## Pricing

from $8.00 / 1,000 verified email founds

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.

# README

### Email Finder + Verifier — Name & Domain → Deliverable Email

**You give:** a person's name and their company domain — e.g. `Patrick Collison` + `stripe.com`.
**You get:** their **verified, deliverable email address** — one confirmed mailbox, with a confidence score, marked **FOUND** or **NOT_FOUND**.
**You pay:** **only per verified email found — $0.008.** Not-found is **free**.

No LinkedIn, no scraping of protected sources. This is a deterministic **pattern engine** plus **live deliverability verification** — the two things that actually turn a name into an address you can send to.

---

#### Why "verified" is the whole point
Most email finders hand you `first.last@company.com` and call it a day. You send, it bounces, and your domain reputation takes the hit. Here, every `FOUND` address has been through:

> pattern generation → syntax → MX record → **live SMTP mailbox check** → catch-all detection → confidence score

Only an address that a real mail server **accepts**, that is **not catch-all**, at **confidence ≥ 0.80**, is returned as `FOUND`. Everything else is `NOT_FOUND` with a reason and a clearly-labelled `best_guess` — never a silent, billed guess.

#### How it works
1. **Normalize** the name (lowercase, strip accents/punctuation) and the domain (strip `https://`, `www.`, paths — full URLs are fine).
2. **Generate candidates** in priority order: `first.last`, `first`, `flast`, `firstlast`, `first_last`, `f.last`, `last.first`, `lastf`, `first-last`, `last` — each `@domain`.
3. **Optional site scan** (`siteScan`, on by default): fetch the company's homepage, `/contact` and `/about` and promote any **published** address that matches a candidate to the front — those are real, not guesses.
4. **Local pre-filter (free):** drop bad-syntax candidates and, if the domain has **no MX record at all**, return `NOT_FOUND` immediately — with **no charge**.
5. **One batched deliverability check:** survivors go to a proven Apify Store validator with real SMTP egress, in a single call per run.
6. **Pick the winner:** the first deliverable, non-catch-all, confident address becomes `FOUND`. **You are charged only for FOUND.**

#### What each row gives you
| Column | Meaning |
|---|---|
| `action` | **FOUND** (verified deliverable) or **NOT_FOUND** (with reason) |
| `firstName` / `lastName` | The person you asked about |
| `domain` | The normalized company domain |
| `verified_email` | The deliverable address — **only on FOUND** |
| `pattern` | Which pattern won (`first.last`, `flast`, `published`, …) |
| `confidence` | 0–1 deliverability confidence |
| `source` | `pattern` (generated) or `published` (found on the company site) |
| `candidates_checked` | How many addresses were tested |
| `reason` | On NOT_FOUND: `catch_all_domain` / `all_rejected` / `no_mx` / `verifier_unavailable` |
| `best_guess` / `best_guess_confidence` | On NOT_FOUND: the most-likely address, **clearly not verified** |

#### Honest by design
- We **never invent** an address and label it verified. `FOUND` means a live mail server accepted that specific mailbox.
- **Catch-all domains** — which accept everything and confirm nothing — are returned as `NOT_FOUND` (`catch_all_domain`) and **are not charged**. We will not bill you for a domain that cannot actually confirm the person.
- If the verifier is unavailable, we degrade to `NOT_FOUND` (`verifier_unavailable`) — never a fabricated "deliverable" result, never a charge.
- A `best_guess` is always presented as a guess, never as a verified address.

#### For agents & automation
Call it via the Apify **API** or **MCP**. Pass an array of `{firstName, lastName, domain}` (or `{fullName, domain}`) and get back deduped, verified rows — ideal as a step in an enrichment pipeline. **Schedule** it for recurring enrichment of a lead list into your CRM or sequencer. You pay only for the addresses that are actually deliverable.

*Input: `people` (array of name + domain). Optional: `maxCandidatesPerPerson` (cost cap), `siteScan`, `verifierActorId`, `requestTimeoutSecs`.*

# Actor input Schema

## `people` (type: `array`):

Each item: {"firstName":"...","lastName":"...","domain":"..."}. You may pass "fullName" instead of first/last, and a full URL instead of a bare domain — both are normalized.
## `maxCandidatesPerPerson` (type: `integer`):

Upper bound on how many candidate addresses are sent to the verifier per person (caps cost).
## `siteScan` (type: `boolean`):

Fetch homepage, /contact and /about and promote any published address that matches a candidate (real, not a guess).
## `verifierActorId` (type: `string`):

Apify Store validator used for the live SMTP deliverability check. Default is a proven high-volume validator.
## `requestTimeoutSecs` (type: `integer`):

How long to wait for each company web page during the optional site scan.

  "people": [
    {
