Very interested in how you grew your list.
I've recently bought traffic and tbh, I don't they are unique traffic as they barely stay on the page, and the number of impressions I've got vS converstions is super low.
Mind you this is more to have someone actually buy something not build an email list, but the mechanism you used to get your traffic is pretty cool.
Is it possible that solo ads are better in terms of conversions then just mass pumping global traffic across?
Sorry - probably wrong place to ask, but you have some serious experience/knowhow
Shall continue watching and learning from your journey.
