The landscape of digital marketing within the European Union is undergoing a significant transformation, with recent guidance from French and Italian data protection authorities clarifying that email tracking pixels, much like website cookies, generally require explicit user consent under existing ePrivacy and GDPR rules. Issued in March and April 2026 by France’s Commission Nationale de l’Informatique et des Libertés (CNIL) and Italy’s Garante per la Protezione dei Dati Personali (the Garante), these pronouncements are not new laws but rather authoritative interpretations of long-standing directives, compelling businesses to re-evaluate their email marketing strategies and data collection practices across the bloc. This marks a pivotal moment, pushing email tracking into an era of heightened transparency and user control, aligning it more closely with the stringent standards already applied to web tracking for several years.
Background: The Foundation of EU Data Privacy
The regulatory framework underpinning these clarifications rests primarily on two pillars: the ePrivacy Directive (2002/58/EC), often referred to as the "Cookie Law," and the General Data Protection Regulation (GDPR) (EU 2016/679). The ePrivacy Directive specifically addresses the processing of personal data and the protection of privacy in the electronic communications sector. It mandates that accessing information stored on a user’s terminal equipment (such as a computer or mobile device) requires the user’s prior consent, unless it is strictly necessary for the provision of a service explicitly requested by the user or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. This is the very principle that led to the ubiquitous cookie consent banners on websites across the EU.
The GDPR, which came into effect in May 2018, significantly strengthened data protection rights for individuals and imposed strict obligations on organizations processing personal data. It introduced concepts like explicit consent, the right to be forgotten, and data portability, alongside substantial penalties for non-compliance. While ePrivacy deals with the access to information on a device, GDPR governs the processing of any personal data that might be collected through that access. Email tracking pixels, by their nature, often access a user’s device (to determine if an email has been opened, for instance) and then process personal data (linking an open event to a specific email address and user ID). Therefore, both regulations are directly applicable.
The timing of this guidance reflects a broader trend of increased scrutiny by data protection authorities (DPAs) across Europe. As digital marketing techniques become more sophisticated, regulators are ensuring that foundational privacy principles keep pace, closing what some might view as loopholes or ambiguities in existing legislation. The European Data Protection Board (EDPB), which comprises representatives from national DPAs, plays a crucial role in ensuring consistent application of GDPR and ePrivacy across member states, often issuing guidelines that national authorities then interpret and enforce. This harmonisation effort suggests that the French and Italian guidance could serve as a blueprint for similar interpretations from other EU countries.
The Core of the Guidance: Consent is Key
Both CNIL and the Garante concur on a fundamental premise: tracking pixels embedded in emails access information from a user’s device, bringing this activity squarely under the ePrivacy Directive. Consequently, explicit consent is generally required unless a specific and narrowly defined exemption applies. This moves email tracking away from an implied consent model, or reliance on legitimate interest, towards a stricter, opt-in standard for many common tracking practices.
Divergence in Detail: France’s Flexibility vs. Italy’s Strictness
While sharing the core principle, the French and Italian authorities offer slightly different interpretations, particularly concerning the so-called "deliverability exemption." This term, while not a formal legal construct, refers to the acknowledged need for email senders to monitor basic email delivery for technical and security purposes.
France (CNIL): Narrow, Conditional Flexibility
CNIL’s guidance allows for individual-level open tracking without explicit consent, but only under very strict conditions and for tightly scoped deliverability purposes. These conditions include:
- Purpose Limitation: Data collected must be exclusively used to detect non-delivery or technical issues, identify inactive recipients to prevent email addresses from becoming spam traps, or to manage anti-abuse systems. It explicitly cannot be repurposed for marketing analytics, personalization, or commercial profiling.
- Data Minimisation: Only the absolute minimum data necessary for these purposes should be collected, such as the last open date. Comprehensive engagement histories or detailed user behaviour tracking are generally excluded.
- Contextual Application: This exemption applies only to emails that the recipient explicitly requested or consented to receive, meaning it cannot be used for unsolicited communications.
- No Repurposing: The data cannot be linked with other data sets for broader analytical or marketing objectives.
Crucially, CNIL mandates that if these strict conditions are not met – for example, if open data is used for segmentation, A/B testing, or personalized content delivery – then explicit consent is required.
