> [!NOTE]

> Tool ID: `ipqs_batch_email_verify`

## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'ipqs_batch_email_verify',
  {
    "email_batch": [
      {
        "email": "jane.doe@example.com"
      }
    ]
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute ipqs_batch_email_verify --input '{
  "email_batch": [
    {
      "email": "jane.doe@example.com"
    }
  ]
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "status": "example",
  "result": {
    "data": {
      "email_batch": [
        {
          "valid": true,
          "deliverability": "example",
          "disposable": true
        }
      ]
    }
  }
}
```

Use `deepline describe ipqs_batch_email_verify --json` for the latest machine-readable contract.

## Input reference

Verify up to 100 email addresses in one synthetic batch. Deepline runs at most 5 IPQS checks concurrently, so larger batches can be slow. 0.070 Deepline credits per email.

| Name | Type | Required | Default | Details |
| - | - | - | - | - |
| `payload.email_batch` | `array` | Yes | — | Array of email objects to verify in batch (1-100). Deepline runs at most 5 IPQS checks concurrently, so larger batches can be slow. Minimum items: 1. Maximum items: 100. |
| `payload.timeout` | `integer` | No | — | Maximum time in seconds to wait for SMTP response (1-60). Minimum: 1. Maximum: 60. |
| `payload.fast` | `boolean` | No | — | Skip SMTP checks for faster results. |
| `payload.strictness` | `0 \| 1 \| 2` | No | — | Strictness level 0-2. Higher = more false positives but catches more fraud. |
| `payload.abuse_strictness` | `0 \| 1 \| 2` | No | — | Abuse detection strictness 0-2. |
