FAQ

Frequently asked questions

How do applicant tracking systems use Forager reverse email lookup?

Update old applicants' current roles and contacts so they show up in new searches and can be re-engaged. Turn an email address into a full person profile: name, title, company, location and social links. This page walks through 3 workflows with the exact steps.

Why do applicant tracking systems add reverse email lookup?

Reach applicants and passive candidates without stale contacts. Products like yours are judged on candidate replies, 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How do I update outdated candidate records in my ATS?

Match ATS records by email with POST /person_detail_reverse_lookup/by_email/ or by LinkedIn identifier. Update current role_title, employer and skills from POST /person_detail_lookup/.

What inputs does it take and what does it return?

You send applicant personal email, ATS export (name, email, LinkedIn URL) and claimed experience. You get back certifications, current employer, current role_title and educations, 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 applicant tracking systems 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.

How do I enrich job applicants with work history?

Resolve the applicant email with POST /person_detail_reverse_lookup/by_email/. Map roles, educations, skills and certifications onto the candidate profile fields.

How do I know the data is right?

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.
