Email authentication monitoring for IT & email teams
A new sending tool. An old DNS record. A service that stopped authenticating. Ray helps you find the problems, identify the sender, and understand what needs to change.
Your free check examines published email authentication records and detects sending services in DNS.

Messages are being signed, but the domains do not match.
Illustrative monitoring view. Sender activity and pass rates become available after you connect DMARC reporting.
From “is something wrong?” to “here’s what to fix.”
Sales, marketing, support, and billing can all send as your domain. Ray brings their authentication signals together so you can see where to investigate.
Combine services detected in DNS with sender activity in DMARC reports. Investigate unfamiliar IPs, forgotten tools, and services failing authentication.
Service identification · Sender breakdowns · Subdomain discovery
Check SPF lookup limits, DKIM configuration, and DMARC policy. Use per-sender results to identify which service needs attention.
DNS analysis · SPF and DKIM alignment · DMARC results
DNS records and sending services keep changing. Hourly DNS checks and email alerts help you spot configuration changes, while report history shows authentication trends.

Start with one domain
Enter a domain to inspect its public DNS records. See authentication findings and detected services without creating an account.
Check my domain →Create your account, verify your domain, and add Ray’s reporting address to your DMARC record. You make the DNS changes with your existing provider.
As mailbox providers send reports, Ray shows sender activity and authentication results. DNS monitoring and email alerts help you keep up with changes.
Built to fit your infrastructure
Ray analyzes your configuration and reports. You decide what to change, and make those changes where your DNS already lives.

The free check gives you a concrete starting point. For a broader view, explore Ray’s public DNS Census and its email authentication findings across more than a million domains.
DNS Census is public research coverage, not a customer count.
Before you start
The free domain check analyzes public DNS records. Ongoing monitoring adds DMARC report processing, sender history, hourly DNS checks, and email alerts. Business plans start at $25/month. Compare pricing and message limits.
A DNS check detects services in your published records. Seeing actual sender activity requires DMARC reports from mailbox providers. Connect reporting in Ray to build that view as reports arrive.
No. Keep your existing providers. To enable monitoring, you verify your domain and configure its DMARC reporting address. Ray does not need credentials for your DNS account.
No. Authentication is one part of delivery. Ray helps you find authentication problems; sender reputation, message content, recipient engagement, and mailbox-provider policies also affect where email lands.
No. Ray shows findings so you can investigate and make changes with your DNS or email provider. It does not manage your DNS, flatten SPF records, or process forensic reports containing email content.
