July 15, 2026 — Businesses engaging in email communications within the European Union, or targeting EU-based contacts, face significant changes as new recommendations regarding the tracking of email open rates come into effect. Following joint public consultations, France’s data protection authority, CNIL (Commission Nationale de l’Informatique et des Libertés), and its Italian counterpart, Garante per la protezione dei dati personali (Garante), published final recommendations in April 2026, clarifying that explicit prior approval from recipients is now required to track when they open emails. This move, which effectively extends existing data protection principles, aims to enhance individual privacy in the digital realm and prevent costly fines for non-compliance.
The new guidelines do not introduce entirely novel legislation but rather specify the application of existing regulatory frameworks, primarily the ePrivacy Directive, alongside the General Data Protection Regulation (GDPR) requirements concerning the processing of personal data. The core directive is clear: in addition to the traditional opt-in checkbox for receiving marketing communications, an entirely separate and distinct opt-in checkbox is now necessary for recipients to consent to their email behavior, specifically open rates, being tracked. This dual-consent mechanism underscores a growing regulatory emphasis on granular control over personal data and digital interactions.
The Evolution of Digital Privacy: A Regulatory Chronology
The current recommendations from CNIL and Garante represent the latest development in a long-standing European commitment to digital privacy. This commitment is primarily anchored by two foundational pieces of legislation: the ePrivacy Directive (Directive 2002/58/EC, often called the "Cookie Law") and the General Data Protection Regulation (Regulation (EU) 2016/679, or GDPR).
The ePrivacy Directive, enacted in 2002 and subsequently amended in 2009, specifically addresses the confidentiality of electronic communications and the protection of users’ privacy. Article 5(3) of this directive mandates that the storage of information, or the gaining of access to information already stored, in the terminal equipment of a subscriber or user is only allowed on condition that the subscriber or user concerned has given his or her consent, having been provided with clear and comprehensive information. This directive was initially interpreted primarily for cookies but has increasingly been applied to other online tracking technologies.
Building upon this foundation, the GDPR, which became enforceable in May 2018, significantly strengthened data protection rights across the EU. It introduced stringent requirements for how personal data is collected, processed, stored, and protected, emphasizing principles like lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity, confidentiality, and accountability. Critically, GDPR defines "personal data" broadly, including identifiers like IP addresses and unique tracking codes, which are often collected by email tracking pixels. The GDPR’s definition of valid consent—requiring it to be freely given, specific, informed, and unambiguous—is central to the new email tracking recommendations.
The European Data Protection Board (EDPB), composed of representatives from national data protection authorities like CNIL and Garante, plays a crucial role in ensuring consistent application of GDPR and the ePrivacy Directive across the EU. Their "Guidelines 2/2023 on the technical scope of Article 5(3) of the ePrivacy Directive" were particularly influential. These guidelines clarified that any technology that accesses or stores information on a user’s device, even temporarily and indirectly (such as a tracking pixel loading from a remote server, thereby revealing an email has been opened), generally falls under the consent requirement of the ePrivacy Directive. This broad interpretation paved the way for the specific recommendations now issued by France and Italy concerning email open tracking.
Both CNIL and Garante are independent agencies with significant regulatory powers. They are not only enforcers of the GDPR, capable of issuing substantial fines for non-compliance, but also producers of authoritative recommendations that interpret how European laws should be applied in specific national contexts, reflecting the evolving landscape of digital technologies and user privacy concerns. Their joint action underscores a harmonized approach to a shared challenge.
Understanding Email Tracking Pixels and Their Privacy Implications
At the heart of this regulatory shift are tracking pixels. These are minuscule (typically 1×1 pixel), often invisible images embedded within emails. When an email containing such a pixel is opened, the recipient’s email client or browser requests the image from a remote server. This request transmits information such as the recipient’s IP address, the time the email was opened, the device used, and sometimes even the geographical location. A unique identifier embedded in the image’s filename allows email service providers and marketers to link this open event back to a specific individual recipient.
The use of tracking pixels has become ubiquitous in email marketing, driven by their utility in:
- Measuring audience engagement: Determining open rates, a foundational metric for campaign performance.
- Personalizing communications: Understanding recipient behavior to tailor future content.
- Optimizing send times: Identifying when recipients are most likely to engage.
- Checking deliverability: Confirming that emails are reaching inboxes and being seen.
