Hi Sharique,

The system you describe sounds very similar to FindThatLead.com (and similar tools). I happen to be a user of Find That Lead and it works really well. Of course, it needs a target to ideally have a company email rather than a Gmail, Yahoo, etc email. It's great for verifying target emails.

It sounds like you want to use your tool to verify mass lists. I think that would be useful for data brokers and services that maintain large industry-wide lists like Agency Access, and other direct media databases.

That is where I would start. Look for companies that compile these lists and offer to test your product using their source lists. If they are happy with the results, you can then sell them ongoing access.
