The Best B2B Data Providers for Spain and Portugal in 2026
For Spain and Portugal, Sendburg and Apollo are the self-serve options with free plans, Cognism suits enterprise calling teams, and Sales Navigator maps accounts. Spain's LSSI generally requires prior consent for commercial email, so many teams lead with LinkedIn and phone.
Madrid, Barcelona, Lisbon and Porto have become major hubs for tech, services and nearshore teams. Buyers expect Spanish or Portuguese outreach and a relationship-led approach. Here's how the tools compare.
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