However, despite their practical benefits, tracking pixels have increasingly raised significant privacy concerns. Email is widely considered a private and personal communication channel. The invisible nature of these trackers means recipients are often unaware that their interactions are being monitored. This lack of transparency and control over personal data has led to a rising number of complaints received by data protection authorities, reinforcing the regulators’ view that such tracking constitutes a significant privacy intrusion without explicit consent. The ability to build detailed profiles of individuals based on their email opening habits, potentially correlating with other online activities, further amplifies these concerns, linking them directly to the GDPR’s principles of data minimization and transparency.
The New Recommendation: Explicit Consent for Tracking
The central tenet of the CNIL and Garante recommendations is the requirement for prior, explicit consent for email open tracking. This means that merely obtaining consent to send marketing emails is no longer sufficient if tracking pixels are used. Marketers must now implement an additional, distinct opt-in mechanism specifically for tracking email behavior.
Key requirements for compliant consent include:
- Freely Given: Individuals must have a genuine choice, without coercion or negative consequences for refusal.
- Specific: Consent must relate to a clearly defined purpose – in this case, tracking email open rates.
- Informed: Recipients must be fully aware of what data is being collected, how it will be used, and who will be processing it. This information should be easily accessible, for instance, through a clear privacy policy link.
- Unambiguous: Consent must be indicated by a clear affirmative action, such as ticking a separate, unticked checkbox. Pre-ticked boxes are not valid.
- Easy to Withdraw: Individuals must be able to withdraw their consent at any time, with the same ease as they gave it.
These rules effectively extend the stringent GDPR consent standards directly to the practice of email open tracking. The recommendations apply universally to any organization, whether public or private, that utilizes tracking pixels in emails, as well as the technical service providers they rely upon.
Exemptions and the Challenge of Transactional Emails
While the new consent requirements are broad, there are limited exemptions where individual tracking consent may not be strictly necessary. These exemptions apply when the information accessed or stored is strictly necessary for:
- Providing a service explicitly requested by the user: For example, tracking to ensure the proper functioning of a secure communication service.
- Maintaining the security of the service: Detecting fraud or ensuring the integrity of the communication system.
- Generating aggregate statistical data: Provided this data cannot be linked back to individual recipients and is used solely for the technical performance or security of the email service.
Crucially, organizations claiming an exemption must be able to demonstrate that the tracking is strictly limited to these specific, necessary activities and that no other personal data beyond what is essential is collected or processed. This burden of proof rests firmly with the data controller.
One particularly challenging area impacted by the recommendations is transactional emails. These are non-promotional communications triggered by a user’s specific action, such as order confirmations, password resets, shipping updates, or account notifications. While consent to receive these emails is generally implied by the user’s action (e.g., making a purchase), the consent for tracking open rates within these emails is not. This means that even for transactional messages, if an organization wishes to track individual open rates, they might still need to obtain explicit consent. This poses a significant operational challenge, as users typically expect transactional emails to be purely functional and may be less inclined to engage with additional consent prompts for such communications. Businesses must carefully evaluate their need for open rate tracking on transactional emails versus the potential friction introduced by requesting additional consent.
The Ramifications of Non-Compliance: A High-Stakes Environment
The recommendations, though fresh, are an extension of the GDPR. This means that the penalties for non-compliance are severe and substantial. Depending on the gravity and nature of the infraction, organizations could face:
- Administrative fines: Up to €10 million, or 2% of the company’s total worldwide annual turnover of the preceding financial year, whichever is higher.
- Higher-tier administrative fines: For more severe infringements, fines can reach up to €20 million, or 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher. This applies to violations of core principles like consent.
To put these figures into perspective, numerous companies, including major tech giants, have faced multi-million euro fines for GDPR violations since 2018. For instance, Amazon was fined €746 million by Luxembourg’s data protection authority in 2021, and Meta (formerly Facebook) has faced multiple significant fines from the Irish DPC. While these specific cases varied in their nature, they underscore the regulatory bodies’ willingness to levy substantial penalties for data protection breaches. Beyond financial penalties, non-compliance can lead to:
- Reputational damage: Public scrutiny and loss of customer trust can severely impact brand loyalty and market standing.
- Operational disruptions: Data protection authorities can order organizations to cease specific data processing activities, undergo audits, or implement corrective measures, all of which can be costly and disruptive.
- Legal challenges: Individuals whose privacy rights have been infringed upon may also pursue private legal claims for damages.
Industry Response and Solutions: Sinch Mailjet’s Proactive Approach
In anticipation of these evolving regulations, leading email service providers are introducing tools to help their clients navigate the new compliance landscape. Sinch Mailjet, recognizing its role as a spearhead in ensuring compliance and data privacy within the emailing industry, has been actively developing solutions.
