# Email finder by domain: run it free, or from your agent

Up to 3 public work emails at a company domain, with name, job title, confidence and the email pattern.

## Prompt

Use looot to find work emails at these companies: [paste domains, one per line]. 1. Set up https://looot.ai/skill.md. 2. Search the catalog for an endpoint that finds email addresses at a domain and check its price per result before you call. 3. Run it with a small limit per domain and the department I name. 4. Return a table of domain, email, name, job title and confidence, and give the total cost.

## What it needs

A company domain, and a department if you want one

## What comes back

- email address
- first and last name
- job title
- confidence score from 0 to 100
- last verification result
- the company's email pattern, such as first.last

## Endpoints and providers

- hunter: hunter-domain-search-get

## What it costs

The tool on the web page runs live at no cost to you and is limited per hour. The results come from public data through looot. For heavier or repeated use, run the same job from your own looot account: looot bills per call and charges nothing while your agent is idle. The live price comes from the catalog and shows on the web page.

## Reach the right team

Filter by sales, marketing or executive and find who to write to.

## Learn the pattern

See the company's email pattern, then build any address with the email permutator.

## Check before sending

Open each address in the email checker before it goes into a campaign.

## Scale with an agent

Your agent runs the same search for a list of domains and shows the cost first.

## How do I find email addresses for a company domain?

Type the domain in the box at the top of this page. The tool asks Hunter for the addresses it has found at that domain in public sources and shows up to 3 with names and job titles.

## Is this email finder free?

Yes. Each search in the box costs you nothing and is limited per hour. It returns at most 3 addresses per run, because the provider bills per address. Your agent can ask for more from your own looot account at the per-result price shown above.

## Where do the email addresses come from?

Hunter collects addresses published on web pages and generates likely ones from the company's pattern. The table shows its confidence score and its last verification result for each one.

## What does the confidence score mean?

Hunter's own score from 0 to 100 for how likely the address is right. Treat anything below about 70 as a guess and check it with the email checker.

## Do you store the domain or the emails?

No. This page does not save or log the domain you type or the addresses that come back. The domain is sent once to Hunter through looot, and the result goes only to your browser.

## Why do I see the same few people every time?

Hunter sorts by its own ranking, and this page shows the first 3. Pick a department to see other people. Your agent can page through more results.

## What if the domain is catch-all?

The table says so in its title. A catch-all domain accepts mail for any address, so a valid verification there does not prove the person reads it.

## Can I search by company name instead of domain?

Not on this page. Type the domain. If you only have a name, find the website first with the company lookup tools on this site.

## How do I run this from an agent with looot?

Give your agent the skill.md link from the prompt above. It calls the hunter-domain-search-get endpoint with the domain, a limit and an optional department, and reads the emails list.
