Opt out for telemarketing lists

We said it before: all our data is GDPR proof and compliant. But we don’t stop there. Because in each country you have to care of companies and consumer who don’t want to be called anymore. This is a so called A Robinson list or Mail Preference Service (MPS). These opt-out telephone list is an opt-out list of people who do not wish to receive marketing transmissions. In each country these lists are different. In The Netherlands there is the don’t call me register. With each Dutch telemarketing campaign you will have to remove everyone that is registered in the Bel Me Niet Register. Contact us for more information about deduplicating with local Robinson lists.

Code of conduct for telemarketing directories

So there’s the GDPR and local Robinson lists. What else is important?

To guarantee the quality of unsolicited commercial telephone calls, telemarketing companies have drawn up rules themselves. These rules are set out in the Telemarketing Code. Within the Telemarketing Code, a distinction is made between the Telemarketing Advertising Code and the Telemarketing Code of Conduct.

  • Telemarketing advertising code

The telemarketing advertising code contains rules that relate to commercial telephone conversations. For example, a telemarketer must clearly state on behalf of which company he or she is calling. And the telemarketer may not make offers to people he or she suspects are under the age of 16.

The Telemarketing Advertising Code also describes the times at which the telemarketer may call someone and how the right to object and the do not call me register must be offered.

Buying telephone directories for market research

You may call anyone unannounced for market research. You do not have to take the Do-me-not Register into account. The reason for this is that conducting market research is not a commercial purpose. For this reason, companies may approach everyone unannounced.

Private individuals can do something about this, private individuals can register with the MOA research filter. The MOA research filter is the Bel-me-not register for (market) research. As soon as someone registers for the MOA research filter, he / she may no longer be approached by telephone for (market) research unannounced.

The MOA research filter only applies to unannounced market research. If you inform the person in advance, for example by means of a letter requesting participation in telephone research, you may approach this person regardless of his or her registration with the MOA research filter.
