Don’t get us started on this. Just because we’re awesome people sometimes think we’re all knowing and have every contact ever in our database. That’s not how this type of data works. If your looking for an email for a guy that used to work with a friend of your second cousin, we probably don’t have it.
We have a very large data set, but if you search for a specific contact it’s unlikely we will have that exact person in our database. The purpose of TopData Search is to find contacts within your target audience, if your target audience is one specific guy your probably in the wrong place.
