What is BookYourData

BookYourData lets you build targeted B2B contact lists by filtering across job title, industry, and location, then verifies each email through an 8-step process before you export. It's built for SDRs, BDRs, founders, and GTM engineers who need clean contact data without committing to a monthly seat fee. The standout capability is its 8-step data verification process, which runs each record through multiple checks — sourcing from public records and third-party providers — before flagging it as deliverable. You can enrich contacts with over 100 data points, push exports directly to Excel, or pipe data into Salesforce, HubSpot, or Outreach via API. The honest limitation: at 10 free credits per month and $0.40 per contact at entry level, costs can add up quickly for teams running high-volume prospecting campaigns without bulk purchasing.

Our verdict

Vanderbuild take

BookYourData is a straightforward prospecting database with built-in email verification — a solid fit for SDRs, founders, and GTM engineers who need verified B2B contacts without locking into a subscription. On the agentic side, an API is available, but agentic readiness is limited — you can pull data programmatically, but expect to hit walls before you've built anything resembling a reliable autonomous enrichment pipeline on top of it. Pricing is free or near-free to test (10 credits/month, no credit card), which makes it low-risk to evaluate against your existing data stack. The main limitation to watch: the free tier is thin for any real prospecting volume, and costs at $0.40 per contact can scale faster than expected if you're not buying in bulk.
