DMARCsimple Feature

Domain Monitoring

Continuous monitoring of your email authentication configuration. Get alerted to changes, new senders, and potential threats before they cause problems.

What Gets Monitored

DMARCsimple continuously monitors your domain for:

  • DMARC record changes — Policy modifications, reporting address changes
  • SPF record changes — Added or removed sending sources
  • DKIM configuration — Key changes, selector modifications
  • New sending sources — Services sending email as your domain
  • Authentication failures — Spike in failed messages
  • Potential spoofing — Unauthorized sending attempts

Alert Types

Configuration Alerts

Get notified when DNS records change — whether intentionally or accidentally. Catch misconfigurations before they affect deliverability.

New Source Alerts

When a new service starts sending email as your domain, you'll know immediately. Legitimate new tool? Approve it. Unknown source? Investigate.

Failure Spike Alerts

Sudden increase in authentication failures can indicate configuration problems or active abuse. Early detection means faster resolution.

Compliance Alerts

Tracking toward DMARC enforcement? Get alerted when you're ready to move to the next policy level, or if issues would prevent safe progression.

DNS Record Tracking

DMARCsimple maintains a history of your DNS records:

  • See when records changed and what changed
  • Compare current vs previous configurations
  • Identify who made changes (if integrated with your DNS provider)
  • Roll back to previous configurations if needed

Compliance Monitoring

For organizations working toward Google/Yahoo sender requirements:

  • Dedicated compliance dashboard
  • Checklist of requirements
  • Progress tracking over time
  • Remediation guidance for non-compliant items
