A message addressed to a professional is not automatically relevant because it is sent to a work address. The CNIL distinguishes between prospecting towards professionals and reminds that the purpose of the solicitation must be related to the profession of the person approached. For a sales team, this means being able to explain why a function was selected, providing information on the use of the address and offering a simple way to stop receiving messages. Editorial quality therefore begins before writing, when the segment and the source are defined.
French framework for international readers
CNIL is the French data protection authority. Its guidance applies the European data-protection framework in the French context and should be cited by its official acronym, not renamed as a commercial-email regulator. For an international campaign, this article provides the French operating baseline: professional relevance, transparent information and an effective way to object. It does not replace a jurisdiction-by-jurisdiction review of electronic-marketing rules. Keep the legal basis, source context and suppression evidence distinct so that a campaign can be narrowed without erasing the audit trail.
Read the visual “Proof chain of a B2B email”
A checked job function leads to the targeting reason, source and clearly identified message. The final card is the synchronised opt-out. Read together, these cards form the evidence chain that a B2B email process must preserve before sending and when a recipient objects.
Alerts specific to relevance and prospecting
- segment only by seniority or approximate title
- hide unsubscribe in an image
- reimport an opted-out contact from another file
- interpret silence as agreement
Limits of interpretation for B2B emails
A published role does not prove that the person decides alone, has a budget or wishes to be contacted. Legitimate interest is not a general authorization to send any message to any professional. A generic address does not exempt you from identifying the sender or complying with a cessation request. Finally, an absence of click or response does not constitute consent or confirmation of relevance.
Official reference for B2B email
The CNIL indicates that prospecting by email towards professionals can be based on legitimate interest, subject in particular to informing the person, allowing them to object simply and free of charge and maintaining a link between the solicitation and their profession. It distinguishes generic professional addresses, which correspond to contact details of legal entities, from addresses attached to a person. Each message must identify the sender and offer a way to stop the solicitations. These principles need to be translated into fields and controls, not just a boilerplate phrase.
Instructions for using the “Preview of a B2B campaign” tool
It checks the functional relevance, information and opt-out mechanism before sending. The entries are: offer, targeted function, source address, collection date, information text, opt-out channel. The expected output is a green light, hold or a documented refusal. The safeguards are explicit: no consent assumed; no sending if the source is missing; real test of the opt-out mechanism. When an input is unknown, the tool flags the missing evidence instead of choosing the most favourable outcome.
Scenario: B2B email and CNIL
A software vendor wishes to contact maintenance managers regarding an intervention tracking tool. The segment excludes non-directly related functions. Each line contains the employer's SIRET, the published position, the source of the address and a short reason. The message explains the business purpose without pretending to know the site’s equipment. The opt-out link is tested with an internal address, and the “not concerned” responses populate two distinct fields: contact opt-out and role mismatch. This way, compliance and improved targeting are not confused.
Working method: Preparation of a B2B campaign
1. Define the professional problem being addressed and the functions that really impact this problem. Too broad a list of positions makes relevance impossible to justify. To validate this step, note “object linked to the targeted profession”. The risk to avoid is: segment only by seniority or approximate title.
2. Document the source of the address, the date of collection and its generic or named nature. Do not guess an address from a name without scenario validation. To validate this step, note “source and collection date available”. The risk to avoid is: hiding the unsubscribe in an image.
3. Write a targeting reason in a factual sentence, based on the function or activity verified and not on a personal characteristic. To validate this step, note “identity of the sender visible”. The risk to avoid is: reimporting an opted-out contact from another file.
4. Clearly present the identity of the sender, the purpose of the message and how the contact details were obtained when the information must be provided. To validate this step, note “information adapted to the collection method”. The risk to avoid is: interpreting silence as agreement.
5. Add a frictionless opt-out mechanism and test its operation before sending. A manual negative response should be treated with the same priority. To validate this step, note “simple opt-out tested”. The risk to avoid is: segment only by seniority or approximate title.
6. Immediately synchronize opt-outs with all the tools that could reintroduce contact, then check a sample before each new campaign. To validate this step, note “negative response propagated to connected tools”. The risk to avoid is: hiding the unsubscribe in an image.

Decision and operational handoff
Authorize sending when the function, offer and source are documented and the opt-out works. Place on hold addresses whose professional nature or origin is not established. Remove people who opted out from the sending workflow, while keeping the minimum necessary in a dedicated list to avoid further solicitation. If the case falls outside of B2B or involves data collected in an unexpected context, have the legal basis re-examined.
