Frequently Asked Questions
Your common questions about DMARC and our platform, answered.
What is DMARC monitoring and why do I need it?
DMARC monitoring provides visibility into who is sending email using your domain. You need it to identify unauthorized senders, block phishing attacks, prevent domain spoofing, and ensure your legitimate emails are delivered reliably, which is now a requirement for major inbox providers like Google and Yahoo.
How does Nullify (TODMARC) simplify DMARC enforcement?
Nullify (TODMARC) simplifies DMARC by providing clear, human-readable reports, guided setup wizards, and expert support. Our platform automates the analysis of complex DMARC data, helping you safely move from a monitoring policy (p=none) to a full enforcement policy (p=reject) without blocking legitimate email.
Which DMARC policy (none, quarantine, reject) should I start with?
You should always start with a 'p=none' policy. This allows you to monitor email traffic without affecting email delivery. Once you have identified and authenticated all legitimate sending sources using our platform, you can confidently move to 'p=quarantine' and then to the most secure policy, 'p=reject'.
Is DMARC difficult to set up with Nullify (TODMARC)?
No. Our platform is designed for simplicity. We provide a step-by-step guided process that makes DMARC setup straightforward, even for non-experts. Plus, our human support team is available to help you at every stage.
