Six indicators that sum up B2C coverage in France

Indicator Value
B2C contacts in France 48 million
B2C postal addresses 48 million
Opt-in SMS mobiles 26 million
Households identified 31 million
Opt-in emails 25 million
Dates of birth 28 million

 

These volumes translate an operational reality: you reach nearly every adult consumer residing in France. According to INSEE, France counted 30.2 million households at 1 January 2024; the 31 million households we mobilize include a significant share of second homes and multi-address households. Internationally, we activate the full 2.5 billion individuals identified within our perimeter, across the 197 countries we cover. Every engagement starts with a free audit of your B2C database within 48 hours, delivered with a five-tier data maturity grid.

B2C activation criteria: more than 50 combinable segments

Household

Household data

Composition (couple with children, single, single-parent family, retirees), age of occupants, declared or estimated income where the source allows, housing status (owner, tenant), number of children in the household.

Geolocation

Fine geolocation

Addresses geocoded to rooftop precision, hexavia (street-level segmentation), hexaclé (building-level segmentation), IRIS (INSEE statistical grid squares), catchment areas calculated by drive time or public-transport time. The hexaclé grid distinguishes a high-end condominium from a standard one on the same street.

Purchase intent

Purchase-intent signals

Recent marketplace or comparison-site visits, purchases on adjacent verticals, RFM (Recency, Frequency, Monetary value) on verified transactions, look-alike computed on your CRM database, active subscriptions (press, streaming, energy, telecom).

Demographics

Demographic data and life signals

Age, family situation, profession, time at the address, recent relocations, birth of a child, marriage, retirement. These life signals are the raw material for targeting in insurance, finance and consumer banking.

In total, more than 50 criteria are combinable on a single request. You describe your target, we identify the combination of sources that covers it with the best reachability rate.

Your use cases in consumer acquisition and direct marketing

Postal address

Geolocated campaigns at the hexaclé grid

A food retail chain mobilizes the geolocated postal addresses within a 5 km radius around each store for an opening campaign. We deliver a hexaclé file segmented by household composition and estimated income, with postal addresses geocoded at 100%. You measure a response rate multiplied by three compared to a non-geolocated mailing, and a ROI per campaign directly comparable from one opening to the next.

Opt-in SMS

Mobile first contact on 35 million profiles

Opt-in SMS has become the first-contact channel for consumer campaigns. We mobilize 35 million opt-in SMS mobiles, segmented by age, geolocation and transactional behavior. The measured open rate exceeds 95%, against an average 25% on email — a gap that changes the economics of your acquisition.

Opt-in email

Emails audited on every engagement

The 20 million opt-in emails are audited on every engagement on three criteria: documented legal basis, age of consent, real deliverability observed at routers. You segment by declared interest, verified purchase behavior and demographics. GDPR compliance is audited on every record, opt-in is verified at the source, and the quality of the customer data delivered is measured before every send.

Multichannel orchestration

Four channels synchronized

For high-stakes engagements (product launch, loyalty programme, retention), we orchestrate the campaign across the four channels simultaneously: email, SMS, postal, RCS. The scenario sequentially combines the channels by profile and observed response, with continuous optimization of deliverability and reachability.

Look-alike

Look-alike targeting on 2.5 billion individuals

For look-alike targeting, we calibrate a model on your existing CRM database, then extend it to comparable segments within the 2.5 billion individuals perimeter. You activate these segments programmatically, on social ad networks or in postal direct marketing, depending on the channel that makes sense for your market.

Anonymized case A charity wanted to recruit 80,000 new donors over the fiscal year. We mobilized a coordinated multichannel orchestration: 1.2 million postal addresses segmented by household composition and income, with opt-in emails and opt-in SMS synchronized on the same sequence. The conversion rate reached 6.8%, i.e. +82,000 new donors over the year, exceeding the initial objective.

GDPR compliance in B2C: the highest bar, systematically audited

Opt-in verified

Verified opt-in sources

The legal basis (explicit consent or legitimate interest depending on the case) is documented by source. No non-opt-in source is mobilizable on B2C engagements.

DPO audit

DPO audit on every engagement

The MV Group DPO, at Cabinet Inside Avocats, validates compliance before delivery. You obtain full traceability of the data journey, source by source.

French data protection act

Compliance with the French data protection act

Compliance with applicable CNIL (French data protection authority) obligations, declaration and information to the data subjects.

Right to object

Automated right to object

Any unsubscribe is propagated within 24 hours across every database mobilized in the engagement.

Limited retention

Limited data retention

Maximum 3 years after the last active contact, in line with CNIL recommendations.

This rigor protects your brand as much as it respects your end customers. It is the precondition for sustainable consumer acquisition.
