# Check SPF, DMARC and DKIM for a list of domains

**Use case:** 

Paste up to 1,000 domains and get each one's SPF record and issues, DMARC policy, common DKIM selectors found, mail provider and an A–F email-authentication grade. One row per domain, export to CSV or Sheets.

## Input

```json
{
  "domains": [
    "apify.com",
    "github.com",
    "mailchimp.com",
    "example.com"
  ],

  "checkDkim": true,
  "checkRobots": true,
  "timeoutSecs": 15,
  "maxConcurrency": 5,
  "dnsResolver": "doh"
}
```

## How it works

### 1. Sign up on Apify or log in

The Website & Email Domain Checker: SSL, DNS, SPF, DMARC, DKIM Actor is ready to run with the inputs already set for "Check SPF, DMARC and DKIM for a list of domains". [Sign up or log in](https://console.apify.com/create-task-from-example/LcdAYeOFl63RxcvOf) and you'll land in Apify Console with a copy of this exact task.

### 2. Start the "Check SPF, DMARC and DKIM for a list of domains" task

The Website & Email Domain Checker: SSL, DNS, SPF, DMARC, DKIM Actor will start running based on the input automatically. You can also change all the input fields, like domains or urls, max domains, and more, to match your specific use case.

### 3. Receive the "Check SPF, DMARC and DKIM for a list of domains" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as domain, site up, HTTP status, and more.

### 4. Integrate into your workflow

The final output is delivered in JSON, CSV, or Excel format, ready to be plugged into your workflow. You can also [run the "Check SPF, DMARC and DKIM for a list of domains" task via API](https://apify.com/damodaran_dhanuauraman/website-email-domain-checker.md).

## FAQ

### What does the SPF/DMARC check return?

The bulk SPF, DMARC and DKIM check returns each domain's SPF qualifier and lookup count, DMARC policy and pct, DKIM selectors found among 19 common ones, the mail provider and an A–F grade.

### Can it find every DKIM key?

No. DKIM selectors can't be listed from DNS, so the domain checker probes 19 common selectors (Google, Microsoft, Mailchimp and others). A missing DKIM result means none of those selectors answered, not that DKIM is absent.

### How much does the domain check cost?

The Website & Email Domain Checker charges $0.008 per valid domain checked. Invalid or non-resolving domains are free, and a run stops at your spend limit.

### How do I run this check on a schedule or via API?

Save the Website & Email Domain Checker task to your account, then add a weekly schedule in Apify Console, or call the run-sync-get-dataset-items API endpoint from n8n, Make, Zapier or Clay.

## About this Actor

This example demonstrates how to use [Website & Email Domain Checker: SSL, DNS, SPF, DMARC, DKIM](https://apify.com/damodaran_dhanuauraman/website-email-domain-checker.md) with a specific input configuration.

## How to integrate an Actor?

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

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/damodaran_dhanuauraman/website-email-domain-checker.md

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`).