Anonymous Tracking, already available on Starter plans and above, allows businesses to continue measuring campaign-level performance without collecting recipient-level tracking data. This means overall open and click activity can still be aggregated, providing valuable insights into campaign effectiveness without infringing on individual privacy. It’s a practical solution for those who need general performance metrics without individual behavioral profiling.
As of September 3, 2026, Email Tracking Consent has been made available on all Sinch Mailjet plans. This feature empowers contacts to independently allow or refuse individual open and click tracking, crucially, without unsubscribing from email communications altogether. Businesses can collect these preferences through integrated Mailjet Forms, a dedicated tracking-preferences link embedded in emails, or by managing preferences directly through contact profiles and list imports. This comprehensive solution provides the necessary technical infrastructure for marketers to obtain and manage explicit consent for tracking.
Furthermore, Subaccount Tracking Settings are planned for Premium plans and above. This upcoming capability will allow eligible customers, particularly larger organizations or agencies managing multiple brands or clients, to configure tracking settings independently for each subaccount. This flexibility is vital for businesses operating across diverse markets with varying compliance requirements or managing different business lines with distinct data processing needs.
It is important to note that while these features provide robust technical tools to support a privacy-first tracking strategy, the ultimate responsibility for compliance remains with the individual organization. Businesses must accurately determine which requirements apply to their specific operations, inform recipients transparently, define the precise purposes of tracking, and meticulously collect consent when required. Seeking legal counsel to ensure full adherence to GDPR and national data protection laws is strongly advised. Detailed guidance is available through Mailjet’s dedicated help pages on Email Tracking Pixels and Consent.
Shifting Paradigms: Beyond the Open Rate
The new regulations also accelerate a trend that has been underway for several years: the declining reliability of the email open rate as a primary performance metric. This shift was significantly propelled by Apple’s Mail Privacy Protection (MPP), introduced in September 2021. MPP works by pre-fetching and pre-opening emails in the background for Apple Mail users, regardless of whether the user actually views the email. This action triggers tracking pixels, making it appear as if an email has been opened, even if it hasn’t. Consequently, individual open rates for a significant segment of email recipients (Apple Mail users) became artificially inflated and largely meaningless for genuine engagement measurement.
This development, combined with the new EU consent requirements, necessitates a fundamental re-evaluation of email marketing measurement strategies. Marketers are increasingly encouraged to shift their focus to more robust and actionable metrics that genuinely reflect recipient engagement and conversion.
Key metrics to prioritize include:
- Click-Through Rate (CTR): This measures the percentage of recipients who clicked on a link within the email. A click unequivocally indicates engagement and interest in the content, making it a far more reliable indicator of a user’s intent than an open.
- Conversion Rate: This tracks how many recipients complete a desired action after clicking through from an email, such as making a purchase, filling out a form, or downloading a resource. This is the ultimate measure of an email campaign’s business impact.
- Engagement Beyond Clicks: Metrics like time spent on landing pages, subsequent website activity, and the overall journey a user takes after interacting with an email provide a richer picture of effectiveness.
- Unsubscribe Rate: While seemingly negative, a low unsubscribe rate indicates that content is relevant and valuable to the audience.
- Spam Complaint Rate: A critical indicator of email list health and content relevance.
Even in an era of less stringent regulation, an email campaign that achieved a high open rate but garnered no clicks or conversions was largely considered a failure. The true value of email marketing lies in its ability to drive meaningful engagement and ultimately convert interactions into tangible business outcomes. The current regulatory environment, while introducing new complexities, also presents an opportunity for marketers to refine their strategies, focus on quality content that genuinely resonates with recipients, and build stronger, more transparent relationships based on trust and explicit consent.
Broader Impact and Future Outlook
The new recommendations from CNIL and Garante underscore a broader, irreversible global trend towards stricter data privacy regulations. These developments are not isolated incidents but rather integral components of an evolving digital landscape where user rights and data protection are increasingly prioritized. The explicit consent requirement for email open tracking will undoubtedly impact email marketing practices, pushing businesses towards greater transparency and accountability.
For consumers, this move offers enhanced control over their personal data, aligning with the fundamental principles of privacy that the EU champions. For businesses, it necessitates a recalibration of marketing strategies, investment in compliant technologies, and a deeper understanding of legal obligations. While the immediate focus is on France and Italy, these recommendations set a precedent that could influence interpretations and enforcement actions by other EU data protection authorities. Furthermore, ongoing legislative initiatives, such as the proposed ePrivacy Regulation, which aims to replace the current ePrivacy Directive, suggest that the regulatory environment will continue to evolve, demanding continuous vigilance and adaptation from all digital communicators. The era of passive, invisible tracking is giving way to one of explicit consent and user empowerment, shaping the future of digital engagement.
