Domain Search: every email address at a company domain
Enter a company domain to see the addresses we can find, with names, titles, departments, the source where each one was seen and when.
How Domain Search works
- Enter a company domain such as acme.com.
- We collect addresses from public sources and the domain's pattern.
- Filter by department, seniority and type, then save to a list.
What each label means
Observed Seen directly in a public source, such as the company's website or a registry filing.
Inferred Generated from the company's detected email pattern. Plausible, not proof that the mailbox exists.
Verified The mail server accepted this address and rejected a random one.
Uncertain Checked, but deliverability could not be established either way.
Every result carries a timestamp. An address is never called deliverable just because the domain accepts mail, and verification never sends a message.
Domain Search API
The same tool as an API call, for your own apps and AI agents.
POST /v1/contacts/domain-search/domain (required) | Company domain. |
|---|---|
department | Filter: sales, finance, operations and others. |
seniority | Filter: executive, director, manager and others. |
type | personal or generic (role) addresses. |
Returns. Addresses found at the domain, each with name and title where public, its status, the source it was seen in and when, plus the domain's email pattern.
Questions
