Six ICP Intake Questions to Answer Before Building a Client's First List

Most bad client lists are built from a good-sounding brief. "B2B software companies, 50 to 500 employees, VP and above" fits on one line, fills a list fast, and produces a first campaign where no single email is relevant to everyone who receives it.

The fix happens before anyone touches a data tool. Here are six questions we think an agency should have answered, in writing, before the first list for a new client gets built. They are drawn from public agency onboarding guides and from what tends to break in the first month.

1. Which recent deals did you win, which did you lose, and why?

grobot's onboarding guide asks for the client's last twenty closed-won deals and why each one bought, plus the last ten closed-lost and why. That is a better ICP source than any persona doc, because it is what actually happened.

If the client cannot produce that list, ask for the five best customers they have and what those customers had in common when they bought. Write the answer down. It becomes the evidence the write step uses.

2. What happens right before someone buys?

The same guide calls this the question clients have usually never been asked: the trigger that precedes a purchase. A new hire in a role, a funding round, a product launch, a tool switch, a compliance deadline. Outbound Republic's brief template lists buying triggers and tech stack signals alongside the basics for the same reason.

Triggers do two jobs. They narrow the list, and they give the first email a reason to exist now. They also become candidates for campaign entry signals.

3. Who signs, who influences, and who should never be emailed?

Ask for the titles that actually sign, not the titles the client wishes would sign. Then ask which roles influence, and whether any roles are off limits. Outbound Republic suggests defining a qualified response up front: right seniority, an expressed problem or interest, and authority to make or influence the decision. Agree on that definition now and the first weekly report will not turn into an argument.

4. What disqualifies an account even if it fits on paper?

Outbound Republic's template asks for red flags that disqualify a company even when it matches the firmographics. Push for specifics: business models the client cannot serve, regions they do not sell into, company sizes where deals stall, industries with procurement rules they cannot meet. Disqualifiers are the cheapest list quality tool you have. We wrote about turning them into campaign entry rules.

5. Who must never receive a cold email from us?

Current customers, active opportunities, accounts a partner owns, competitors. grobot puts it well: emailing a client's existing customer as a cold prospect is a recoverable error exactly once. Get the exclusion list as a file, not a promise, and decide who updates it. This is the seed of the client's suppression list, and it should be synced from their CRM where possible.

6. What words, claims, and topics are off limits?

Outbound Republic's brief includes legal or compliance constraints and words the client never uses. Ask what the client cannot claim, which customer names cannot be mentioned, and any regulated language in their industry. This goes straight into the client voice brief.

How to run the intake

• Make it a working session, not a form. grobot is explicit about this. A form gets you "B2B, 50 to 500 employees." A conversation lets you push back until one email could be relevant to everyone on the list.
• Start small. grobot suggests a first list of a few hundred contacts, verified right before send rather than at import.
• Get sign-off on the full sequence. Same source: send the complete sequence to the client for approval before anything goes out in their name. They catch wrong claims about their own product.
• Keep the answers versioned. ICPs drift. When they do, update the brief rather than starting over.

Where GTM fits

GTM finds each client's buyers, qualifies them against that client's ICP, writes from prospect evidence in the client's voice, and sends with a compliance gate, all inside an isolated workspace per client. The six answers above are what that workspace needs on day one.

If you run outbound for several clients, join the waitlist.
