# DMARC Checker (`onescales/dmarc-checker`) Actor Simple DMARC record lookup tool. Check email security configuration for multiple domains in a single run. - **URL**: https://apify.com/onescales/dmarc-checker.md - **Developed by:** [One Scales](https://apify.com/onescales) (community) - **Categories:** Developer tools, Automation, SEO tools - **Features:** Limited permissions - **Stats:** 21 total users, 0 monthly users, 100.0% runs succeeded, 1 bookmarks - **User rating**: 5.00 out of 5 stars ## Pricing from $1.00 / 1,000 results This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

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 ## DMARC Checker Bulk DMARC record lookup tool. Check email security configuration for multiple domains in a single run. [![Watch the video](https://img.youtube.com/vi/d0xvRnLFA7M/maxresdefault.jpg)](https://www.youtube.com/watch?v=d0xvRnLFA7M) ### Description DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps protect domains from unauthorized use like phishing and spoofing. This tool allows you to quickly verify DMARC records for one or thousands of domains at once. Perfect for: - **Agencies** auditing client email security - **IT teams** checking domain portfolios - **Security researchers** bulk-scanning domains - **Sales teams** qualifying leads by tech maturity ### Features - **Bulk Processing** — Check unlimited domains in a single run - **Instant Results** — Get DMARC status, policy, and reporting configuration for each domain - **Export Ready** — Download results as JSON, CSV, or Excel - **Detailed Output** — See the full raw DMARC record for each domain - **Validation** — Automatically detects valid, invalid, and missing DMARC records ### How to Use 1. Enter your domain name(s) (one per line or use bulk edit) 2. Click **Start** 3. View results in the Output tab or export to your preferred format No technical setup required. Just add your domains and run. ### Input | Field | Description | |-------|-------------| | **Domains** | List of domain names to check. Enter bare domain names only (e.g., `example.com`). Do not include `http://` or `https://`. | ### Output Each domain returns one row with the following fields: | Field | Description | Example Values | |-------|-------------|----------------| | `domain` | The domain checked | `example.com` | | `recordStatus` | Whether a valid DMARC record exists | `Valid` / `Invalid` / `Not Found` | | `domainPolicy` | The DMARC policy (p= tag) | `none` / `quarantine` / `reject` | | `reportingEnabled` | Whether reporting is configured (rua/ruf tags) | `true` / `false` | | `rawRecord` | The full DMARC TXT record | `v=DMARC1; p=reject; rua=mailto:...` | #### Record Status Meanings - **Valid** — DMARC record exists with proper version (v=DMARC1) and policy (p=) tags - **Invalid** — Record exists but is malformed (missing version or policy) - **Not Found** — No DMARC record found at `_dmarc.{domain}` ### Contact / Support Questions or need additional features?

Clients without OAuth support can send an `Authorization: Bearer ` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations). ## OpenAPI specification Download the OpenAPI definition: https://api.apify.com/v2/actors/cxOxG6VsLqT140DBn/builds/GklKlUuUbEGgove1b/openapi.json
