TLS-RPT Monitoring
Receive and analyze TLS failure reports. Know when senders can't establish secure connections to your mail servers.
What is TLS-RPT?
TLS-RPT (TLS Reporting) is a standard that allows sending mail servers to report TLS connection failures back to receiving domains.
When a sender tries to deliver email but can't establish a secure TLS connection, they send you a report explaining what went wrong.
Proactive TLS monitoring
Don't wait for delivery failures. TLS-RPT tells you about encryption issues before they impact your users.
Report Parsing
We receive and parse TLS-RPT reports from major email providers. Human-readable summaries, not raw JSON.
Failure Analysis
Understand why connections failed: certificate errors, policy mismatches, or MX hostname issues.
Trend Tracking
Track TLS success rates over time. Spot degradation before it becomes a critical issue.
Instant Alerts
Get notified immediately when TLS failures spike. Email, Slack, Teams, or webhook notifications.
MTA-STS Integration
TLS-RPT works with MTA-STS to provide complete visibility into your email encryption status.
Easy Setup
Just add a DNS record pointing to our reporting address. We handle everything else automatically.
Know when TLS connections fail
TLS-RPT monitoring is included with Basic plans and above.
