? Conversion rate (Sales) per List

Hello,

We use your plugin for collecting leads via a magnet lead. Someone subscribes to a list “Leads” and receives 30 welcome emails. The goal is to sell a product. That is the moment when someone becomes a customer. I can not figure out how many Woo sales were made from the whole subscribers list (not per email).

What is the conversion rate per day, per months, per year of one list?

The whole point of marketing is to get to know how much it costs to get one new customer.
Paid traffic > Leads (CR lead magnet) > Customer (No CR from Mailpoet)

How to solve this?

As long as there is no Conversion rate (Sales) per List like in klaviyo (or am I wrong?), Mailpoet does not fit marketing needs.
