# Person Linkedin To Email Waterfall

> Resolve contact email from a LinkedIn profile URL only. Shows the exact input shape, output fields, cost notes, and Deepline CLI examples.

In Claude Code, type:

```
/deepline-gtm Find the work email for this LinkedIn profile: linkedin.com/in/janesmith — she's at acme.com
```

```
/deepline-gtm I have a CSV with LinkedIn URLs and domains. Find work emails for each person.
```

<Accordion title="CLI command">
  ```bash theme={null}
  deepline enrich --with '{"alias":"email","tool":"person-linkedin-to-email","payload":{"linkedin_url":"https://linkedin.com/in/janesmith"}}'
  ```
</Accordion>

## How It Works

Providers are tried left to right. The first one to return a result wins — the rest are skipped.

## Parameters

| Name           | Type     | Required | Description                                                                          |
| -------------- | -------- | -------- | ------------------------------------------------------------------------------------ |

| `first_name`   | `string` | Yes      | Contact first name required for deterministic fallback providers.                    |
| `last_name`    | `string` | Yes      | Contact last name required for deterministic fallback providers.                     |

## Cost

**0-7 credits** — waterfalls stop at the first match, so you only pay for the provider that returns a result.
