# Find the Email Format of Any Company by Domain

**Use case:** 

Paste company domains and get the email format each one actually uses, such as first.last@ or flast@, with an example, how many current employees confirm it and how far they agree. The format comes from addresses on record, not from a guess. Up to 5,000 domains per run; a domain without a confirmed format is a free row that says why.

## Input

```json
{
  "domains": [
    "stripe.com",
    "n26.com",
    "linear.app",
    "hubspot.com",
    "gong.io"
  ],
  "sampleLimit": 200
}
```

## Output

    "label": "Status",
    "format": "string"
  },

## FAQ

### How does the email format task confirm a format?

The email format task reads current employees' addresses on record at the domain and counts which pattern they follow. The output shows the format, people confirming it, agreement and other formats seen.

### What if a company uses more than one format?

The email format task returns the dominant format with its agreement share, and lists the other formats seen, so a mixed domain is visible instead of hidden.

### Do I pay for domains without a confirmed format?

The email format task charges only per domain that returns a confirmed format; every other outcome is a free row that says why. The price is on the Actor's Pricing tab.

### What does Sample limit change?

Sample limit sets how many current employees the email format task reads per domain, 50 to 500. More employees means more confirmations on large companies, at the same price per domain.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/b2bsearch/company-email-format-finder.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
