The terms “email” and “courriel” refer to the same technical object: a message transmitted electronically via the SMTP protocol. However, the French language has produced two distinct words, influenced by institutional logics and geographical usages that do not always overlap. The French legal framework adds an additional layer, as the law refers to neither email nor courriel, but rather to “courrier électronique”.
Legal status of electronic mail in France
Before questioning the correct term, it is essential to understand that French law has addressed the issue in its own way. The LCEN (Law for Confidence in the Digital Economy) has technically defined “courrier électronique” and linked it, under certain conditions, to the regime of private correspondence provided by the Postal and Electronic Communications Code.

This qualification is not trivial. A professional email sent from a corporate messaging system does not automatically benefit from the protection of private correspondence. The Council of State has also produced case law on the use of electronic mail by civil servants, distinguishing between personal use and service use.
To delve deeper into the difference between email and courriel from a linguistic perspective, it is first necessary to recognize that the term adopted by the French administration is neither one nor the other, but indeed “courrier électronique”.

Since April 9, 2024, law n°2024-322 has reinforced this trend by allowing property managers to send general assembly notices, minutes, and formal notices electronically without prior consent from co-owners. Thus, courriel becomes a functional equivalent of postal mail in this sector.
Email, e-mail, courriel: what each spelling reveals
The word “email” (without a hyphen) has become established in everyday Francophone usage through direct borrowing from English. The spelling “e-mail,” with a hyphen, remains recommended by several English dictionaries and corresponds to the historical form (abbreviation of “electronic mail”).
“Courriel” was coined in Quebec in the 1990s, by contracting “courrier électronique”. The Office québécois de la langue française was the first to adopt it. In France, the General Commission for Terminology and Neology recommended it in the Official Journal in 2003 as the official French equivalent of “e-mail”.
Three words, one technical reality
From a protocol standpoint, there is no difference. A message sent from Gmail, Outlook, or ProtonMail passes through the same SMTP servers, whether it is called email, e-mail, or courriel. The distinction is purely lexical and cultural.
The available data do not allow for precise quantification of the usage distribution among the three forms in Francophone texts. However, some trends emerge:
- “Email” overwhelmingly dominates in everyday language, marketing, and corporate communication in France.
- “Courriel” remains the norm in Quebec and in French administrative texts, particularly publications in the Official Journal.
- “E-mail” (with a hyphen) mainly appears in technical contexts or documents modeled on formal English.
Probative value of courriel compared to paper registered mail
A rarely addressed angle concerns the legal strength of a courriel compared to that of postal mail. The qualified electronic registered letter (LRE), recognized in French law since January 1, 2019, under the European eIDAS regulation, has the same legal value as a paper registered letter with acknowledgment of receipt.
This equivalence is based on Article L.100 of the Postal and Electronic Communications Code. It requires the use of a qualified trusted service provider, which excludes sending a simple courriel from a standard messaging system.
A simple email does not constitute absolute proof
An ordinary courriel can serve as the beginning of written proof, but its probative value is lower than that of a signed document. Docaposte and other operators offer qualified LRE services specifically to bridge this gap. The choice of word (email or courriel) has no impact on this value: only the technical certification mechanism matters.
Data protection and tracking pixels in emails
The CNIL has published specific recommendations regarding tracking pixels embedded in commercial emails. These pixels, invisible to the recipient, allow the sender to know if a message has been opened, at what time, and from which device.
This practice raises a compliance issue with the GDPR. The CNIL considers that the insertion of a tracking pixel requires the recipient’s consent, unless the sender can demonstrate a proportionate legitimate interest. The framework for commercial email prospecting is undergoing a gradual tightening.
Whether we talk about email or courriel, the obligations remain the same. The term used in the general conditions or consent forms does not affect the applicable legal regime. Field feedback varies on this point: some companies still believe that an “information courriel” is exempt from commercial prospecting rules, which is inaccurate as soon as the message contains a promotional dimension.
- Prior consent (opt-in) remains the rule for B2C prospecting by email.
- In B2B, opt-out is tolerated under strict conditions, but the tracking pixel poses a distinct issue.
- The carbon footprint of an email, often cited in awareness campaigns, mainly depends on the size of attachments and server storage, not on the number of messages sent.
The debate between “email” and “courriel” is primarily a matter of language register and context of use. In an administrative or legal text, “courriel” or “courrier électronique” is required. In a typical professional exchange, “email” raises no eyebrows. The only mistake would be to believe that the choice of word alters the legal or technical scope of the message sent.
