Stop Fighting Email Authentication. Ship It.
PowerDMARC gives you hosted DNS records, real-time reporting, and a full REST API, so you can deploy a compliant DMARC infrastructure in days, not months.
Google, Yahoo, and Microsoft now require DMARC for bulk senders, making email authentication a business requirement rather than a security nice-to-have.
When attackers spoof your domain, users lose trust, deliverability suffers, and legitimate messages may never reach inboxes. Yet developers are often expected to solve these problems while managing infrastructure, applications, and security priorities.
PowerDMARC removes the complexity so you can deploy email authentication correctly and move on to building your product
A single misconfigured SPF record with one extra space, or one “all” mechanism in the wrong place, can break email for your entire domain. There's no staging environment for DNS.
Parsing, normalising, and storing RUA reports across hundreds of domains is a multi-sprint project before you've written a single alert rule.
Moving to p=reject before you've identified every legitimate sending source from your CRM, your transactional provider, to your billing system, means rejecting real mail. The only safe path to enforcement is complete coverage first.
PowerDMARC handles the implementation layer so you can focus on your product.
PowerDMARC offers two programmatic access modes depending on how your team works.
Full REST API covering record management, report retrieval, domain monitoring, and multi-tenant organization management. The right choice for SIEM pipelines, CI/CD hooks, internal dashboards, and any automation script.
If your team uses AI coding tools, the PowerDMARC MCP (Model Context Protocol) server lets you query DMARC data, manage records, and investigate authentication failures directly from your editor, without switching context to a dashboard or writing one-off scripts.
Managing DMARC for 50+ client domains manually doesn't scale. With the API, you can provision new domains, push record updates, and retrieve per-org reporting data programmatically, all under a single API key with org-scoped access control.
Feed authentication failures and DNS change events directly into Splunk, Microsoft Sentinel, or any SIEM that accepts webhook or REST input. Correlate DMARC failure spikes with other security events to detect active spoofing campaigns.
Use the API to validate DNS record state as part of your deployment pipeline. Before a domain goes live, assert that DMARC, SPF, and DKIM are correctly configured. Catch misconfigurations early.
For teams using Claude Code, Cursor, or Copilot, the MCP server removes the context-switching tax. Instead of opening a dashboard mid-incident, query PowerDMARC directly from your editor in plain language.
Most teams don’t need another infrastructure project. They need email authentication to work correctly.
Add your domain and verify ownership.
PowerDMARC generates and manages the required records for DMARC, SPF, DKIM, BIMI, and MTA-STS.
View authentication activity across all sending sources from a centralized dashboard.
Move toward quarantine and reject policies with confidence backed by real reporting data.
"The API made it possible for us to integrate DMARC management directly into our client onboarding workflow. What would have taken us months to build in-house was running in production within a week."
"Simple but powerful. The reporting API is the part I didn't expect to be this clean, structured JSON responses meant we could pipe data straight into our dashboard without any transformation layer."
"The dual strengths here are security depth and simplicity of setup. We had multi-domain monitoring running for our clients in a single afternoon."
