# Find Domains With No DMARC or Weak Email Security

**Use case:** 

Only domains that grade under 70 come out: no DMARC or DMARC at p=none, missing or broken SPF, no DKIM key found. Domains that pass are checked but left out and not charged. For MSP and IT security prospecting: replace the examples with your prospect list.

## Input

```json
{
  "domains": [

## About this Actor

This example demonstrates how to use [Bulk DMARC, SPF & DKIM Checker + Email Provider & SaaS Finder](https://apify.com/jtpalms/email-security-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/jtpalms/email-security-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`).
