Frequently asked questions

What is telemarketing?
In a nutshell, telemarketing means recommending or selling products or services by telephone through direct contact. Through telemarketing you can reach your prospects or potential customers and convert them into leads, visitor appointments and better business results.
Convins carries out qualitative telephone acquisition with potential clients and strives for a long-term cooperation. We also provide you with the information you need to close the deal.
How does telemarketing work?
For telemarketing to be successful, specialised knowledge and good preparation are required. Before we start, we first learn about your organisation. This way we are always able to answer questions of (potential) customers. We have natural conversations, so call scripts are not an issue for us. We find out valuable market information and gauge customer interest. And contribute to lead generation. Because we are convinced of our own knowledge and strength, we work on a no cure, no pay basis. Until we have made a valuable appointment, you do not have to pay anything. In this way, you can be sure that the agreements made will be useful to you.
What are the advantages of telemarketing?
Telemarketing is all about entering into a dialogue with new customers, learning more and anticipating their needs. By properly fulfilling the wishes of (potential) customers, a connection is found. The following are of great importance: personal contact, the ability to ask questions and room for interaction.
