Why DMARC Monitoring Matters
Email Deliverability
Major email providers require DMARC for optimal inbox placement. Without proper email authentication monitoring, legitimate messages may be rejected or marked as spam, impacting business communications.
Brand Protection
Email spoofing attacks damage your reputation and erode customer trust. DMARC (Domain-based Message Authentication Reporting and Conformance) protects your brand by preventing unauthorized use of your domain.
Actionable Insights
DMARC reports reveal who's sending email using your domain, both authorized and unauthorized. Understanding this activity is essential for maintaining email security and identifying potential threats.
The "Yahoogle" Mandate: Yahoo and Google Now Require DMARC
Starting February 2024, Yahoo and Google began requiring domain owners to implement DMARC to prevent spoofing and ensure email delivery. A DMARC record must be added to DNS with established SPF and DKIM authentication. Non-compliant emails may be rejected or sent to spam—especially for bulk senders (5,000+ daily emails).
While you can start with a monitoring policy (p=none), strong enforcement (quarantine or reject) is increasingly required to prevent unauthorized use of your domain. These measures protect your brand from phishing, reduce spam, and improve email deliverability.

Proven in Production
Built on technology already processing real DMARC data. See it running live at sh4meful.com before you sign up.
How It Works
Up and running in three steps.
Create a Collector
A collector is a unique RUA email address where your DMARC reports will be sent. Set up one collector per domain, or point multiple domains at a single collector. Multiple collectors is a paid feature.
Update Your DMARC DNS Record
Add your collector address to your domain's DMARC DNS record. We'll guide you through this step-by-step if you need support.
See Your Results
Reports start arriving automatically. Viewleaf parses and visualises them so you can see exactly who is sending email on behalf of your domain and how it's authenticating.
See It in Action
At-a-Glance Analytics
Your dashboard shows DMARC pass rates, authentication states, inbox likelihood, and alerts, across all your domains and collectors. Four configurable time ranges and custom date selection make trend analysis straightforward.
Deep IP Intelligence
Drill into any source IP to see who owns it, its geographic location, WHOIS registration details, reverse DNS, and a complete history of its DMARC authentication, all without leaving the app.
