Email finder
An email finder is a tool that runs a waterfall across data vendors to locate a verified work email, personal email, or mobile number for a specific contact, then stops once it finds one that passes verification.
An email finder runs a waterfall across a set of data vendors looking for one specific thing: a verified work email, a personal email, or a mobile number for a named contact. It stops as soon as it finds one that passes verification, rather than returning every possible match from every source it checked. FullEnrich is the clearest example of a tool built to do exactly this and nothing else: a waterfall across, in its own words, "20+ premium vendors," with no workflow builder or scoring engine of its own, though it does connect out to HubSpot and Salesforce.
Standalone finder, or one step inside a bigger waterfall
The same tool can play two different roles depending on what sits downstream. A small team that just needs contacts today can run an email finder standalone and start calling and emailing within the hour. A team that needs the enriched contact to feed a scoring model, a routing rule, or a CRM sync usually wants that same finder running as one step inside a broader orchestration layer like Clay, called when an earlier source in the sequence comes back empty rather than as the whole system.
In practice
Cost math matters at the field level here, not just the subscription level. FullEnrich's own pricing charges per field rather than a flat per-lookup rate: a work email costs one credit, a personal email costs three, a mobile number costs ten, on a Pro plan running $55 a month for 1,000 credits as of July 2026. A finder that looks cheap on emails can burn through a credit balance fast if a workflow leans on it heavily for phone numbers.
What people get wrong
Teams compare finders on total vendor count instead of find rate for the specific persona and geography they're chasing. A finder connected to fewer sources but tuned for the right slice of people beats one with a longer vendor list aimed at the wrong ICP, the same curation-over-headcount logic that shows up everywhere else in an enrichment stack.
