## 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.

### 🔍 How the 6-Layer Verification Engine Works

Each email address is processed through a series of deep validation checks:

1. **Syntax Validation**: Checks if the email follows standard formatting rules (RFC compliant).
2. **Domain & MX Checking**: Confirms if the domain is active and has valid Mail Exchanger (MX) records to receive mail.
3. **Office 365 Directory Handshake**: Special protocol check to validate Microsoft/O365 mailboxes with 100% accuracy.
4. **SMTP Connectivity Check**: Establishes a temporary connection to the recipient's mail server to check mailbox existence without sending a real email.
5. **Disposable & Burner Filter**: Flags temporary burner accounts (e.g. Mailinator, TempMail) to prevent spam signups.
6. **Role Account & Free Email Detection**: Detects functional group emails (e.g., info@, support@) and free providers (Gmail, Yahoo).

***

### 📥 Input Configuration

Input is extremely simple. You only need to configure:

- **Emails Input List (`leads`)**: Paste your list of emails (one address per line).
- **Concurrency Limit**: Maximum number of parallel workers (default is 5).

***

### 📤 Dataset Output Schema

The results are saved directly to your default Apify Dataset. Below is the detailed schema:

| Field | Type | Description | Example Value |
| :--- | :--- | :--- | :--- |
| **Email** | `string` | The validated email address. | `test@example.com` |
| **Status** | `string` | Verification status: `Valid`, `Invalid`, `Uncertain`, `Ignored`, or `Error`. | `Valid` |
| **Reason** | `string` | Details of the validation result (e.g., SMTP success, Disposable, Catch-All). | `Valid` |
| **Time** | `string` | Elapsed query duration. | `0.00s (Cached)` |
| **CatchAll** | `string` | Whether the domain accepts all emails (`Yes`, `No`, or empty). | `No` |
| **Disposable**| `boolean`| `true` if the domain is a temporary/burner provider. | `false` |
| **Role** | `boolean`| `true` if it is a department/functional account (e.g., info@). | `false` |
| **FreeEmail** | `boolean`| `true` if the domain is a free provider (Gmail/Yahoo). | `true` |
| **MXRecord** | `string` | The hostnames of the resolved mail exchanger servers. | `mx.example.com` |
| **Error** | `string` | Network or authorization error details if any occurred. | `""` |

# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "leads": """test@example.com

## CLI example

```bash
echo '{
  "leads": "test@example.com\\nhello@domain.com"
}' |
apify call thecfmarketing/bulk-email-verifier --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,thecfmarketing/bulk-email-verifier"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
