Customer database: which service providers should you choose?

Base de données clients : quels fournisseurs de service choisir

When you start your business or decide to give it a little boost, it takes hard work to expand in a new market or reaffirm your control over an existing territory. For this, a good management of customer data is essential. Your customer data drives your company's business through compiling valuable data to track your sales and analysing your economic performance.

However, it is sometimes necessary to get a little help from the outside. It can happen that the first-party data you own is unusable, lost or obsolete. That is why it may be easier to create a new base rather than waste weeks cleaning data entangled in a plethora of systems and tools that are not centralised.

To (re)build your address book and professionalise your customer data, data professionals are at your service.

What you need to know before using a third-party provider

GDPR Compliance

The General Data Protection Regulation (GDPR) is a European law that came into effect on May 25, 2018. It is particularly important for how data is collected, compiled and secured. All the data you want to use must comply with the GDPR or you will face complex court procedures and heavy fines. In addition, don’t forget that your responsibility is engaged, whether you use an external supplier or subcontractor or not. Choosing the right provider is essential if you don’t want to find yourself in a contentious situation.


Searching, collecting and verifying the relevance of data is important It requires a verification and lead generation work that can be manual or automated. In any case, you don't need to do it yourself but you do have to invest money in it.

In terms of customer data, low cost is rarely a relevant option. You risk ending up with barely usable data, many useless email addresses and a matching that does not match your expectations and your targets. You also risk damaging your reputation and image by sending poorly targeted messages, which will have a direct impact on your KPIs (deliverability rate, open rate, spam, etc.).


With the Internet, everything can be done in three clicks.

However, nothing beats the human relationship to discuss your problems and find the right solutions. Some providers on the other side of the world who know neither your sector nor your specificities are ready to sell you data to enrich your lists of prospects.

To avoid disappointment, choose local companies and trusted intermediaries. We therefore advise to find service providers whom you can meet, whose legitimacy you can verify, and who are able to advise and support you from a strategic point of view in your approach.
