# Bulk Email Validator: syntax, MX, disposable, role flags (`thoob/email-validator`) Actor

Validates a list of email addresses: practical RFC 5322 syntax, live domain mail-capability (MX/A over DNS-over-HTTPS), disposable-domain detection, and role-account flags. Honest scope: it checks the address and the domain, not the mailbox. Billed only per address checked.

## Pricing

$0.50 / 1,000 checked email addresses

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Email Validator

Clean a list of email addresses you already have. For each address the actor
checks practical RFC 5322 syntax, whether the domain can actually receive mail
(MX records, with an A/AAAA fallback per RFC 5321) over DNS-over-HTTPS, whether
the domain is a known disposable/temporary-mail provider, and whether the local
part is a role mailbox (`info@`, `support@`, ...) rather than a person.

This actor validates addresses you supply. It does not find, guess, or harvest
addresses.

### Honest scope

It verifies the address and its domain, not the individual mailbox. It does not
open an SMTP session or probe whether a specific inbox exists, so it will not
claim a precise deliverability percentage. What it returns is exact: the syntax
verdict and the domain's live mail records.

### Input

- **Email addresses**: one per line.
- **DNS resolver**: Cloudflare or Google (the other is the fallback).
- **Max checked addresses**: cap on billed rows (0 = no cap).

### Output

`email`, `normalized`, `localPart`, `domain`, `syntaxValid`, `hasMx`, `mxHost`,
`domainResolves`, `disposable`, `roleAccount`, `status`, plus provenance
(`sourceUrl` is the DoH MX query, `retrievedAt`, `confidence`, `dataSource`).

### Billing

Pay per address actually checked. Addresses that fail the syntax check before any
DNS work are written to the free `rejected` dataset and are not billed.

### Sample output

A real run checking a mixed list (deliverable, disposable, and bad addresses):

| email | syntax | MX | role | disposable | status |
| --- | --- | --- | --- | --- | --- |
| info@cloudflare.com | True | True | True | False | deliverable_domain |
| support@github.com | True | True | True | False | deliverable_domain |
| test@mailinator.com | True | True | False | True | disposable |
| x@guerrillamail.com | True | True | False | True | disposable |

Malformed addresses route to the free reject dataset. Each checked row carries a `sourceUrl` (the live MX lookup), for example `https://cloudflare-dns.com/dns-query?name=cloudflare.com&type=MX`.

# Actor input Schema

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

The addresses to validate, one per line. These are addresses you already have (your list, your signups); this actor checks them, it does not find or harvest new ones.
## `resolver` (type: `string`):

DNS-over-HTTPS resolver used for the MX/A check. The other is the automatic fallback.
## `maxEmails` (type: `integer`):

Cap on addresses checked and billed. 0 means no cap. The platform spend cap is honored regardless.

## Actor input object example

```json
{
  "emails": [
    "jane@google.com",
    "info@cloudflare.com",
    "test@mailinator.com",
    "bad@@nope"
  ],
  "resolver": "cloudflare",
  "maxEmails": 0
}
````

# Actor output Schema

## `results` (type: `string`):

One row per address checked.

# 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@google.com",
        "info@cloudflare.com",
        "test@mailinator.com",
        "bad@@nope"
    ]
};

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