Domain Health Analyzer

Achieving optimal email security today is more than just implementing DMARC. To truly secure your domain and reputation, you need full visibility into how your authentication protocols are performing — and that’s where PowerDMARC’s Domain Health feature comes in.

This advanced diagnostic tool delivers a comprehensive analysis of your domain's email security posture, identifies misconfigurations, and offers actionable solutions to help you reach maximum protection and enforcement.

Key Takeaways 

1. All-in-One Check: Instantly assess DMARC, SPF, DKIM, BIMI, MTA-STS, and TLS-RPT.
2. Real-Time Scoring: Get a live domain security grade (e.g., A+, B, D).
3. Actionable Insights: See what’s broken, why, and how to fix it.
4. Quick Fixes: Jump directly to hosted tools to publish or edit records.
5. Misconfig Alerting: Flags issues like too many SPF lookups or missing DKIM.
6. Step-by-Step Guidance: Clear instructions and contextual help for every error.
7. Compliance Ready: Stay aligned with email security standards and best practices.

What is the Domain Health Feature?

Domain Health provides a real-time, detailed health check of all major email authentication protocols for a selected domain, including:

• DMARC 
• SPF 
• DKIM 
• BIMI 
• MTA-STS 
• TLS-RPT 

It doesn’t just highlight what’s working and what isn’t — it explains why and how to fix it with guided steps and seamless integration into PowerDMARC’s hosted tools.

Key Capabilities

PowerDMARC's Domain Health offers several key capabilities designed to streamline and enhance your email authentication journey. At its core, it performs a deep diagnosis of your domain's DNS records, identifying missing or invalid configurations, incomplete policy enforcement, and gaps in the above protocol implementations. These checks are then distilled into a dynamic, real-time security score (e.g., D+, A+, etc.),allowing you to instantly assess your domain's overall security posture.

For each issue uncovered, the tool provides a clear explanation, a suggested solution, and a direct link to the relevant hosted configuration page—whether it's fixing SPF lookups or publishing a TLS-RPT record. Moreover, the Domain Health interface is tightly integrated with PowerDMARC’s hosted services, so users can configure and validate records with a simple click, all without leaving the platform.

Steps to Use the Domain Health Feature

Log in to PowerDMARC Dashboard
Navigate to the Domain Health section from the left panel.

Select Your Domain
Use the dropdown menu to pick the domain you wish to analyze. Domain Health will instantly begin the health check process.

Review the Summary View
You'll see:

• Your domain’s current security score
• A checklist of the six main protocols with their status: ✅ Valid, ❌ Invalid, or ⚠️ Not Found
• Current DMARC policy status (e.g., p=none, quarantine, reject)

Explore Misconfigurations and Fixes
The dashboard breaks down:

• Errors (e.g., "SPF is invalid due to more than 10 DNS lookups")
• Tailored solutions (e.g., "Use PowerSPF to flatten your SPF record")

Take Action
 

Under the "Actions Needed" section, click on a recommendation (e.g., “Publish TLS-RPT Record”). This redirects you to the appropriate hosted configuration tool.

Example Use Case – SPF exceeding the RFC standard for 10 DNS lookup limit

Imagine that your domain's SPF record is invalid because it exceeds the standard 10 DNS lookup limit — a common issue that many organizations face. With Domain Health, this misconfiguration is promptly flagged, and the reason behind the error is clearly explained. The system then recommends a fix using PowerSPF, PowerDMARC’s automatic SPF flattening tool, which can generate an optimized, compliant SPF record. 

From the dashboard, you’re guided via a direct link to the PowerSPF configuration page, where you can instantly regenerate a valid record. Once you publish the new SPF record in your DNS and return to the Domain Health check, you’ll see your SPF status updated to valid, and your overall domain security score will reflect the improvement.

Why Domain Health Matters

Maintaining a high Domain Health score ensures:

• Better protection against spoofing and phishing
• Higher email deliverability
• Alignment with industry standards and compliance
• Enhanced brand trust with BIMI and DMARC enforcement
