How to track the behavior of a user who has registered on the landing?

Question

Conversion

I have a land; there are counters; there is a goal (clicking on the send button - which asks for the mail address and name); there is a base for sending letters with offers of new products. How can I bind the address that the user sends to the statistics? that is, I need to know not only how many people subscribe to the newsletter, but also their addresses (I work with different channels, I need to know which address came from which channel).
