How to contact customers actively?

I think the best way to get in touch with this customer as soon as possible is to call him. The function of calling is to keep close contact with customers. If you don't know him, you are afraid that he will cheat you. When you call, communicate with him as much as possible and get to know this customer as much as possible. If the other party is interested in your product, in addition to explaining to him how good your product is, you should also arrange a specific time to meet him. The chances of closing the deal will increase a lot. If the other party doesn't have time to come out for the meeting, you can bring his company address, but remember to bring more people to the meeting. When you call, you should introduce yourself first, and then tell him that we have met, so as to impress him deeply. Then you can ask him if he is still interested in your product. In fact, if you are not good at your own expression, you'd better buy a book of this kind, which will help you in the future.
