Free DMARC policy advancement simulator. Enter your domain and see the exact, risk-minimized rollout path from monitoring to full enforcement — with recommended pct= progression and dwell time at every stage.
Analysing DMARC policy…
Skysnag Monitor
Stop managing DMARC manually. Skysnag monitors your email streams, identifies unauthorized senders, and moves you safely to p=reject — without breaking delivery.
Skysnag Protect compresses a 10–16 week manual rollout into 30 days by automating sender discovery, alignment fixes, pct= progression, and continuous aggregate-report monitoring — with zero delivery incidents.
Sender Discovery
Automatically map every service sending on your behalf from aggregate reports
Alignment Fixes
Guided SPF/DKIM alignment for each discovered sender before enforcement
Automated pct= Staging
Skysnag advances the percentage tag on a schedule you approve
Aggregate Report Analysis
Daily parsing of RUA reports into actionable dashboards and alerts
Subdomain Protection
sp= policy management so subdomains cannot be spoofed during rollout
Ongoing Monitoring
Continuous checks that enforcement stays intact after new senders are added
DMARC enforcement is the process of advancing your policy from p=none (monitor-only) through p=quarantine (spam-folder failing mail) to p=reject (block failing mail entirely). Each step must be introduced carefully — an aggressive jump to p=reject without confirming that all legitimate senders are aligned will cause immediate delivery failures for payroll, invoicing, password resets, and marketing campaigns.
Once at full enforcement no unauthorized sender can impersonate your domain to employees, customers, or partners — the single strongest anti-phishing control available.
The pct= tag lets you enforce policy on a statistical sample — start at 10%, confirm no legitimate mail is caught, then advance. Each stage minimises blast radius.
DMARC aggregate reports arrive daily. Spending the recommended dwell time at each stage catches forgotten third-party senders, subdomain drift, and seasonal senders.
p=reject with pct=100 is required before you can publish BIMI and display your logo — and the Gmail blue checkmark — in recipient inboxes.
