## 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 — Deliverability Checker

ZeroBounce-style email validation API: verify any email address and get a **0–100 deliverability score** plus detailed diagnostics, without needing your own SMTP infrastructure.

### 🚀 Quick Start

1. Click **Try for free** (or Run) on this Actor
2. Paste your email list (one per line) into the **emails** field
3. Run — get a verdict for every address instantly

**No input?** The Actor runs a demo batch so you can see the output format immediately.

### 🔍 What it checks

| Check | Method |
|---|---|
| Format validation | RFC-style regex |
| Domain validity | **MX record lookup** (DNS) |
| Disposable email detection | 30+ known disposable domains (mailinator, 10minutemail…) |
| Free provider flag | Gmail, Yahoo, Outlook, Naver, Proton… (30+) |
| Spelling check | Detects `gmail.co` → `gmail.com` typos with suggestions |
| SMTP handshake *(optional)* | Live connect to MX host, `MAIL FROM`/`RCPT TO` |

### 📊 Output

Every email returns structured JSON:

```json
{
  "email": "john.doe@gmail.com",
  "status": "valid",
  "score": 95,
  "reason": "syntax_and_mx_valid",
  "domain": "gmail.com",
  "mxFound": true,
  "mxHosts": ["gmail-smtp-in.l.google.com"],
  "isDisposable": false,
  "isFreeProvider": true,
  "smtpCheck": "skipped",
  "spelling": {"typo": false, "suggestion": null}
}
```

Plus a run summary (total / valid / invalid / average score).

### 💡 Use cases

- **Marketing** — clean your lists before a campaign, cut bounce rates
- **Sales** — verify lead emails before outreach sequences
- **Data quality** — dedupe and validate CRM imports
- **Signup flows** — catch disposable addresses at registration
- **Email hygiene for agencies** — batch-verify client lists

### ⚙️ Technical notes

- Status values: `valid`, `invalid`, `unknown` (SMTP probe blocked)
- Score 0–100: syntax + MX + disposable + SMTP signals combined
- SMTP check is **off by default** — many servers block probes and it slows runs; enable only when you need the extra signal
- Public DNS only, no API keys needed

*Inspired by commercial email verification services (ZeroBounce, NeverBounce, Hunter).*

# Actor input Schema

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

List of email addresses to verify. Empty input runs a demo batch.

## `checkSmtp` (type: `boolean`):

Optionally perform a live SMTP handshake (slower, some servers block probes). Default off.

## Actor input object example

```json
{
  "emails": [
    "john.doe@gmail.com",
    "test@mailinator.com"
  ],
  "checkSmtp": false
}
```

# 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": [
        "john.doe@gmail.com",
        "test@mailinator.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("unrivaled_fortress/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);
});
