Legal Context
What is GDPR and why does it affect B2B sales?
The GDPR (General Data Protection Regulation) is the European regulation governing how companies collect, store and use personal data. It came into effect in 2018 and applies to any company processing data of individuals in the EU, regardless of where the company is based. GDPR-compliant data handling can actually improve client trust and retention, as Paddle notes in their analysis of data practices that support both compliance and retention.
For sales teams, GDPR does not prohibit prospecting. What it requires is a valid legal basis for processing data and respect for the data subject's rights. In B2B, the two most common bases are consent and legitimate interest.
The good news: when you work with publicly available business data (phone numbers, corporate emails, addresses published on websites or registries), compliance is much simpler. That data was voluntarily published by the businesses themselves.

Legal bases
Consent vs. Legitimate Interest: which to use in B2B?
GDPR establishes 6 legal bases for data processing. In B2B sales, the two relevant ones are explicit consent and legitimate interest. The difference is crucial for your prospecting strategy:
Explicit consent
You need the contact to opt in before receiving communications. Ideal for B2C and newsletters, but slows down B2B prospecting.

Legitimate interest (Art. 6.1.f)
You can contact businesses if you have a legitimate commercial interest, data is professional and you offer easy opt-out. The standard basis for B2B sales in Europe.

Legal and efficient B2B prospecting
Vonsel works only with verified public business data. Stay GDPR compliant without losing speed.
Work with data that businesses publish voluntarily: corporate websites, business registries, Google Maps. Platforms like Vonsel collect exclusively from verified public sources.

Document your legitimate interest
Write an internal document (LIA — Legitimate Interest Assessment) justifying why you contact those businesses. You don't need to submit it, but it must be ready if a data protection authority requests it. Referral programs must be designed with data privacy in mind; Tremendous addresses compliance in GDPR considerations when running referral programs.
3
Include opt-out in every communication
Every email or message must include a clear unsubscribe link. Failing to do so accounts for 68% of penalties in B2B email marketing.
4
Keep your database updated
Remove contacts who opt out. Clean your database periodically. Outdated data not only breaches regulations, it also wrecks your campaign metrics. Data privacy regulations are part of a broader shift in consumer expectations, as McKinsey explores in global trends in data privacy and regulation.
5
Respond to data subject requests
If someone requests access, rectification, or erasure, you have 30 days to respond. Having a clear process for handling deletion requests is mandatory.
72% of European B2B sales teams use legitimate interest as their legal basis for prospecting. This is not a grey area: it is the pathway designed by GDPR for commercial activity with professional data.
Can a B2B sales team use company data without prior consent?
Yes, as long as it is based on legitimate interest (Art. 6.1.f GDPR) and the data is professional or publicly accessible. The GDPR allows contacting businesses without explicit consent when there is a legitimate commercial interest and the data subject's rights are respected.
Is it legal to use business contact data published on Google Maps?
Yes. Data that businesses voluntarily publish on Google Maps, their websites or public registries is publicly accessible data. Using it for B2B prospecting is legal under GDPR, as long as you inform the recipient and respect their right to object.
What penalties can a company face for GDPR non-compliance in sales?
Penalties can reach up to 20 million euros or 4% of annual global turnover, whichever is higher. However, most B2B penalties are for mass emailing without legal basis, not for legitimate prospecting with verified public data.
