The Data score on email verification APIs: How often the call judges an address right, out of 100: valid when it gets mail, invalid when it bounces. Real addresses count for half the score and bounced addresses for the other half. A call scores 0 if it calls no bounced address invalid. It also scores 0 if it calls no real address valid. A call that never asks the mail server about the address scores 0 too. A catch-all, unknown or risky answer counts as not right. Each wrong answer also cancels one right answer. A valid answer counts even when the call also says the domain is catch-all. 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. We don't compare a provider with a call that scores 0. A call that scores 0 tells us nothing about which addresses are hard. A provider we called more than once on the same address is scored on all those calls, so no one run decides it. We lower the score when we test the call on fewer addresses than the benchmark has.
