What to Put in a Custom Lead-List Brief: Industry, Role, Geography and Size

Off-the-shelf lead packs cover a lot of ground, but sometimes your target market is narrow enough that a custom list is the better fit. A custom list is only as good as the brief behind it. Vague briefs produce files that look impressive and go nowhere; a specific brief produces a list your team can actually work through.

Here is the structure we suggest for a custom lead-list brief, field by field.

1. Lead with the campaign, not the count

Open with two or three sentences: what you sell, who usually buys it, and what you want to happen after first contact — a reply, a booked call, a demo. Then state roughly how many new contacts your team can realistically follow up each week. That number, not the size of the budget, should shape the request. If you are still deciding between a fixed pack and a recurring flow, our comparison of one-time packs and monthly subscriptions is a useful starting point.

2. The four core filters

Industry (and sub-industry)

"Technology" is not an industry for targeting purposes — it is a category that hides a dozen different buyers. Narrow it to the sub-segment you actually serve: logistics software for freight forwarders, payroll services for restaurants, and so on. The more specific the sub-industry, the less noise you pay for.

Company size

Give headcount and/or revenue bands, and say which one you mean. A 20-person firm and a 2,000-person firm buy differently, budget differently and answer the phone differently. If you sell to both, say so and expect the message to differ by segment.

Geography

Country, region, city and language. "Europe" and "LATAM" are regions, not geographies — decide the countries. If you need a specific language or a local phone format, say it in the brief.

Business role

Job titles vary from company to company. Give the role you want to reach (for example, operations manager), plus three to five title variants and the seniority level. Also say whether you want one contact per company or several — that single choice changes the shape of the file.

3. The qualifiers that save the most time

• Exclusions. Competitors, current customers, and anyone on your do-not-contact list. Send the domains or emails explicitly rather than describing them.
• Required fields. Which columns must be populated: email, company name, domain, role, country — and phone if your team calls.
• Optional signals, only if they can genuinely be sourced: hiring activity, recent funding, a new location. If a signal cannot be verified, leave it out of the brief rather than accept a guess.

4. Format and delivery expectations

Ask for CSV or Excel, one row per contact, with clear header names and a stated encoding. Ask whether the file will include source and collection dates as columns. A file without dates ages badly: you cannot tell whether a record is three weeks or three years old, and you cannot judge how much of it is still worth working.

5. Ask what "verified" means

Ask directly: which check was run, when, and what the check does not cover. A verified email is not a promise of delivery, a reply or a sale. Ask how duplicates are handled inside the file, and whether the list can be checked against a previous delivery so you are not paying twice for the same contact.

6. Questions to ask before you commission

1. Which fields are guaranteed to be populated?
2. What does verification cover, and when was it run?
3. How are duplicates handled within the file and against earlier deliveries?
4. Can you exclude a list of domains or emails that I send you?
5. What format, encoding and column names will the file use?
6. Is the price a fixed quote or a range?
7. What is the process if a field is missing or wrong?
8. Can you describe the source category behind each record?

The answers tell you more about fit than any headline count.

7. A fictional example brief

Fictional example, for illustration only — not a real customer.

A 15-person accounting-software company sells to finance teams at mid-sized logistics firms in Mexico and Colombia. Their brief: companies with 50–500 employees; contacts in finance manager, finance director and controller roles, three title variants; one contact per company; exclude three named competitor domains and their existing customer list; CSV with company, domain, contact name, role, country, city and collection date; roughly 120 new contacts per month; six hours a week of follow-up capacity across two people. That brief is specific enough to quote, build and check.

8. After the list arrives

Before anything goes into your CRM, run the file through a short import routine: map fields, deduplicate, record the source and date, and test a small batch first. Our CSV/Excel import checklist walks through that step by step.

Next step

If a fixed pack does not match your market, a custom list built from a brief like the one above is the alternative — see the current options on our store page. Custom work is quoted per project, so the brief is also the fastest way to get a useful answer on scope and price.
