Best Whois email extractor

I am searching for best whois email extractor If free that would be better ?

 

I get what it does, but what exactly do you do with the information it extracts if you don't mind me asking? Ive never even heard of a whois email extractor before this lol. And sorry, i dont know of any other than what you can pull off google, so no previous experience here

 

It can be used to generate leads from the information extracted

 

You can use free domaintools for better email extractor.

 

Where do I find a free one?

 

Hi. I can't seem to know which one you're referring to. There are several but all trials or only allow you to enter one address

 

Hey , you can find those tools from Here, look under Email Business Software section, but it's not free , FYI