Italy (Garante): Stricter Than Most Realize
The Garante adopts a significantly more stringent position. Its guidance generally limits consent-free exemptions for email tracking to aggregate, anonymized statistics. This means that, typically, only a single, shared pixel per campaign would be permissible without consent, and any collected data, including IP addresses and technical identifiers, must be anonymized to prevent individual identification. Per-recipient tracking, which is standard in most email service provider (ESP) models, would almost always require explicit consent in Italy, with very few exceptions beyond specific security and authentication use cases directly tied to the service provision.
This divergence presents a considerable challenge for businesses operating across the EU. Most standard ESP tracking architectures are designed to generate per-recipient open events by default. While this might, with appropriate data minimization and purpose limitation, satisfy CNIL’s deliverability exemption, it generally falls short of the Garante’s requirements without substantial architectural changes. If a business’s analytics, automation, or personalization efforts depend on individual engagement signals, they are firmly in consent territory for recipients in Italy.
Key Implications for Businesses
The guidance highlights several critical points that demand immediate attention from email marketers and data controllers:
-
Consent to Send Email is Not Consent to Track It: This is perhaps the most significant revelation for many. Even if a business has a valid legal basis (e.g., explicit consent, legitimate interest, contractual necessity) to send marketing, transactional, or service emails, this does not automatically extend to permission to track opens within those emails. The consent requirement applies specifically to the tracking pixel accessing information on the user’s device, irrespective of the message’s content or purpose. CNIL is explicit that tracking consent can be required even when the email itself does not require consent, meaning transactional emails are not exempt from this pixel-specific consent requirement. In some cases, these consents might be bundled if clearly and transparently presented to the user, but the default assumption that "they signed up, so we can track them" is no longer valid.
-
A Contract Alone Does Not Prove Consent: For businesses whose email lists include rented contacts, partner-sourced addresses, affiliate leads, or data imported from third parties, the burden of proof for consent is substantial. CNIL requires demonstrable evidence for each individual recipient: who consented, when, and under what specific conditions. A contractual clause stating that a partner collected consent on your behalf is insufficient on its own. Businesses must be able to produce specific evidence of informed consent from each individual. This necessitates rigorous vendor management and due diligence to ensure third-party data sources meet these stringent EU privacy standards, a critical conversation point for legal and compliance teams.
-
The Infrastructure Problem: Dynamic Consent Checking: Both regulators emphasize that consent withdrawal must be easy and effective immediately, even for emails already delivered to an inbox. This means that if a user withdraws consent today, and then opens an email sent three months ago, that open event should not be logged as an identifiable action. This requires a sophisticated, consent-aware pixel infrastructure where the pixel endpoint dynamically checks the user’s current consent status at the moment of each open. The image might still load (to avoid breaking the email display), but the tracking logic must adapt. Most existing email systems, including those of major ESPs, were not initially designed with this dynamic, real-time consent checking capability. Bridging this architectural gap represents a significant technical undertaking for the industry.
-
The Non-Human Interaction Problem: The utility of "open" data has been eroding for years due to technological changes like Apple Mail Privacy Protection (MPP), which pre-fetches images, generating false opens. Security gateways and spam filters also automatically scan messages, triggering pixel loads before any human interaction. Regulators, particularly CNIL, suggest that opens can be used without consent to identify inactive recipients (for deliverability purposes). However, if these "opens" are increasingly non-human, the data becomes unreliable for its intended purpose. Furthermore, the techniques required to filter out non-human activity (e.g., advanced bot detection) may themselves involve individual-level data processing that requires consent. This creates a challenging paradox: businesses need cleaner data to comply, but cleaning the data might require the very consent they are trying to manage. This unresolved tension remains a key area for future regulatory clarification.
Impact on Analytics and Marketing Strategies
The cumulative effect of these changes means that traditional email analytics, heavily reliant on open rates, will become less reliable and potentially misleading. If open tracking becomes consent-gated, analytics will only reflect data from a self-selecting, likely smaller, and highly engaged segment of subscribers who opted into tracking. This biased sample, further polluted by machine-generated opens, renders open rates statistically unreliable for drawing conclusions about a broader audience.
This degradation of open data directly impacts:
- Automation Triggers: Flows based on "opened email" will need re-evaluation.
- Re-engagement Campaigns: Identifying inactive users via opens becomes problematic.
- Subject Line Testing & Personalization: A/B tests based on open rates will yield skewed results.
- Segmentation & Engagement Scoring: Many existing models will lose their foundational data.
