The Best B2B Data Providers for the Netherlands and Belgium in 2026
Benelux is well covered by most tools, so choose on accuracy, price and phones: Cognism for enterprise calling, Sendburg and Apollo for self-serve teams with free plans, and Sales Navigator for mapping accounts.
The Netherlands and Belgium are compact, international, English-friendly B2B markets with strong logistics, tech, finance and agri-food sectors - a natural first European market for many teams. Here's how the tools compare for Amsterdam, Rotterdam, Utrecht, Eindhoven, Brussels and Antwerp.
Disclosure: Sendburg is our product. We have tried to be fair - where another tool is the better fit, we say so. Prices are from each vendor's public pricing page or widely reported figures as of November 3, 2026; they change often, so check before you buy.
How we compared
- Coverage of the region's companies and decision-makers (we tested searches in the main business cities)
- Email accuracy: is there a verified-email filter, and what happens when an email bounces
- Price for a small team, and whether there is a usable free plan
- Filters that matter for local prospecting (city, industry, title, company size)
- Phone numbers and how much they cost
- Data-protection posture for the region's laws

Benelux-specific tips
- Formats: from our study of verified Dutch work emails - Netherlands: 47.6% first.last@, 7.1% flast@, 20.9% first-name-only.
- English works for most Dutch buyers; in Belgium, match the language region (Dutch in Flanders, French in Wallonia and much of Brussels).
- Rules for marketing email differ between individuals and companies under each country's telecom law - check them before large email campaigns.
- Eindhoven, Rotterdam and Antwerp have very different industry mixes from Amsterdam and Brussels - filter by city.
