I'm going through a ton of material on list building right now and got curious.
I know of a lot of good marketers and products on list building. I mainly listen to guys like Andre Chaperon, Frank Kern and Brent Hall.
But I don't know about any WSOs about list building that are really good.
I was hoping you do!
Please just take a second and write the name of your favorite WSO on list building. It'd also be cool to know what you liked about it.
