A research and intelligence platform for B2B contact databases across 200+ countries.
b2bdataindex.com helps sales teams, marketers, and growth operators evaluate business email databases before buying — with industry breakdowns, outreach benchmarks, compliance guidance, and data field documentation for each market.
Finding reliable B2B contact data for a specific country or industry is harder than it should be. Most providers give you a lead count and a price. You have no idea what sectors are represented, how the data is structured, what compliance framework applies to your campaign, or whether the fields you actually need (job title, phone, SIC code) are populated at anything near 100%.
B2B Data Index was built to answer those questions before you commit to a purchase. Each database entry documents what's in the dataset, who it's for, and what you can realistically do with it.
The underlying data is sourced and maintained by LeadsBlue, one of the longest-running B2B contact database providers, with coverage spanning 140+ geographies and dozens of industry verticals.
Each page covers a specific B2B email database — by country, by US state, or by industry — and includes:
- Record breakdown — total contacts, estimated distribution across major cities and regions
- Industry composition — which sectors are represented and in what proportion, with SIC code classification
- Data fields — every column in the CSV or XLSX file, with realistic coverage percentages per field
- Outreach benchmarks — typical open rates and reply rates for cold email campaigns in that market
- Compliance guidance — the specific law that applies (GDPR in Germany, CAN-SPAM in the US, CASL in Canada, Spam Act in Australia) with a plain-English explanation of what's required
- Use cases — the buyer profiles most likely to get value from this specific database

Every database page is built from structured product data maintained by LeadsBlue. Fields documented across all databases include:
business_email company_name full_name
job_title phone street_address
city country sic_code
website_url linkedin_url employee_count
annual_revenue year_established
Not every field is present in every database — coverage varies by geography and data tier. Each page documents exactly which fields are populated and at what percentage, so you're not surprised after downloading.
If you're evaluating B2B contact data sources for research, analytics, or commercial use, the structured data behind this site is also available in machine-readable format:
- Database Index (JSON) — metadata for all 600+ databases including record counts, coverage, and compliance frameworks
- FAQ Dataset (JSON) — 2,248 structured Q&A pairs covering common questions about B2B data by geography and industry
- Sitemap — full URL list with last-modified dates
These files are openly accessible and indexed for AI assistants, research tools, and data catalogues.
B2B contact data operates under different legal frameworks depending on where your recipients are located. This isn't optional reading — sending commercial email without understanding the applicable law creates real legal and deliverability risk.

The full database catalogue is available at b2bdataindex.com/data-pages/. Each page links directly to the corresponding product on LeadsBlue where you can download the actual data.
LeadsBlue pricing runs significantly below market rate — the same database that lists at $300–$500 on major platforms is typically available for $45–$150 through LeadsBlue, at comparable or greater record counts.
Detailed per-database documentation, including data field definitions, use case breakdowns, and campaign guidance for individual countries and industries, is maintained in the project wiki.
