Deliverability Reporting
The Deliverability Reporting page provides detailed visibility into the delivery status of outbound emails processed through the Cloud SMTP Relay.
It allows administrators to:
Monitor outbound email delivery
Track performance
Identify delivery failures
Analyze trends such as bounces, rejections, or delays.
Using built-in filters and customizable columns, administrators can quickly isolate emails by delivery status, sender, recipient, or subject, making it easier to troubleshoot deliverability issues and maintain a strong sender reputation.
If an email provider does not update their user reporting emails as spam or phishing, these reports will not appear in the Deliverability Reporting page.
To view and monitor outbound emails processed through the cloud SMTP relay:
-
From the left navigation panel, go to Security Settings > Relay > Deliverability.
