# Best cached email verification API in 2026

> We benchmarked 10 cached email verification API providers. We list the three we score highest. For each one, we show its top scoring plan, each part of the plan's score and what 1,000 emails cost.

The Data score on Cached email validation: 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. 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. A provider we called more than once on the same address is scored on all those calls, so no one run decides it. Each provider here may answer from a check it made earlier, or check only the domain.
