I'm looking for a good site to buy email list.

It depends on the situation. So many people read that buying data is bad and then just preach it as if it is the truth.

I've been buying data for over 16 years and depending on the vertical, buying data beats building your own list any day. However, if you are in some small niche and your offer requires a purchase to be made, then building a highly targeted opt-in list is probably the way to go.
