How can i monetize 3 million email real persons list?

I'm really sorry if this isn't the right place for this thread , if necessary i deleted and place it wherever you want.

So i got this list , all around the world i don't know how to monetize it for real...

Well other than trying to sell it for like $20 or something or getting a setup to spam them what else could you do?

Untargeted email list is not that big of a deal.