While these functions won’t cease overnight, their effectiveness will diminish significantly. The programs least affected will be those already pivoting towards more intentional engagement signals: clicks, conversions, replies, and other explicit user actions. This guidance accelerates an existing trend, confirming that passive "opens" are increasingly becoming both noisy and selectively reported.
Broader EU and Global Implications
The French and Italian guidance, while specific to their jurisdictions, is likely a harbinger for the broader EU. Both DPAs draw on the same foundational EDPB framework, making it a reasonable prediction that other EU member states will issue similar, potentially harmonized, interpretations over time. For many international senders, aligning with the stricter Italian standard across all EU sending might be the cleanest path to reduce fragmentation, mitigate risk, and future-proof compliance efforts.
Beyond the EU, the trend towards greater transparency and consent in digital tracking is global. The UK’s Privacy and Electronic Communications Regulations (PECR) and guidance from the Information Commissioner’s Office (ICO) impose comparable requirements for cookie-like technologies, including tracking pixels. In North America, Canada’s Anti-Spam Legislation (CASL) includes stringent consent requirements, and emerging state privacy laws in the United States (e.g., CCPA/CPRA in California, Virginia CDPA, Colorado CPA) are pushing towards similar principles of consumer control over personal data. This global movement underscores that explicit, demonstrable consent is becoming the gold standard for data collection.
The Role of Email Service Providers (ESPs)
ESPs like Sinch’s Mailgun and Mailjet operate as data processors within the CNIL framework, meaning they process data on behalf of their clients. The sender, as the data controller, retains the primary responsibility for collecting, storing, and demonstrating recipient consent. ESPs cannot inherently know whether a recipient consented to tracking; this signal must originate from the data controller.
However, ESPs have a crucial role in providing the tools and architecture to facilitate compliance. This includes offering flexible controls at the account, subaccount, and API key levels, clearly documenting how their systems function, and evolving their platforms to support consent-aware tracking behaviors. The industry anticipates a need for ESPs to develop features that allow clients to pass consent status information, enabling dynamic pixel behavior. This collaborative effort between data controllers and processors will be essential for navigating the new regulatory landscape.
Immediate Actions for Businesses
Given the impending nature of these shifts, businesses are advised to take proactive steps:
- Audit Open Data Usage: Map precisely where open data feeds into internal systems, including automation triggers, analytics dashboards, segmentation logic, personalization efforts, and deliverability decisions. Understand the potential degradation of these functions if open signals become consent-gated or noisier.
- Review Consent Flows and Privacy Documentation: Examine sign-up forms, privacy policies, and terms of service. Ensure that pixel tracking is explicitly mentioned, clearly described, and that consent for tracking is collected at the point of email address capture where possible, separate from general email subscription consent.
- Scrutinize List Origins: For any email addresses not obtained through direct, first-party sign-up forms (e.g., rented lists, co-registered data, partner-provided leads), verify the ability to prove individual, informed consent. A contract alone is insufficient. Ensure compliance with ESPs’ acceptable use policies, which often prohibit certain types of third-party lists.
- Identify EU Exposure: Determine the concentration of email recipients in France and Italy. These markets represent the immediate priority for compliance adjustments.
- Strategic Decision on Tracking: Avoid reactive disabling of all open tracking without a full understanding of its implications. Instead, conduct a comprehensive assessment of how the recent guidance impacts your specific use of information, then make informed decisions about enabling or disabling tracking, or implementing consent-gated solutions.
The Bigger Picture: A Shift Towards Intentional Engagement
This regulatory guidance is not an outright prohibition on email tracking but rather a powerful signal that email is entering the same privacy-first paradigm that web tracking has inhabited for years. The future demands clearer purpose, enhanced transparency, and greater user control.
The silver lining is that email marketers have the opportunity to prepare. Unlike the initial scramble to adapt to cookie consent banners on websites, the email industry can anticipate and proactively build solutions. This shift also aligns with existing market trends; open rates were already becoming less reliable due to technological interventions like Apple MPP and the proliferation of security scanners. The guidance merely formalizes this reality.
The future of email engagement lies in intentional signals: clicks, conversions, replies, and other explicit user actions that genuinely reflect interest and engagement. While there are no widespread enforcement campaigns today, the trajectory is unmistakable. The gap between current email tracking practices and regulatory expectations is real, and closing it will require time, cross-functional coordination, and significant architectural rethinking. However, being able to see this coming puts businesses in a far better position than reacting after the fact.
