# Find which email provider companies use

**Use case:** 

Reads the MX records of each company domain and names the mail provider (Google Workspace, Microsoft 365, Zoho, OVHcloud...), with SPF and DMARC status. Use it to segment a B2B list by email stack.

## Input

```json
{
  "domains": [
    "stripe.com",
    "airbnb.com",
    "spotify.com",
    "doctolib.fr",
    "decathlon.fr"
  ],
  "includeDns": true,
  "includeEmailSecurity": true,
  "includeSsl": false
}
```

## Output

```json
{
  "domain": {
    "label": "Domain"
  },
  "registered": {
    "label": "Registered",
    "format": "boolean"
  },
  "registrar": {
    "label": "Registrar"
  },
  "createdAt": {
    "label": "Created",
    "format": "date"
  },
  "expiresAt": {
    "label": "Expires",
    "format": "date"
  },
  "daysToExpiry": {
    "label": "Days to expiry",
    "format": "number"
  },
  "mailProvider": {
    "label": "Mail provider"
  },
  "dmarcPolicy": {
    "label": "DMARC policy"
  },
  "ssl.daysToExpiry": {
    "label": "SSL days left",
    "format": "number"
  },
  "errors": {
    "label": "Errors",
    "format": "array"
  }
}
```

## About this Actor

This example demonstrates how to use [WHOIS & DNS Domain Lookup (RDAP) - SPF, DMARC, SSL](https://apify.com/propped_cloak/whois-dns-domain-lookup.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/propped_cloak/whois-dns-domain-lookup.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`).
