I ran a pretty niche list from the audience builder (which is awesome btw) of 1600 contacts as a test and it returned accurate results fairly rapidly. I ran them through another email checked and all but 13 verified. Pretty damn good if you ask me.

I’ll run another list of more local leads next and see what happens.

So far quite impressed and plan to update to tier 4.

Nice tool and thanks for bringing it to appsumo.
