Where can I find email databases?

[Miril]

The internet is full of information and there are plenty of email lists providers. I was looking for a database that consists of US Yellow Pages Dataset and business emails. To be honest, I practice this method not the first time because it's definitely effective. What email marketing strategies are worth trying?
