BookYourData sources its B2B contact data from public business records, licensed data partners, professional directories, corporate websites, and validated contributor updates, then verifies each contact through a multi-step pipeline before delivery.
BookYourData sources B2B contact information exclusively, with no consumer or personal-use data entering the pipeline. Every source meets compliance and verification standards before entering BookYourData's database.
The Five Source Categories
BookYourData's database draws from five source categories: public business records, licensed data partners, professional directories, corporate websites, and validated contributor updates. Each source contributes:
Source | What It Contributes |
Public business records | Company registrations and directory listings open to public search |
Licensed data partners | Contact records supplied under licensing agreements |
Professional directories | Profiles listed in professional and industry directories |
Corporate websites | Job titles and contact details a company publishes itself |
Validated contributions | Contributor updates confirmed before entering the database |
Each category feeds into the same verification pipeline before delivery.
The Verification Pipeline
BookYourData runs every contact through a five-step verification pipeline before the record becomes available for download. The steps run in this order:
Business identity confirmation: confirms the company behind a contact is active.
Domain validation: checks that the company's email domain is live.
SMTP verification (real-time): confirms the mailbox accepts mail at the moment of the check.
Bounce-rule screening: removes addresses matching known bounce patterns.
Update checks across partner and public datasets: cross-checks the record for recent changes.
The verification pipeline supports BookYourData's 97% deliverability guarantee, with credits refunded for records outside that rate.
Refresh Cycle
BookYourData refreshes contact records on a rolling cycle of 30 to 90 days, with the exact interval set by job role and industry dynamics.
The refresh cycle keeps a downloaded list closer to current job titles than a list built once and never rechecked.
