Exceptions Are Narrower Than You Might Hope

The CNIL does allow some tracking without explicit consent, but only under specific conditions. Exceptions may apply for pixels used purely for technical purposes (security, authentication) or for aggregate, non-identifiable measurements of open rates. However, identifying who individually opens emails, targeting contacts according to opening behavior, or personalizing content based on individual opening interactions all require explicit consent. However, measuring overall opening rates anonymized at the campaign level or by recipient domain does not require additional consent.

This distinction matters for deliverability teams. You cannot use individual open data to identify bouncing addresses or inactive segments without consent, even for operational purposes.

B2B Is the Biggest Wild Card

The B2B sector will likely be the most affected, as it will now fall under the consent requirement, whereas commercial B2B emails still generally operate under an opt-out regime. Many B2B marketers have built workflows around open tracking without explicit consent, relying on soft opt-in rules for business email. That protection no longer applies to tracking pixels under the CNIL's framework.

Compliance Enforcement Timeline and Practical Steps

The CNIL will likely show leniency during the initial enforcement period, issuing reminders before fines. But organizations effectively have until January 2026 to achieve compliance. After that, enforcement actions become significantly more likely. Since that date has now passed, compliance is no longer optional.

The CNIL emphasized at its EMDay 2025 conference that organizations should not await final recommendations to comply with these requirements. The legal obligation to obtain consent for email tracking has existed since the GDPR's implementation in 2018.

What Marketers and Growth Teams Should Do Now

Start by auditing which data you're actually tracking and which marketing decisions depend on it. Organizations must demonstrate user consent at any time during regulatory audits, maintaining detailed records of when consent was obtained, what specific tracking was consented to, and how the consent mechanism was presented.

Update your signup flows to collect separate consent for tracking. Redesign automation workflows that rely on individual open data to either work with consent-granted segments only or pivot to anonymized aggregate metrics. For existing contact databases without documented tracking consent, you have two options: stop tracking these contacts or discontinue the practice entirely unless you can prove consent was collected.

The regulatory terrain is shifting across the EU, and France's CNIL is setting the pace. What was common practice for the past five years is now compliance liability. Organizations that move early to separate consent mechanisms and consent-aware tracking systems will have time to adjust workflows and messaging before enforcement intensifies.
