Then, you can sell valid customer information to those organizations. If your customer information is very accurate and these customers have the potential to sign the bill, then the organization can also spend a lot of money to buy your information. So when you collect personal information, you must accurately grasp and collect those effective information, instead of wasting the gifts you have prepared. Then, after getting certain customer information, you have to do a screening and integration yourself.
First, eliminate meaningless information, and then make a classification to understand the customer's intentions first. For example, they may sign up for fish and shrimp, and some children may sign up for some cram schools. So, we can classify them, and you can also sell them to different organizations without wasting any resources.
In addition, don't sell some false information just to make money, then you are doing a one-off business. In this way, I believe that local institutions will pull you black for a long time, and some people with strong awareness of rights protection will use legal channels to solve problems, which is definitely not worth the candle for you. So do it if you want. The most important thing between people is to build trust.
