## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Bulk Email Validator

Bulk Email Validator is a NexGenData tool on Apify that returns validation results with syntax, MX, disposable and role-account checks from live DNS and mail-server checks.

Validate and clean email lists at scale — syntax, MX, disposable and role-account checks in one pass.

> You supply the addresses; the Actor validates them. Use it in line with applicable outreach and privacy law.

### 📊 Sample Output

![3 real rows delivered by Bulk Email Validator — Verify & Clean Lists API — run pMjYbZhnvamntGNeB on build 0.0.23](https://api.apify.com/v2/key-value-stores/8gLgXMBveEI1tTz1z/records/email-validator-sample)

| `email` | `status` | `isValid` | `domain` | `localPart` | `normalized` |
|---|---|---|---|---|---|
| \[email on record] | valid | True | stripe.com | support | \[email on record] |
| \[email on record] | valid | True | github.com | info | \[email on record] |
| \[email on record] | valid | True | mailinator.com | someone | \[email on record] |

Real rows from run `pMjYbZhnvamntGNeB` on build 0.0.23 (2026-09-25), unedited apart from masked emails/phones and shortened long text; fields the source does not publish are empty.

### ⚙️ Sample inputs

This is the Store example input — the same input Apify's automated check runs — so it is proven to return rows on the current build. Paste it into the input form, or send it through the API, CLI or a schedule:

```json
{
  "emails": [
    "jeff@amazon.com"
  ]
}
```

### 🔧 Input reference

| Field | Type | Default | What it does |
|---|---|---|---|
| `emails` | array of string | `["support@stripe.com", "info@github.com", "someone@mailinat…` | Email addresses to validate. Accepts either a JSON array (recommended) or a string with one email per line / comma-separated. Each address returned as a row is billed once. |
| `singleEmail` | string | `""` | Convenience field to validate a single email address |

### 🧾 JSON sample record

One real record from run `pMjYbZhnvamntGNeB` (emails/phones masked, long text shortened):

```json
{
  "email": "[email on record]",
  "status": "valid",
  "isValid": true,
  "valid": true,
  "syntaxValid": true,
  "mxValid": true,
  "hasMx": true,
  "domain": "stripe.com",
  "localPart": "support",
  "normalized": "[email on record]",
  "isDisposable": false,
  "disposable": false,
  "isFreeProvider": false,
  "isRoleAccount": true,
  "roleAccount": true,
  "deliverable": true,
  "mxRecords": [
    {
      "priority": 10,
      "server": "aspmx.l.google.com"
    },
    {
      "priority": 20,
      "server": "alt2.aspmx.l.google.com"
    },
    {
      "priority": 20,
      "server": "alt1.aspmx.l.google.com"
    },
    {
      "priority": 30,
      "server": "aspmx2.googlemail.com"
    },
    {
      "priority": 30,
      "server": "aspmx3.googlemail.com"
    }
  ]
}
```

### 💰 Pricing

| Event | Price (USD) | When it is charged |
|---|---|---|
| Actor Start (`apify-actor-start`) | $5e-05 | Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event). |
| Email validation (`apify-default-dataset-item`) | $0.05 | Charged per email address validated: checks syntax, MX records and disposable domains. Does not open an SMTP connection to the mailbox. |

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.

### 📊 What you get

Clean JSON, one record per email validated:

- `email` / `normalized` — the address, lower-cased and trimmed
- `status` — `valid` or `invalid`
- `isValid` / `valid` — the domain publishes MX records
- `syntaxValid` — RFC-shaped address
- `mxValid` / `hasMx` — MX lookup result
- `mxRecords` — up to 5 `{priority, server}` entries
- `domain` / `localPart`
- `isDisposable` / `disposable` — throwaway-mailbox domain
- `isFreeProvider` — consumer webmail domain
- `isRoleAccount` / `roleAccount` — generic mailbox (info@, sales@, support@ …)
- `deliverable` — syntax OK **and** MX present **and** not disposable
- `reason` — why an address was rejected (`invalid_syntax`, `nxdomain`, `no_mx_records`)

**Scope (honest):** validation is syntax + live DNS/MX + list checks. **No SMTP mailbox
probe is performed** — `deliverable` means the domain can accept mail, not that the
individual mailbox exists. Addresses whose DNS never answers are skipped and **not billed**;
if DNS is unreachable for every domain the run fails rather than returning filler rows.

**Pricing:** $0.050 per email validated (Pay-Per-Event) — about **20 emails per $1**.
Only delivered rows are charged.

### 🤖 Use with AI agents

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).
