See when secure inbound email delivery fails.
Collect TLS reports in one place and identify failures involving certificates, encryption,
MTA-STS, DANE, or MX configuration.
Pair TLS reporting with hosted MTA-STS.
Start an MTA-STS policy in testing mode, review real-world TLS failures, and move to enforcement after confirming your mail servers are ready.
Understand TLS failures without reading raw reports.
See which email providers deliver to your domain, compare successful and failed sessions, and expand any reporter to identify the failure reasons. When you need more detail, open the originating TLS report.
Add your domains and start monitoring.
Update one DNS record and your first reports will show up in the dashboard.
