How emailfinder.dev works
emailfinder.dev is a REST API with four endpoints — person email (name + domain), company emails (up to 20 per domain), LinkedIn lookup (profile URL → verified email), and decision-maker by role (CEO, CTO, VP Sales, etc. at any company domain). Every result is confirmed live via SMTP before it's returned to you.

}Prospeo alternatives FAQ
What is the best free Prospeo alternative?
emailfinder.dev offers free credits on signup — no credit card required — so you can test all endpoints before purchasing. It's one of the most accessible Prospeo alternatives for trying before committing.
Does emailfinder.dev work as a Prospeo replacement for API use?
Yes. emailfinder.dev is built API-first with four GET endpoints, Bearer token auth, JSON responses, and a 1,000 req/min rate limit. It's a direct drop-in for any workflow that currently calls Prospeo's API.
How does emailfinder.dev verify emails differently from Prospeo?
emailfinder.dev connects to the recipient's mail server via SMTP on every single request and confirms the mailbox exists before returning the result. This is real-time verification — not a cached database lookup. The result is zero false positives: if the email can't be confirmed, you get not_found and pay nothing.
