How to Choose a GTM Agency: 12 Questions to Ask Before You Sign

Picture a founder who has just sat through 3 agency sales calls in a week. All 3 promised qualified meetings. All 3 showed impressive dashboards. One offered a guarantee. The founder signs with the one that sounded most confident, and 3 months later discovers the agency owns the domains, the lists and the inbox history, and none of it comes with them if they leave.

Choosing a GTM agency is hard because the pitches sound alike. The differences show up in the details: how targeting is built, who approves what goes out, and who owns what when the contract ends.

This article gives you 12 questions to ask any GTM or outbound agency, what good answers sound like, the red flags, who should own the domains, lists and data, how pricing models compare, and how Oriel would answer the same questions.

What a GTM Agency Does

GTM stands for go-to-market: everything a company does to find, reach and win customers. A GTM agency runs some part of that for you. Most focus on outbound, meaning reaching buyers who have not contacted you yet, through cold email, LinkedIn and sometimes calls.

The work usually includes targeting, list building, sending infrastructure, copy, sending, reply handling and reporting. Some agencies also build systems, such as signal tracking and CRM workflows, which is closer to GTM engineering. We explain the difference in What Is GTM Engineering?.

How to Run the Selection

The process matters as much as the questions. Ask every agency the same things, get the answers in writing and compare them side by side.

The 12 Questions

Here are the questions, what a good answer sounds like and the red flag to watch for.

Questions 1 and 2: targeting and signals

Good agencies can explain their targeting in plain language. Ask to see how they would split your market. If the answer is a database size, they are selling volume. A good answer mentions specific signals, such as a new sales leader, a funding round or a job post for the role you serve, and explains why each one fits your buyer.

Question 3: approval

Every lead list and every first message goes out in your name. You should approve them before they send. An agency that resists this is asking you to trust it with your reputation without checking. We explain where sign-off matters in Human Approval in AI Outreach.

Questions 4 to 6: infrastructure and deliverability

Cold email should never go out from your main company domain. It should use separate sending domains and warmed inboxes. A cold inbox sends about 40 emails a day after warmup, which takes about 2 to 4 weeks, so volume comes from more inboxes. Since February 2024, Gmail and Yahoo have required bulk senders to authenticate with SPF, DKIM and DMARC and to keep spam complaints below 0.3%. An agency promising thousands of emails in week 1 is either using someone else's infrastructure or about to damage yours. See How Many Domains and Inboxes Do You Need for Cold Email?.

Questions 7 and 8: research and replies

Ask to see an example research brief and an example first message. Ask who reads and answers replies, and how fast. A warm reply answered by a template a day later is a lost meeting.

Questions 9 and 10: reporting and testing

Opens and emails sent describe activity. Positive replies and meetings per list and angle describe results. Ask how they test copy and how many sends they wait for before judging. We cover a testing method in How to Test Cold Email Copy.

Questions 11 and 12: exit and promises

Ask what you keep if you leave next month. Then ask what they promise, and listen for whether the answer is honest.

Honest answers about results usually sound modest. They describe what the first month will produce in terms of setup, lists, approved messages and first replies, and give ranges for later months that depend on your market and offer. An agency that names a precise number of meetings before it has seen your ICP, your offer or your past outreach is guessing, or planning to count meetings loosely.

Once you have the answers from 3 agencies, put them side by side in one table. The differences are usually obvious within a few minutes.

Who Should Own Domains, Lists and Data

This deserves its own section, because it is an issue buyers often discover too late.

You should own:

• Sending domains, registered in your company's name or accounts.
• Inboxes, created in your email provider, with the agency given access.
• Lead lists, stored in your CRM or your own files.
• CRM records and activity history, in your CRM.
• Workflows and automations, built in tools you hold the account for.

A simple test: ask the agency to describe, step by step, what happens on the day you end the contract. A good answer is short. They remove their own access, and everything else is already yours, in accounts you control, with nothing to export or transfer. A vague answer, or one that involves paying for an export, tells you who really owns the work.

Warmed domains take weeks to build. Lists and reply history are expensive to recreate. If they sit in the agency's accounts, ending the contract means starting from zero. Ask for ownership terms in writing before you sign.

Clean data also matters once it is yours. The CRM hygiene play shows how to keep records usable as outreach scales.

Pricing Models and Their Tradeoffs

Done-for-you outbound programs for this workload commonly run $5k to $15k/month, plus roughly $500 to $1,000/month in data and sending tools. How that money is structured changes the incentives.

Retainer

A fixed monthly fee for an agreed scope. It funds steady work and lets the agency invest in setup. The risk is paying for months without a clear review. Agree goals and a review date up front.

Pilot

A fixed fee for a short, defined period, often a month. It limits your risk and forces the agency to show progress. The risk is a pilot too short to judge: inboxes need 2 to 4 weeks of warmup, so a very short pilot may end before real sending starts.

Per meeting

A fee for each booked meeting. It looks low-risk because you pay only for results. The risk is in the definition of a meeting: the incentive is to book as many as possible, and a meeting with a poor-fit buyer still counts unless the contract says otherwise. If you go this route, define a qualified meeting precisely.

For context on what you are comparing against, one US SDR costs about $100k to $200k a year fully loaded, with a ramp commonly 3 to 6 months. The full comparison is in AI Sales Team vs Hiring an SDR.

Checking Proof Before You Sign

Answers on a sales call are a start. Before signing, ask for evidence that matches the answers.

Ask to see real work

Request an example lead list with the signal and source for each row, an example research brief and an example first message. Names can be hidden. If an agency cannot show any of these, it may not produce them for you either.

Ask how results are described

Look at how the agency presents its own results. Clear claims say what was measured and over what period. Vague claims such as "millions in pipeline" with no definition are hard to check. Pipeline, meetings and revenue are very different numbers, and a good agency will say which one it means.

Ask who does the work

Find out who will build your targeting, who will review messages and who will answer replies. Ask whether the person on the sales call will be involved after you sign.

Ask for a first-month plan in writing

A good agency can tell you what happens each week of the first month. For example: targeting and domain setup first, lists and drafts for your approval next, first sends after warmup, and replies and a review at the end of the month. If the first month is vague, the rest probably will be too.

Red Flags in One List

• Sending from your main domain.
• No approval step for lists or messages.
• They own the inboxes, domains or lists.
• High volume from the first week.
• Targeting explained as database size.
• Reporting on opens and sends only.
• A guaranteed number of meetings without a strict definition of qualified.

FAQs

Hold Every Agency to These 12 Questions, Starting With Oriel

Here is how we answer them. You approve every lead list and every first message before anything sends. We never send from your main domain: sending runs on separate domains and warmed inboxes, and everything, including the CRM, domains, inboxes and lists, sits in accounts you own. We report positive replies and meetings per list and angle every week, and we do not guarantee meetings, because a guarantee rewards volume over fit.

On a 30-minute call, ask us all 12 questions and hold us to the same table you use for everyone else. We will tell you how we would target your market and what the first month would look like. If you are not ready for this yet, we will tell you that too.
