Emails List/Database (Country targetted & Industry targetted)

Hi Onehackers!

I wanted to know is there any cheap market for emails databases/lists? Like this one
They are selling emails lists/databases like USA Emails Lists, USA Homeowners Email List, USA Accountants Emails List.

I just wanted to know, is there any website or method i can get those lists for free? Or at cheap price?
Any suggestions will be highly appreciated!

Thanks & Regards!

Tried a few but they seem to sell outdated lists, is more but you get what you pay for as they make their own lists and dont resell older stuff
