What Is Enrichment match rate?

Results returned for defined inputs

An enrichment test needs a clear starting set and a stated definition of match. A lookup returning any email address is different from one returning the correct current work address for the named person. A company match, phone result and verified email result also concern different fields. Keep those outcomes separate rather than reporting one unlabeled coverage percentage across the entire workflow.

A basic calculation divides inputs meeting the declared result rule by the eligible inputs submitted. Define how duplicates, malformed inputs, provider errors and unfinished lookups are handled. Excluding every failed request from the denominator can make a provider appear to cover more of the original business population than it actually did. Report operational failures alongside successful results so the comparison remains reproducible.

Compare the same population

Run providers against the same representative input set and input quality. Geography, role, company size and available identifiers can affect results. One vendor tested on full names and verified domains should not be compared directly with another given only partial company names. Save the input version and observation period, and prevent earlier providers' results from quietly enriching the test inputs for later providers.

Measure correctness separately

Inspect an appropriate sample of returned values against independent evidence. A high return rate is not necessarily high accuracy, currentness or delivery reliability. An uncertain catch-all result and a verified mailbox should not receive the same acceptance label unless the test intentionally defines them that way. Preserve the raw provider result and your mapped disposition.

In a waterfall, measure incremental accepted results as well as total results so duplicate discoveries are not counted as new coverage. The useful metric explains what the workflow returned for the population it actually attempted. It does not prove that those contacts are qualified, permitted for outreach or likely to answer a sales message.
