Legal Compliance··6 min read
Key takeaways
Yes, you can prospect in B2B while being GDPR compliant. The key is using publicly available business data and relying on legitimate interest as your legal basis
Non-compliance fines can reach 20 million euros or 4% of global turnover, but most B2B penalties are for avoidable bad practices
Platforms like Vonsel work exclusively with verified public data from accessible sources, which keeps compliance simple
Yes, a B2B sales team can prospect under GDPR without asking for consent first, provided it relies on legitimate interest (Article 6.1.f), contacts people through professional details, tells them where the data came from and honours every opt-out. Fines reach 20 million euros or 4% of worldwide turnover, so keep a written record.
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 allows prospecting as long as you have a valid legal basis for processing data and respect the data subject's rights. In B2B, the two most common bases are consent and legitimate interest.
When you work with publicly available business data (phone numbers, corporate emails, addresses published on websites or registries), compliance is much simpler, because the businesses published that data voluntarily.

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 matters 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
Search Maps, collect published website contacts and organise your prospects in the CRM. Free extraction covers 200 businesses a month; AI and export depend on your plan.
Work with data that businesses publish voluntarily: corporate websites, business registries, Google Maps. Platforms like Vonsel collect exclusively from verified public sources.
2
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.
GDPR is not an obstacle for B2B sales: it is a competitive advantage when you do it right
In summary
GDPR allows B2B prospecting with publicly available business data as long as you rely on legitimate interest and offer opt-out
Vonsel works exclusively with verified public data from accessible sources (Google Maps, corporate websites, registries), so compliance stays easy

Find local businesses with Vonsel
Search Google Maps and press Start. Vonsel gathers the business results as you explore the map, going beyond the pins you can see at a glance. Pause, continue and save your search when you are ready. Google Maps does not provide business emails. Vonsel visits the available business websites to find published emails, additional phone numbers and links to up to 118 supported social networks and other platforms. What it finds depends on what each website publishes. Keep businesses on a map, organise them by stage, edit their details and use a Kanban board, calendar, notes, actions, tags and custom fields. Basic holds 400, Pro 2,000 and Scale 10,000.
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.
Does GDPR apply if my company is outside the EU?
Yes, if you process personal data of people in the EU. The regulation applies wherever your company is based, so a team in the US or Brazil that prospects European businesses and handles the names or work emails of individuals has to follow it. Where you are located changes nothing about the duties to document your legal basis and respect opt-outs.
Can someone object to my B2B sales emails after I contact them?
Yes. Article 21 gives people the right to object to the use of their data for direct marketing at any time, and the UK regulator describes that right as absolute whatever lawful basis you rely on. Stop contacting the person as soon as they object, remove them from your lists, and keep a suppression record so they are not added again.
What is a legitimate interest assessment and do I need one?
A legitimate interest assessment (LIA) is a short internal document explaining why you contact a certain group of businesses and why that is reasonable. You do not file it with anyone, but you should be able to hand it to a data protection authority if it asks. Review it whenever your targeting or data sources change.
Should a B2B team choose consent or legitimate interest?
Most B2B teams rely on legitimate interest under Article 6.1.f, because asking for consent before every first contact slows outreach down. Consent suits newsletters and B2C marketing, where people sign up on their own. Legitimate interest works when the data is professional, the commercial purpose is genuine and the recipient can opt out easily. Whichever basis you pick, write it down.
What should I tell a prospect about where I got their data?
Name the public source the data came from, for example their website, a business registry or their Google Maps listing, and say why you are contacting them. GDPR's transparency requirement means the recipient should never have to guess. Keep a note of the source for each contact so you can answer quickly if they ask later. Rules on email marketing also differ by country, so check yours or ask a lawyer.
