  2. Map email-in requests to POST /person_detail_reverse_lookup/by_email/

  2. Compare full_name and linkedin_info.public_identifier with the stored contact and flag mismatches
  3. For mismatches with a LinkedIn URL, fetch the right address with POST /person_contacts_lookup/personal_emails/ and read validation_status

Which B2B data providers workflows use reverse email lookup?

Reach SMB owners who have no professional profile, resell person and reverse-email enrichment through a developer data API and check that a personal email belongs to the expected person. Each is on this page with its trigger, steps and outcome.

How do I reach restaurant owners personal cell?

Start from known owner identifiers (business email, phone or name) on the local-business record. Retrieve personal_email and mobile via /personal_emails/ and POST /person_contacts_lookup/phone_numbers/.

What do I send, and what comes back?

You send company domain, email and local business record. You get back company profile, match (bool), matched person and owner personal_email, from POST /person_detail_reverse_lookup/by_email/, as JSON.

Am I charged when nothing is found?

Yes. Reverse email lookup is charged per request, whether or not data comes back. Only mobile and email lookups are free when nothing is found, so try your inputs on a small run before you scale.

Is there a free way to try Forager?

Yes. Create a free account at app.forager.ai: it comes with $5 in free credits and an API key, and there is no credit card to sign up. Run it on records you already know, or book a demo and send us a list: we run it and show you what we find.

Which provider can power a reverse email lookup API I resell?

The workflow uses Forager Person enrichment, Company enrichment, Reverse email lookup and Personal emails. Person enrichment: A full professional profile for a person from a LinkedIn URL, email or phone: experience, education, skills and contact channels. Give a developer-focused data API a pay-per-result person, company and email-to-person endpoint without building its own people graph.

How do you check data quality?

The test that counts is your own: send a list of profiles you care about. We run it and show you what we find, number by number, so you can measure hit rate and connect rate yourself.

What is the difference between a reverse email lookup and an email finder?

An email finder starts from a person and returns their email. A reverse email lookup starts from an email address, such as a sign-up or an inbound lead, and returns the person behind it: name, title, company, location and social links.

Does Forager integrate with the tools we already use?

Native in Clay, partner-built in Deepline and called through the API from Make, n8n and your own code. Everything else connects through the REST API with one API key.

Is there a contract or minimum commitment?

No contract to start: a free account comes with $5 in credits. To keep using reverse email lookup, choose a monthly or yearly plan. Monthly plans cancel anytime and unused credits roll over; yearly plans grant all credits upfront and cost 10% less. Larger volumes are agreed with our team.
