The Data score on reverse email lookup APIs

How often the call names the person behind a work email, out of 100: the share of the addresses we called for which it gave that person's own LinkedIn profile. We called only addresses whose owners wrote to us from them, and found each owner's LinkedIn page ourselves, so no provider's answer is taken as the truth. A provider called on fewer addresses is set against how the others did on those same addresses, so an easier few don't lift it. A provider we called more than once on the same address is scored on all those calls, so no one run decides it.
