## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Bulk Email Validator

Clean your email list before it costs you. Validate up to 500 addresses per run — format check, MX record lookup, and disposable domain detection — for $0.01 each.

Bad emails bounce. Bounces hurt deliverability. Disposable signups waste your sales team's time. Fix the list before it becomes a problem.

### Features

- **Format Validation**: Checks email syntax using RFC-compliant validation
- **MX Record Lookup**: Verifies that the domain has valid mail exchange (MX) records via public DNS
- **Disposable Domain Detection**: Identifies temporary/throwaway email services (mailinator, tempmail, guerrillamail, etc.)
- **Batch Processing**: Handle up to 500 emails per run
- **Caching**: Automatically caches MX lookup results to avoid redundant DNS queries
- **Pay-Per-Email Pricing**: Only pay $0.01 per email validated

### Input

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `emails` | array | ✓ | List of email addresses to validate (max 500) |
| `checkMx` | boolean | - | Enable MX record verification (default: `true`) |
| `skipDisposableCheck` | boolean | - | Skip disposable domain detection (default: `false`) |

**Example Input:**
```json
{
  "emails": ["alice@gmail.com", "bob@example.com", "spam@mailinator.com"],
  "checkMx": true,
  "skipDisposableCheck": false
}
````

### Output

Each validated email produces a result object with:

| Field | Type | Description |
|-------|------|-------------|
| `email` | string | The input email address |
| `isValid` | boolean | Overall validation result |
| `reason` | string | Validation status (Valid / Invalid email format / No MX record found / Disposable email domain) |
| `domain` | string | Domain portion of the email (null if format invalid) |
| `isDisposable` | boolean | Whether domain is a known temporary service |
| `hasMx` | boolean | Whether domain has valid MX records |
| `mxRecords` | array | List of MX server hostnames (if found) |
| `disclaimer` | string | Legal disclaimer about validation scope |

**Example Output:**

```json
[
  {
    "email": "alice@gmail.com",
    "isValid": true,
    "reason": "Valid",
    "domain": "gmail.com",
    "isDisposable": false,
    "hasMx": true,
    "mxRecords": ["gmail-smtp-in.l.google.com", "alt1.gmail-smtp-in.l.google.com"],
    "disclaimer": "This tool validates email address format and checks DNS MX records..."
  },
  {
    "email": "spam@mailinator.com",
    "isValid": false,
    "reason": "Disposable email domain",
    "domain": "mailinator.com",
    "isDisposable": true,
    "hasMx": false,
    "mxRecords": [],
    "disclaimer": "This tool validates email address format and checks DNS MX records..."
  },
  {
    "email": "invalid-email",
    "isValid": false,
    "reason": "Invalid email format",
    "domain": null,
    "isDisposable": false,
    "hasMx": false,
    "mxRecords": [],
    "disclaimer": "This tool validates email address format and checks DNS MX records..."
  }
]
```

### Pricing

**Pay-per-event model:** $0.01 USD per email validated

No setup costs, no platform fees — only pay for what you validate.

### Use Cases

- **B2B Sales**: Validate lead lists before cold outreach campaigns
- **Email Marketing**: Clean list hygiene and deliverability checks
- **Account Signup**: Block temporary/throwaway emails during registration
- **Data Validation**: Verify data quality in imported contact lists
- **CRM Maintenance**: Identify invalid emails in existing databases

### Technical Details

#### Email Format Validation

Uses the `validator` library (MIT License) which implements RFC 5322-compliant email format checking.

#### DNS MX Record Lookup

Uses Node.js native `dns.resolveMx()` to query public DNS servers. Includes:

- 5-second timeout per domain lookup
- Automatic caching to avoid duplicate queries
- Graceful handling of DNS failures

#### Disposable Domain List

Includes 50+ known temporary email providers:

- mailinator.com, tempmail.com, guerrillamail.com
- 10minutemail.com, yopmail.com, sharklasers.com
- And many others (regularly updated based on research)

### Disclaimer

**Important**: This tool validates email address format and checks DNS MX records using open source libraries and public DNS queries. Results indicate **technical validity only** and do **not guarantee**:

- Email deliverability
- Inbox placement success
- That the address is actively monitored or used
- Freedom from bounce or filtering

**Do not use** this tool for:

- Spam, phishing, or unsolicited communication
- Scraping or harvesting email addresses
- Circumventing legitimate email consent mechanisms

Email validation accuracy depends on DNS server availability and may not reflect real-time server status. The operator is not responsible for any commercial or legal consequences of results derived from this tool.

### Data Source

- **Email Validation**: [validator.js](https://github.com/validatorjs/validator.js) (MIT)
- **DNS Resolution**: Node.js built-in `dns` module
- **MX Checking**: Public DNS infrastructure
- **Disposable Domains**: Research-based list of known temporary email services
