## Pricing

from $0.50 / 1,000 email verifieds

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/docs.md):

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

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

## Bulk Email Verifier — $0.50 / 1,000 emails

Clean your email lists before you send. Paste up to 100,000 addresses (or point the actor at any other actor's results) and get one clean record per email: a **valid / risky / invalid / unknown** status, a **0–100 quality score**, the reason behind the verdict, and a **did-you-mean fix** for typo'd addresses — at **$0.50 per 1,000 emails**, with **malformed rows checked free**.

Lower bounce rates protect your sender reputation, keep you out of spam folders, and stop you paying your email platform for dead contacts.

### What we check — and what we don't

**We check:** syntax and normalization · typo detection with did-you-mean fixes · disposable/temp-mail domains · role-based and no-reply inboxes · free-provider detection · **live DNS**: MX mail-server records, null-MX (domains that refuse all mail), A-record fallback, SPF and DMARC authentication health · a 0–100 score built from all of it.

**We don't (currently):** a live SMTP mailbox probe — the "does john@ exist on this server" handshake. The `smtp` field in every record honestly reports `unknown`. Cloud platforms block the network port that check requires, which affects **every** verification actor on Apify, regardless of what their listings claim — most quietly return "unknown" or "catch_all" dressed up in a score. We say it plainly instead, and we cap DNS-evidence scores at 85: scores of 86–100 are reserved for SMTP-confirmed mailboxes, so a score from this actor is never overstated.

### What you get

One record per unique email address (duplicates are removed and never double-charged):

```json
{
  "email": "jane@gmial.com",
  "normalizedEmail": "jane@gmial.com",
  "domain": "gmial.com",
  "status": "invalid",
  "subStatus": "typo_domain",
  "score": 0,
  "didYouMean": "jane@gmail.com",
  "syntaxValid": true,
  "mxFound": false,
  "smtp": "unknown",
  "catchAll": null,
  "disposable": false,
  "roleBased": false,
  "freeProvider": false,
  "hasTag": false,
  "mxRecords": [],
  "spf": null,
  "dmarc": null
}
````

| Field | Meaning |
|---|---|
| `status` | `valid` — safe to send · `risky` — deliverable but risky (shared inbox, catch-all, throwaway) · `invalid` — do not send · `unknown` — could not be determined |
| `subStatus` | The specific reason: `mx_verified`, `no_mx_record`, `typo_domain`, `disposable`, `domain_rejects_mail`, `bad_syntax`, … |
| `score` | 0–100 deliverability quality score — sort by it, pick your own cut-off |
| `didYouMean` | Suggested fix for mistyped providers (`gmial.com` → `gmail.com`) |
| `mxFound` / `mxRecords` | Whether the domain runs mail servers, and which ones |
| `disposable` | Throwaway/temp-mail domain (10-minute inboxes, mailinator, …) |
| `roleBased` | Shared inbox (`info@`, `support@`, `noreply@`, …) — risky for outreach |
| `freeProvider` | Consumer provider (Gmail, Yahoo, Outlook, …) rather than a company mailbox |
| `hasTag` | Address contains a `+tag` (often signup filters) |
| `spf` / `dmarc` | Domain email-authentication health — a spam-filter signal |
| `smtp` / `catchAll` | Mailbox-level SMTP probe result — currently always `unknown`/`null`, see "What we check" above |

Export as CSV/Excel with one click, or append `?format=csv` / `?format=xlsx` to the dataset URL.

### Statuses you can act on

- **valid** → keep. The domain provably receives mail and the address shape is good.
- **risky** → send with care: shared `info@` inboxes, catch-all domains, disposable services.
- **invalid** → delete. Bad syntax, mistyped provider, no mail server, or a domain that refuses all mail (null MX).
- **unknown** → the evidence was inconclusive (DNS timeout, bare-A-record domain). Not charged less — but honestly labeled instead of guessed.

### Verify results from other actors — zero copy-paste

Under **Advanced**, paste the dataset ID of any finished run and the verifier pulls addresses automatically:

- [Website Contact Scraper](https://apify.com/mamiestech/website-contact-scraper) → set **Email field name** to `emails`
- Google Maps scraper runs with email enrichment → leave it as `email`

Scrape → find contacts → verify, all inside Apify.

### Pricing — no surprises

- **$0.50 per 1,000 verified emails** ($0.0005 each), pay-per-event. No subscription tiers, no platform-usage add-ons.
- **Free:** malformed rows (`not-an-email`), duplicate rows, and every re-run of the same unique address in one run.
- Set a **maximum cost** on any run (`maxTotalChargeUsd`) — the run stops cleanly at your cap and you keep everything delivered up to it.

### How it works

Each address goes through: syntax & normalization → typo detection → disposable & role checks → live DNS (MX records, RFC 7505 null-MX, A-record fallback, SPF/DMARC) → scoring. The `smtp` and `catchAll` fields are reserved for our upcoming SMTP relay tier and report `unknown`/`null` until then — see "What we check — and what we don't" above.

### FAQ

**Is this GDPR-safe?** The actor never sends email and never stores your list beyond the run's dataset, which you control and can delete.

**What's a catch-all domain?** One that accepts mail for *any* address — a "yes" there can't prove your specific contact exists, so it's `risky`.

**Why is `info@` risky and not invalid?** It usually delivers — but shared inboxes convert poorly and complain often, so outreach tools treat them as risky.

**How many emails per run?** Up to 100,000. Need more? Split the list or run several inputs in parallel.

# Actor input Schema

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

One email address per line. Duplicates are removed automatically — you're charged once per unique address, and malformed rows are checked for free.

## `datasetId` (type: `string`):

Dataset ID (or username/dataset-name) of any actor run whose results contain email addresses. Verified emails are ADDED to any pasted list above.

## `emailField` (type: `string`):

Name of the dataset field holding the email address. The field may contain a single address or a list — use "emails" for Website Contact Scraper output.

## Actor input object example

```json
{
  "emails": [
    "john.doe@gmail.com",
    "support@apify.com",
    "email@example.com"
  ],
  "emailField": "email"
}
```

# Actor output Schema

## `verifiedEmails` (type: `string`):

One record per unique email — status (valid / risky / invalid / unknown), sub-status reason, 0-100 quality score, did-you-mean typo fix, and per-check flags (syntax, MX, SMTP, catch-all, disposable, role-based, free provider, +tag, SPF, DMARC). Append ?format=csv or ?format=xlsx to the URL for spreadsheet exports.
