Digital marketing traditionally relied on massive data collection to target customers precisely. GDPR has fundamentally changed this dynamic by imposing strict rules on consent and personal data use. Today, marketing teams must navigate between two often antagonistic imperatives: maximising campaign effectiveness while respecting increasingly demanding regulation. A 2025 Forrester study reveals that 52% of marketing managers report that GDPR compliance negatively impacts results, while 38% feel they lack the tools to reconcile compliance and performance.

Managing cookies has become the main battleground for compliant digital marketing. Before GDPR, companies deployed tracking cookies without requesting explicit permission. Today, they must obtain prior, granular and revocable consent for each cookie category (analytics, marketing, social networks). CNIL intensified penalties for non-compliance: Google received a 90 million euro fine in 2021 for non-consented cookies, and Meta was sanctioned at 415 million euros in 2022. Beyond fines, trust is at stake: cookie rejection rates have increased significantly, particularly in France, with refusals reaching 70% to 80% on some sites.

Third-party data and reducing scope

With weakening third-party tracking (Apple limited cross-site tracking, Google is phasing out third-party cookies), marketing teams must rethink strategy. Many turn to first-party data: voluntarily collected emails, locally stored profile data, subscriber lists. Yet even this approach carries GDPR risks. A distribution list built without explicit consent and retained beyond a reasonable period exposes the company to fines. Meanwhile, the right to be forgotten requires companies to delete data on request within 30 days, creating operational challenges for organisations with complex data pipelines.

Toward pragmatic and strategic compliance

Forward-thinking organisations adopt a hybrid approach. They collect essential data with explicit consent and exploit it to create lasting value. They invest in compliant marketing automation technologies, implement reliable Consent Management Platforms (CMPs) and train teams. Some industry players, like Segment and Tealium, offer solutions facilitating large-scale consent management. Finally, increased transparency with customers about data use can paradoxically improve compliance and trust. Organisations clearly explaining how and why they use data typically see higher consent rates and better customer loyalty.
