I've been doing a lot of research into list building recently, and today purchased a great course from Igor learning the basics of list building, funnels etc.
It suddenly clicked to me that my dad has quite a large list already, and he does no marketing on it whatsoever. They are all opt ins( many offline options as well), and the niche is quite specific, so I think there could be potential here but I'm not sure.
My dad is clueless when it comes to internet marketing, and he asked that I show him proof that there could be potential earning possibilities from this list. It may be that it wouldn't do too well, or it could do amazingly, you never know, but I'd be interested in hearing your thoughts on this and how I should approach my dad about using this list. He has around 4000 people on this list, so I'm not sure if that's enough to get started or not but I thought I'd ask you great Warriors
Thanks in advance,
