LinkFinder AI's reverse email lookup API takes any email address and returns the person behind it — full name, job title, company, location, and verified social profiles. Identify unknown contacts, enrich inbound leads, and de-anonymize signups in real time.
Send any email address and the API returns the person behind it: full name, job title, seniority, location, and verified social profiles, plus a nested company object with name, domain, and industry. Each result carries a confidence score.
Does it work with personal and free email providers?
It works best with business email addresses, where match rates and company data are strongest. Free webmail addresses such as gmail.com may resolve to a person but won't return company firmographics. You only pay for successful matches.
How accurate and fresh is the data?
We maintain 95% match accuracy across more than 500 million indexed profiles, continuously re-verified against multiple sources. The confidence score lets you set your own threshold for automated decisions.
What's the rate limit for lookups?
Standard plans include 1000 requests per minute with burst capacity up to 2000 requests. For bulk enrichment, enterprise customers can request higher limits and batch endpoints sized to their volume.
How do you handle data compliance and privacy?
We're SOC 2 compliant and follow GDPR guidelines for all data processing. Data is sourced from publicly available business information, and we provide opt-out mechanisms for individuals when required.
