# Bulk SPF and DMARC Checker

**Use case:** 

Check SPF and DMARC for a whole list of domains in one run. For every domain you get the SPF record and its all-mechanism, the DMARC policy (including a policy inherited from the parent domain), the e-mail provider behind the MX records and the DNS provider, plus a security grade with the exact record to publish when something is missing. Pay per domain.

## Input

```json
{
  "urls": [
    "github.com",
    "stripe.com",
    "shopify.com",
    "notion.so",
    "wordpress.org"
  ],
  "includeSecurity": true,
  "includeDns": true,
  "maxConcurrency": 10,
  "requestTimeoutSecs": 20
}
```

## Output

```json
{
  "url": {
    "label": "Website",
    "format": "string"
  },
  "dns.domain": {
    "label": "Domain",
    "format": "string"
  },
  "dns.emailProvider": {

    "format": "string"
  },

    "format": "array"
  },
  "dns.dnsProvider": {

  },
  "dns.nameservers": {

## About this Actor

This example demonstrates how to use [Tech Stack Detector: Wappalyzer & BuiltWith Alternative](https://apify.com/hxckya/tech-stack-security-check.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/hxckya/tech-stack-security-check.md) to learn more, explore other use cases, and run it yourself.


## 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.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
