What's the difference between a solo ads list and a warm list?

A solo ads list is typically built using paid traffic sources like solo ads and often focuses on small commission offers. These lists tend to have a lot of emails and lower engagement. On the other hand, a warm list is built through more organic methods, like social media, and consists of people who have some level of relationship or trust with the sender. They often have higher open rates, click rates, and are more receptive to high-ticket offers.
