DuoCircle's DMARC Monitoring gives you real-time visibility into who's sending email on your behalf — so you can block imposters, protect recipients, and keep your domain's reputation intact.
DMARC Monitoring isn't just a compliance checkbox — it's the foundation of a trustworthy email program. DuoCircle gives you the tools to see exactly what's happening with your domain's email traffic and act on it.
See every source sending email under your domain — legitimate senders, misconfigurations, and malicious actors — all in one clear, consolidated dashboard.
Verify that your SPF and DKIM records are correctly aligned with your DMARC policy so authenticated mail reaches the inbox every time.
Instantly identify third-party or unauthorized sources attempting to send email as your domain, before they reach your customers or partners.
Move from 'monitor' to 'reject' with confidence. DuoCircle walks you through tightening your DMARC policy without accidentally blocking legitimate mail.
Continuous monitoring of your email deliverability performance ensures authentication issues are caught and resolved before they impact your sender reputation.
Manage DMARC, DKIM, and SPF together in a single platform — no juggling between disconnected tools or reading raw XML reports manually.
Without DMARC enforcement, anyone can send an email that appears to come from your domain. Cybercriminals exploit this to launch phishing campaigns that impersonate your brand, targeting your customers, employees, and partners.

DuoCircle's DMARC Monitoring puts you in control. You'll know exactly which mail servers are authorized to send on your behalf, receive alerts when anomalies appear, and have the data you need to enforce a strict DMARC policy that closes the door on spoofing attacks.
