## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Email Verifier & Validator

Bulk-check email lists before your next lead-generation, outreach, or CRM cleanup campaign. The Actor validates address syntax, identifies common free and disposable providers, detects role-based mailboxes, resolves MX records, and assigns an easy-to-filter deliverability score and status.

The Actor uses Node.js DNS resolution and a built-in disposable-domain list. It requires no API key, paid data provider, or proxy.

### Input

| Field | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `emails` | array of strings | Yes | Sample list | Email addresses to validate. |
| `checkMx` | boolean | No | `true` | Resolve mail exchange records for syntactically valid domains. |

Example input:

```json
{
  "emails": [
    "jane.doe@gmail.com",
    "ceo@stripe.com",
    "noreply@disposablemail.com",
    "bad@@format"
  ],
  "checkMx": true
}
```

### Output

Each input email produces one dataset row containing:

- The original `email`, lowercase-and-trimmed `normalizedEmail`, `domain`, and `localPart`
- `syntaxValid`, `mxFound`, and the highest-priority `mxHost`
- `isFreeProvider`, `isRoleBased`, and `isDisposable` flags
- An integer `deliverabilityScore` from 0 to 100
- A `status` of `deliverable` (70–100), `risky` (40–69), or `undeliverable` (0–39)

Example output:

```json
{
  "email": "jane.doe@gmail.com",
  "syntaxValid": true,
  "normalizedEmail": "jane.doe@gmail.com",
  "domain": "gmail.com",
  "localPart": "jane.doe",
  "isFreeProvider": true,
  "isRoleBased": false,
  "isDisposable": false,
  "mxFound": true,
  "mxHost": "gmail-smtp-in.l.google.com",
  "deliverabilityScore": 100,
  "status": "deliverable"
}
```

### Scoring

Every address starts at 100 points. Invalid syntax subtracts 100, no MX record subtracts 60, a disposable domain subtracts 50, and a role-based local part subtracts 10. The final score is clamped to 0–100.

MX records confirm that a domain accepts email routing, but they cannot guarantee that a specific mailbox exists. Use the score as a practical screening signal rather than proof of inbox delivery.

# Actor input Schema

## `emails` (type: `array`):

Email addresses to validate. Add one address per line.

## `checkMx` (type: `boolean`):

Resolve each valid domain's mail exchange records.

## Actor input object example

```json
{
  "emails": [
    "jane.doe@gmail.com",
    "ceo@stripe.com",
    "noreply@disposablemail.com",
    "bad@@format"
  ],
  "checkMx": true
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "emails": [
        "jane.doe@gmail.com",
        "ceo@stripe.com",
        "noreply@disposablemail.com",
        "bad@@format"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("technicaldost/email-verifier").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});
