# Best cached reverse email lookup API in 2026

> We benchmarked 4 cached reverse email lookup 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 people cost.

The Data score on Cached reverse email lookup: 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. Each provider here answers from a copy it keeps.
