## 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

## Email Deliverability Checker: Bulk SPF, DKIM & DMARC (DNS Security)

**Email deliverability** audit for any domain list: check whether mail will land in the inbox or get spoofed. For each domain you get a **0–100 score**, **A–F grade**, plain-English issues, plus parsed **SPF, DKIM, DMARC, MX, MTA-STS, BIMI, CAA and DNSSEC** records.

**$1 per 1,000 domains** ($0.001 each). Invalid / NXDOMAIN rows are free.

### Why teams use it

- **Inbox placement:** catch SPF >10 DNS lookups, missing DKIM, or DMARC stuck at `p=none` before Gmail/Yahoo bulk-sender rules bite
- **Spoofing risk:** grade your domains, subsidiaries and vendors
- **Sales / MSP leads:** find weak email auth and back the pitch with an issue list
- **Stack intel:** detect Google Workspace / M365, ESP (SendGrid, Mailchimp…) and SaaS verification TXT records

### What it checks

| Check | You get |
|---|---|
| **SPF** | Record, `all` qualifier, recursive lookup count vs RFC 7208 limit of 10 |
| **DMARC** | `p` / `sp` / `pct` / `rua` / `ruf`, alignment |
| **DKIM** | ~40 common selectors + custom; key size (flags weak 1024-bit keys) |
| **MX** | Priority list + detected email provider |
| **MTA-STS / TLS-RPT / BIMI / CAA / DNSSEC** | Policy, reporting, brand logo, CA issuance, validation |

### Fast free-tier try

```json
{ "domains": ["apify.com", "github.com", "example.com"], "maxDomains": 3 }
```

### Example output

| Field | Example |
|---|---|
| `domain` | `apify.com` |
| `score` / `grade` | `92` / `A` |
| `spf.lookupCount` | `6` |
| `dmarc.policy` | `quarantine` |
| `mx.provider` | `Google Workspace` |
| `issues[]` | Human-readable findings |

### Pricing

**$0.001 per domain** audited + $0.00005 start. Failures are free. Cap with `maxDomains` or *Maximum cost per run*.

# Actor input Schema

## `domains` (type: `array`):

One per line. Domains (acme.com), URLs (https://www.acme.com/about) or email addresses (jane@acme.com) all work. Duplicates are removed.

## `domainsText` (type: `string`):

Optional: paste domains separated by new lines, spaces or commas (handy for large lists).

## `checkDkim` (type: `boolean`):

Look for DKIM keys (DKIM keys can only be found by selector name). Reports each key's type and size.

## `useCommonDkimSelectors` (type: `boolean`):

Try about 40 common selectors (Google Workspace, Microsoft 365, Mailchimp/Mandrill, SendGrid, Zoho, Proton, Fastmail, Mailjet, HubSpot, Amazon SES and others).

## `dkimSelectors` (type: `array`):

Your own selectors to check as well, e.g. 20230601 or mycompany1.

## `fetchMtaStsPolicy` (type: `boolean`):

When an \_mta-sts record exists, download https://mta-sts.<domain>/.well-known/mta-sts.txt to read the mode (enforce/testing/none).

## `stripWww` (type: `boolean`):

Check example.com when you enter www.example.com (email records live on the bare domain).

## `maxDomains` (type: `integer`):

Check at most this many domains (0 = all).

## Actor input object example

```json
{
  "domains": [
    "apify.com",
    "github.com",
    "example.com"
  ],
  "checkDkim": true,
  "useCommonDkimSelectors": true,
  "fetchMtaStsPolicy": true,
  "stripWww": true,
  "maxDomains": 3
}
```

## CLI example

```bash
echo '{
  "domains": [
    "apify.com",
    "github.com",
    "example.com"
  ],
  "maxDomains": 3
}' |
apify call globose_talent_mn9/dns-email-security-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,globose_talent_mn9/dns-email-security-checker"
        }
    }
}
```

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).
