Domain Search
Search any company domain and get up to 20 verified professional email addresses at that organization. Every result is confirmed deliverable via live SMTP — no stale databases, pay only when emails are found.
Search a domain, get verified contacts
The domain search endpoint is the fastest way to build a contact list at a target company without knowing individual names. Pass a domain — or a company name — and receive up to 20 verified professional email addresses in seconds.
Unlike databases that store snapshots of email addresses crawled months ago, emailfinder.dev verifies each result against the live mail server at the time of your request. You only receive addresses that are confirmed deliverable right now.

Domain search FAQ
What is a domain search?
A domain search takes a company's web domain (like stripe.com) and returns all the professional email addresses associated with that organization that can be found and verified. It's used to discover multiple contacts at a company without knowing specific names.
How many emails does a domain search return?
The emailfinder.dev company endpoint returns up to 20 verified email addresses per domain. All returned emails are confirmed deliverable via live SMTP at the moment of the request — not pulled from a database.
How is domain search different from finding a specific person's email?
The person endpoint finds a single email from a full name and domain. The company (domain search) endpoint returns all discoverable verified emails at the domain — useful for multi-threading outreach or when you don't know specific names to target.
Can I search by company name instead of domain?
Yes. The company endpoint accepts both domain and company_name parameters. If you only have the company name, the API will attempt to resolve the domain automatically.
How much does a domain search cost?
Domain searches use the company endpoint, which costs 5 credits (from €0.045 at the highest volume tier). If no emails are found for the domain, you are not charged.
What types of email addresses does domain search return?
The company endpoint returns verified professional email addresses at the domain — typically employee work emails. It does not return generic addresses like info@ or contact@ unless they are the only verified addresses found.
