A lead list adds who to contact and why now. This is the order I work in when I turn one of these lists into outbound for a client. 1. **Filter to your ICP:** cut by size band, state, ownership and founding year until every row is a company you would actually sell to. 2. **Score for fit:** have a model read each website and answer the two or three questions that separate good accounts from the rest, then rank. The [TAM calculator](https://getaob.com/tam-calculator) prices this step. 3. **Find the people:** one to three contacts per company in the roles you sell to, through a waterfall of [email finders](https://getaob.com/email-finder-tools) rather than one provider. 4. **Verify every email:** bounces burn sending domains, so every address goes through [verification](https://getaob.com/email-verification-tools), catch-all domains included. 5. **Add a reason to reach out now:** a hiring, funding or licensing event that makes this month the right time. The [buying signals guide](https://getaob.com/buying-signals) covers the types. ## Free lead list vs. buying one vs. building one | | Free company list (this page) | Bought contact list | Built lead list | | --- | --- | --- | --- | | Contacts and emails | No, companies only | Yes, often unverified | Yes, found and verified per company | | Targeting | Industry, size, location | Title and industry filters | Your ICP, scored, with a signal on each account | | Freshness | A snapshot; each list shows its build date | Varies, rarely stated | Pulled the week you send | | Who else has it | Anyone who downloads it | Every other buyer of that list | Only you | | Best for | Sizing a market and seeding a TAM | A quick test | Outbound you plan to run for months | Want the built version?

A lead list is a set of companies or people who fit your ideal customer profile, with enough data to contact them: company name, website, industry, size and location, plus names, titles and verified emails once you add the people. A good one is filtered to your ICP and scored, not just pulled by industry. ### Are these lead lists really free? Yes. Pick a list, enter your first name, work email and company, and you get 1,000 rows as a CSV right away. There is nothing to pay and no account to make. ### Do the lead lists include email addresses? No. They are company lists: name, website, LinkedIn page, industry, size, location and founding year. To turn one into a contact list, find the right people at each company and verify their emails, or have OneGTM do that part. ### How do I build a B2B lead list? Start with a company list for your market, filter it to your ICP by size, location and ownership, score each company for fit, find one to three people per company in the roles you sell to, verify every email, and add a reason to reach out now, such as a hiring or funding signal. ### Is it better to buy a lead list or build one? Bought contact lists are fast but often stale, and every other buyer has the same names. A list built from your ICP, verified before sending and timed by buying signals, takes longer and tends to book more meetings per email sent. ### Where does the data come from? Company records come from the People Data Labs Free Company Dataset (CC BY 4.0). Exact headcount and ownership come from a separate company database and are only attached when the name and size line up. Duplicates, dead companies and rows without a website were removed.
