DMARCdrift

DMARCdrift provides monitoring and alerting for DMARC alignment issues and potential spoofing across email domains. It addresses the challenge of interpreting DMARC aggregate reports, which typically arrive as gzipped XML files that are difficult for most users to read and act upon. By parsing these reports, DMARCdrift notifies users when there are signs of alignment regression, unknown senders, or possible spoofing activity affecting their domains.

The platform delivers specific alerts, such as notifications when alignment percentages drop or when new, unrecognized senders appear. For example, it can detect a new sender IP address with no DMARC alignment and flag it as a potential spoofing source. It also provides digest summaries showing alignment rates and message counts for different senders, including common email service providers like Google Workspace, Mailchimp, and Outlook. This allows domain administrators to quickly review and address issues that could impact email deliverability or security.

DMARCdrift is accessible via the web and offers a free tier that allows monitoring of a single domain without requiring a credit card. The service features flat pricing and does not require enterprise contracts, making it suitable for organizations or individuals who need straightforward DMARC monitoring without complex setup. Alerts and digests are sent by email, providing actionable information to help maintain domain alignment and prevent silent deliverability failures.
