Real-time email discovery API with live SMTP verification
What is emailfinder.dev?
emailfinder.dev is a real-time email discovery API that finds and verifies professional email addresses. Unlike services relying on stale databases, every lookup performs live SMTP verification at the moment you request it, ensuring 100% deliverability.
Simply call a REST endpoint with a name and domain, a company name, or a LinkedIn profile URL. You only pay when we return a valid, verified email—if we can't find one, the lookup is free. Credits never expire, and the API is built for scale with a 1,000 requests/minute rate limit and a 3-second average response time.
Key features include:
- Real-time SMTP verification on every lookup
- Pay only for successful discoveries
- Endpoints for person, company, LinkedIn, and decision maker
- REST API with JSON responses and full documentation
