# Verify Email

> Check an email address with MillionVerifier.

**Verify Email** sends one syntactically valid email address to
MillionVerifier and returns its deliverability quality.

## Inputs

| Input                   | Type                    | Required | Description                        |
| ----------------------- | ----------------------- | -------- | ---------------------------------- |
| **Third-party account** | MillionVerifier account | Yes      | The API key used for verification. |
| **Email**               | String                  | Yes      | The address to verify.             |

## Output

| Output      | Type   | Description                                                   |
| ----------- | ------ | ------------------------------------------------------------- |
| **Quality** | String | `good`, `bad`, or `risky` when the service provides a result. |

The output is empty when MillionVerifier returns an empty or missing quality.

<Tip>
  Treat `risky` as a separate branch instead of silently accepting or rejecting
  it. The right policy depends on whether you are validating signups, cleaning a
  list, or protecting a transactional send.
