Get clarity on how our free tools help you implement and troubleshoot email security.
Why are free DMARC tools important?
Free DMARC tools, like generators and validators, are crucial for making email authentication accessible to everyone. They allow businesses of all sizes to start their DMARC journey, gain visibility into their email channels, and take the first step toward blocking phishing and spoofing attacks without an initial financial commitment.
What is an SPF record generator used for?
An SPF record generator helps you create a correctly formatted DNS record that lists all the authorized servers and services allowed to send email on behalf of your domain. This is a fundamental step in preventing spammers from using your domain for unauthorized emails.
How can a DKIM validator help me?
A DKIM validator checks if your DKIM DNS record is correctly published and configured. It verifies the public key that receiving mail servers use to check the cryptographic signature on your emails, ensuring that your messages haven't been tampered with in transit.
Are all these email security tools really free to use?
Yes, our entire suite of email security tools—including all generators, validators, and lookups—is completely free to use. They are designed to help you secure your domain. For advanced, automated monitoring and reporting, we offer our comprehensive Nullify (TODMARC) platform.
