performance?

Give results a reasonable runway, because testing and learning take time. However, you can judge communication, honesty and thinking from the very first week. Those early signals usually predict how the results will go.

Should an agency guarantee results?

Be careful with guarantees. Results depend on your product, offer, margins and market, and no outside partner controls all of those. A trustworthy agency will commit to a clear process, honest reporting and shared targets instead.
