B2B Sales Prospecting Data — 76M Verified Contacts

Why bad B2B contact data costs more than you think

Bad contact data does not just mean bounced emails. It means your SDRs spend their first hour every morning triaging delivery failures. It means your Marketo or HubSpot domain reputation drops every time a campaign goes out on a stale list. It means your sender score falls quietly, campaign by campaign, until deliverability becomes structurally broken.

The US B2B contact market decays at roughly 25 to 30 percent annually. Job titles change. People move companies. Email addresses go dark. A list that tested well 18 months ago may now have a 30 percent bad address rate — more than enough to trigger spam filters on a large send.

EmailAddress.ai builds its B2B database from 43 verified global sources, with cross-source validation on every record before delivery. The result is 99.3% multi-source enrichment accuracy and 98%+ professional email coverage on US contacts — not a single-source extract with a marketing claim attached.

Use Cases

How sales and marketing teams use this data

Revenue Operations — CRM enrichment at scale

A Revenue Ops team at a mid-market SaaS company running Salesforce has 180,000 accounts in the CRM with 40 percent missing job titles and 30 percent outdated emails. Appending from the EmailAddress.ai B2B database fills missing titles, emails, LinkedIn URLs, and company revenue data across matched records. Match-and-append pricing scales to volume. No full-list replacement required.

SDR and BDR teams — prospect lists by industry and title

Filter 73.9 million titled US contacts by NAIC industry code, company size, state, and job function. A BDR team targeting mid-market financial services firms in the Midwest can pull 15,000 director-and-above contacts with verified email, phone, and LinkedIn — delivered as a CRM-ready file within two business days.

Marketing Operations — campaign lists with verified email

74.8 million US contacts have verified professional email addresses. On verified lists, bounce rates stay below 3%, protecting sender reputation in HubSpot, Marketo, and Salesforce Marketing Cloud. Job title coverage at 97% enables persona-based segmentation without manual list cleanup.

Market intelligence and data teams

505,333 unique US business services companies, 581,713 health services firms, and 491,780 engineering and professional services firms are queryable by geography, company size, and NAIC code. Teams building market sizing models, territory plans, or competitive landscape analyses use the database as a structural data layer.

How the B2B database is built and maintained

43 verified global sources — Business registries, professional network feeds, company directories, event attendee data, and opt-in publication networks. No single source exceeds 30 percent of any regional dataset, which prevents single-source data quality failures from affecting the full file.

Cross-source validation — Company, title, and contact fields are validated across multiple sources before a record is included. The 99.3% enrichment accuracy figure is a cross-validation score, not a single-source pass rate.

Quarterly refresh cycle — B2B contact data is refreshed every quarter. Each delivery is timestamped. US and UK records include verified professional email at each refresh.

Catch-all domain resolution — Corporate email domains configured as catch-all servers accept all incoming mail regardless of whether the mailbox exists. EmailAddress.ai's verification infrastructure resolves catch-all addresses to deliverable or undeliverable status before delivery via our catch-all email verification. This is the difference between 98%+ email coverage and a list with unresolved catch-all addresses inflating the apparent coverage rate.

How B2B data licensing works

One-time licensed extract — CSV or Excel file delivered to secure FTP or cloud storage. Includes data dictionary, field mapping, and NAIC classification reference. Standard for campaign and CRM upload use.

API access — Query by industry, geography, company size, or job title. Built for CRM enrichment platforms, sales intelligence tools, and marketing automation systems.

Recurring quarterly delivery — Scheduled delivery at each quarterly refresh cycle. Recommended for revenue operations teams that need current contact data on an ongoing basis rather than a one-time extract.

All B2B data licenses include lawful-basis documentation for GDPR (UK and EU records), CCPA applicability tagging (California records), and CAN-SPAM opt-out suppression support on request. Learn more on the B2B Data Licensing page, see our global coverage, or review our data methodology.

Frequently asked questions

What is B2B data licensing?

B2B data licensing is an arrangement where a company purchases a defined set of professional contact records for a specific use case — outbound sales prospecting, CRM enrichment, market research, or campaign execution. Unlike a one-time list purchase, a licensed dataset typically includes documentation of data provenance, refresh schedule, and permitted uses.

How accurate is the B2B email data?

The EmailAddress.ai B2B database carries 98%+ verified email coverage on US contacts, based on multi-source cross-validation and catch-all domain resolution before delivery. On verified lists, bounce rates stay below 3%. The 99.3% enrichment accuracy figure refers to the cross-source validation score applied across all fields, not email alone.

What does 99.3% enrichment accuracy mean?

It means that when a record's name, title, company, and contact fields are validated across multiple independent data sources, 99.3% of the cross-source signals agree. It is a data quality score, not a claim that every email will deliver. Email deliverability depends on both data accuracy and the recipient's mail infrastructure.

Can I filter B2B data by industry, company size, or geography?

Yes. Records can be filtered by NAIC industry code (80+ classifications), company size by employee count, company revenue range, geography at state or zip code level, and job title by function or seniority. Filtering parameters are confirmed before delivery, and sample data is provided within two business days.

How often is the B2B data refreshed?

The full database is refreshed quarterly. US and UK records are re-verified for email deliverability at each cycle. Teams on recurring delivery agreements receive a timestamped file at each quarterly refresh.

Do you have B2B contact data outside the US?

Yes. The database includes 5.35M verified contacts in the UK and Ireland, and 1.61M Canadian contacts with firmographic data. Professional email is included for US and UK records. Additional international coverage is available through the global data expansion in progress — see the global coverage page for details.
