In the area of address and lead generation, we work with proven methods such as the double opt-in process. This gives you the conscious consent of potential new customers to specifically inform them with newsletters . With this procedure, the persons addressed actively confirm the storage of their data and consent to be contacted by your company. With German law, you are not only on the safe side. You also avoid the risk of a negative perception of your brand through misguided, unwanted advertising measures outside of your target group. A loss of image of this kind can cost you dearly.
