Extract a business email address for each unique person. Two sources, and the output records which via contact.source.
FREE: an address published in the public LinkedIn text this Actor already reads — their About section or their employer's description. Costs nothing and is never charged. Most people publish no address.
PAID (requires a PAID Apify plan — on the Free plan this step is skipped entirely, nothing is charged, and the free extraction above still runs): the person's name and their employer's mail domain are sent to a third-party email finder. That provider is NOT LinkedIn, and such an address is labelled contact.source 'enrichment'. You are charged ONLY when the provider returns an address it has CONFIRMED to be deliverable.
UNCONFIRMED ADDRESSES ARE DISCARDED, NOT RETURNED. Many large employers run mail gateways that accept every recipient, so no provider can confirm whether a mailbox exists there — and a provider asked about such a domain will return a pattern-derived address for any name at all, including one belonging to nobody. Those are dropped rather than handed to you, and never charged. The consequence is real: expect an empty email column for a substantial share of people at large enterprises, by design.
Each unique person is looked up at most once per run. Duplicates, filtered profiles and skip-list matches are never looked up. People whose employer domain we could not resolve cannot be looked up at all — the run log reports how many.
