# Email Validation — Verify Deliverability, Mailbox & Catch-All ✅ (`neuralverge/neuralverge-email-validation`) Actor

Validate an email address and get deliverability signals: a valid / invalid result, whether the mailbox exists, catch-all detection, the mail provider and a confidence level. One email per run.

## 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.

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

### Email Validation — Verify Deliverability, Mailbox & Catch-All ✅ No API Key

Validate any **email address** and get clear **deliverability signals** — a `valid` / `invalid`
result, whether the **mailbox actually exists**, **catch-all** detection, the **mail provider** and
a **confidence** level. Powered by the Neuralverge API. **No API key or account required.**

Ideal for cleaning lists before a send, cutting bounce rates, protecting sender reputation, and
validating signups, leads and CRM records.

### ✨ Why this Actor

- ✅ **Real deliverability verdict** — `valid` / `invalid` plus a plain-English message such as
  "Mailbox exists".
- 🪤 **Catch-all detection** — flags catch-all domains that accept anything, so you can weight the
  result accordingly.
- 🏷️ **Provider & confidence** — see which mail provider hosts the address and how confident the
  check is.
- 🔑 **No API key or account** — the check runs on the Neuralverge backend.
- ⚡ **Real-time & structured** — a fresh verdict each run, ready for a spreadsheet, CRM or AI
  pipeline.

### 🔧 How it works

1. **Provide an email address** — e.g. `steve@builder.io`.
2. **Run the Actor.** The validation happens on the Neuralverge backend.
3. **Get one dataset row per email** — the input email plus the structured `machine` verdict.
   Export to CSV, JSON or Excel, or pull it over the Apify API.

### Input

One email per run.

| Field | Type | Notes |
|---|---|---|
| `email` | string | The email address to validate. |

```json
{
  "email": "steve@builder.io"
}
````

### What you'll receive

Each dataset row has these top-level blocks:

- **`email`** — the address you submitted.
- **`machine`** — the structured verdict: `result` (`valid` / `invalid` / …), `message` (e.g.
  "Mailbox exists"), `isCatchAll` (whether the domain accepts any address), `provider` (the mail
  provider) and `confidence` (`high` / `medium` / `low`).

> **Read `isCatchAll` alongside `result`.** On a catch-all domain the server accepts every address,
> so a `valid` result is weaker evidence — treat `confidence` as a guide, not a guarantee.

#### Example output (real run)

A real dataset row for an email validation, shown **in full** — the structured **machine-readable
verdict** (`machine`). The `human` markdown summary is produced by the system but omitted from the
dataset.

```json
{
  "email": "steve@builder.io",
  "machine": {
    "email": "steve@builder.io",
    "result": "valid",
    "message": "Mailbox exists",
    "isCatchAll": false,
    "provider": "GOOGLE",
    "confidence": "medium"
  }
}
```

> Genuine output from a live run — the address is deliverable, the mailbox exists, and the domain is
> not catch-all.

### Pricing

Pay per validated email — **$0.001 per email** ($1 per 1,000) returned to the dataset.

| Event | Price |
|---|---|
| Actor start | Free |
| Verdict returned (per dataset row) | **$0.001** |

You're billed per verdict returned to the dataset. If the check errors out and returns nothing, you
are not charged. Pricing is on top of your Apify platform usage.

### Integrations & API

Results are stored in a standard Apify dataset — export as CSV, JSON, XML or Excel,
or fetch on demand through the [Apify API](https://docs.apify.com/api). The Actor
also plugs into Apify's integrations (Make, Zapier, n8n, webhooks) and can be called
from any [MCP](https://mcp.apify.com/) client.

### FAQ

**Do I need an account or API key?** No. The validation runs on the Neuralverge backend.

**What does `result` mean?** `valid` means the address looks deliverable and the mailbox was
resolved; `invalid` means it was not. Always read it together with `isCatchAll` and `confidence`.

**What is a catch-all domain?** A domain configured to accept mail for any address. On such domains
a `valid` result is less certain, because the server won't reject unknown mailboxes.

**Can I validate a whole list?** Run one email per run and collect the rows in the dataset, or drive
the Actor from Apify's integrations to process a list.
