Funnel for cold traffic with a return on investment of 388%

We have gathered and launched a funnel for cold traffic in a solid niche (SMM). The funnel includes free and paid mini-products. In the screenshot - the return on investment over two months (November-December). In January (as of now) we have a return of 420%.

I am assembling funnels turnkey - from idea to launch and analytics of results (which is super important for understanding effectiveness and points of growth and scaling).
