What is lead email?
A lead email is the personal or work email of an individual prospect (e.g. jane@acme.com). It's the single highest-value input in B2B enrichment because most data providers use the email as the primary lookup key against their person-graph. From a single email you can resolve the prospect's full name, LinkedIn profile, job title, company firmographics, phone number, and dozens of other fields.
In the context of full name-based prospecting, lead email sits downstream: you start from the full name as your lookup key, the resolver maps it to the matching record in the source graph, and the lead email value is returned as part of the enrichment payload. The accuracy of the lead email you get back depends on how cleanly your full name input identifies the underlying entity.
