FAQ

Frequently asked questions

Why do contact-data vendors add reverse email lookup?

Add a mobile source without adding wrong-person numbers. Products like yours are judged on valid finds per dollar, which is why the cost that counts is per result that reaches the right person. Run your own sample to see what reverse email lookup returns for your users before you build on it.

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 inputs does it take and what does it return?

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.

Can our users see Forager data in our product?

Yes, under platform terms. Self-serve plans cover internal use by your own team. Showing Forager data to your users, or passing records on, is licensed separately: talk to sales about volume and which fields your users need to see.

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.

Can contact-data vendors test reverse email lookup for free?

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 accurate is Forager data?

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.

Where can I use Forager reverse email lookup?

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.
