New Free Tools Now Available on DMARCeye

Email authentication should not require guesswork or a collection of disconnected online tools. Yet for many teams, configuring DMARC, SPF, DKIM, or BIMI still involves trial and error, DNS lookups, and uncertainty about whether records are correctly published.

To reduce that friction, we expanded the DMARCeye Free Tools section of our website and app with a set of practical utilities designed to help you validate, configure, and troubleshoot your domain records with confidence.

These tools are built for real-world workflows. Whether you are publishing your first DMARC record, investigating alignment failures, or preparing for enforcement, they give you immediate clarity without requiring an account.

Email Authentication Is Critical, but Often Misconfigured

DMARC, SPF, DKIM, and BIMI are now baseline requirements for domain protection and inbox placement. Mailbox providers expect proper authentication. Security teams rely on it to prevent spoofing. Marketing teams depend on it for deliverability.

At the same time, these standards are DNS-based and highly syntax-sensitive. A missing tag, an invalid include mechanism, or a selector typo can cause:

• Unexpected DMARC failures
• Alignment issues between SPF and DKIM
• Reduced inbox placement
• Increased spoofing risk

If you are still working through implementation fundamentals, start with our Complete DMARC Implementation Guide. If you are troubleshooting live issues, see How to Troubleshoot and Fix DMARC Issues.

The new Free Tools section complements those guides by providing instant validation and configuration support.

DMARC Record Configurator

The DMARC Record Configurator helps you generate a properly formatted DMARC record step by step.

Instead of manually assembling tags such as p, rua, ruf, or pct, the configurator guides you through the setup and ensures correct formatting. It also encourages best-practice defaults based on your enforcement stage.

If you are currently operating at p=none and planning your move toward enforcement, this tool helps structure that transition safely.

DNS Checker

The DNS Checker allows you to quickly inspect published records and confirm what is actually visible in DNS.

This is especially useful after publishing new records, updating sending infrastructure, or investigating authentication failures. Confirming DNS propagation and record visibility early prevents unnecessary troubleshooting cycles.

SPF Checker

The SPF Checker validates your SPF record and identifies common structural issues such as syntax errors or excessive DNS lookups.

SPF failures often surface indirectly through DMARC alignment problems. If you need a refresher on how these standards interact, review DMARC vs DKIM vs SPF.

By validating SPF properly, you reduce unauthorized sending and improve authentication stability.

DKIM Checker

The DKIM Checker verifies that your DKIM public key is correctly published and accessible using the specified selector.

Because DKIM plays a key role in DMARC alignment, even a small selector error can cause persistent failures. This tool helps confirm that your signing configuration is correctly exposed in DNS.

BIMI Checker

The BIMI Checker helps you confirm that your BIMI record is correctly configured and accessible.

BIMI requires precise DNS setup and a properly formatted logo file. Validation removes ambiguity and ensures your configuration is ready for mailbox provider evaluation.

Free on the Website and Integrated in the App

All of these tools are available publicly at dmarceye.com/free-tools, as well as inside our app. You can use them on our website without creating an account.

For DMARCeye users, the same utilities are fully integrated into the platform. This means you can validate records, investigate authentication issues, and monitor your domains in one environment instead of switching between multiple external services.

Reducing Friction in Domain Security

Across thousands of monitored domains, we consistently see the same recurring issues:

• Incorrect DMARC syntax
• SPF records exceeding lookup limits
• Misaligned DKIM selectors
• Unclear enforcement transitions

These are not advanced security failures. They are configuration friction points. Our free tools are designed to eliminate that friction and provide immediate technical clarity.

Why DMARCeye

Standalone checkers are helpful. Continuous visibility is essential.

DMARCeye turns raw DMARC aggregate reports into actionable insight by providing:

• Ongoing visibility into who sends on your behalf
• Early detection of new or suspicious sending sources
• Guided transitions from monitoring to enforcement
• Clear correlation between authentication failures and infrastructure
• Integrated DNS utilities alongside monitoring data
• MCP Server functionality, which enables you to connect your DMARC data to chat assistants like ChatGPT.

The Free Tools help you validate individual records. DMARCeye helps you manage your entire authentication posture over time.

If you want continuous clarity instead of occasional checks, start with a free DMARCeye trial today.
