Build a B2B email list from public LinkedIn data
Google Maps finds the companies. LinkedIn people search finds the right people inside them, each with one verified work email. You pay only for the results you keep, and the credits never expire.
How the B2B email list gets built
A B2B email list is only as strong as the two things behind it: the right companies and the right people inside them. CrustAPI keeps those two jobs separate so each half stays accurate, and it pulls both from public, logged-out pages.
Step one is the company side. A Google Maps search returns up to 100 businesses per query with full records: name, address, phone, website, category, hours, rating, and review count. That gives you the target accounts. Maps listings carry no email field, so that is not where the contacts come from.
Step two is the people side. A LinkedIn people search filters by role, seniority, and company, so you get decision makers instead of a whole company roster. Each person you pull comes back with one verified work email from their public profile. That is the piece Maps cannot give you.
You get a clean grid you can drop straight into a spreadsheet, a CRM, or a sequencing tool. No parsing, no scraping infrastructure to babysit.
What each record holds
Every person on the list carries the fields you need to route and personalize outreach, not just an address in a column.
Set next to the usual contact-database tools, the difference is mostly in how you buy and where the data comes from.
| Contact databases | CrustAPI | |
|---|---|---|
| Pricing model | Seat license, annual contract | Pay per result |
| Unused credits | Reset monthly or expire | Never expire |
| Where data comes from | Aggregated, hard to check | Public LinkedIn pages you can open yourself |
| Email per person | Not always included | One verified work email |
| Getting started | Sales call, demo | Self-serve, 3,000 free credits |
The compliance picture
Buyers ask two fair questions about any list like this: where the data comes from, and whether the emails will actually land. Here is where we stand on both.
On the data: US courts have repeatedly sided with collecting public, logged-out pages, while a site's terms restrict automated access on their side. We handle the collection; what you get is data that is public for anyone to see. We do not log in as anyone, and we do not resell someone else's database.
On deliverability: we verify each work email at the moment we collect it, but no provider can promise an inbox will still accept mail weeks later. People change jobs and addresses get retired. Run a quick re-verify before a large send, and follow the sending rules for whatever region you are mailing into. We give you accurate data at collection time, not a guarantee about someone else's mail server.
You want a full sales platform: if you need buying-intent signals, direct-dial phone numbers, and a CRM-integrated sequencing suite in one login, a tool like ZoomInfo or Apollo is the better fit. We build the list and hand you verified emails. We are not a full sales-engagement platform, and for some teams that all-in-one workflow is worth the seat price.
Pricing and credits
One credit equals one result you keep. A search that returns nothing costs nothing, so a tight role filter that finds five people bills five credits, not the whole company.
The free tier is 3,000 credits every month with no card. Paid packs start at 25k for $49, which works out to about $1.96 per 1,000 results, and the rate drops toward $0.40 per 1,000 on the largest packs (100k $149, 500k $549, 2.5M $1,999, and up). Every credit you buy stays on your account until you use it. Nothing resets at the end of the month, and nothing expires.
That matters for list building, because you rarely buy contacts in one clean batch. You test a segment, learn, and come back. With credits that never expire, the budget you spent last quarter is still there to spend.
