Alert test execution is successful but email is not sent

Overview

An incorrect sender email address for email alerts is causing the email alert notification to fail. This is even after the test execution or simulation was successful.

Environment

NPM v11.5.2

Cause 

The sender details are incorrect. In this example, the incorrect email address (nobody@nobody.com) is causing the issue. Another cause could be due to the SMTP server filtering the email address as spam because of its format.

Resolution

1. Go to the Web Console and navigate to Home > Alerts > Manage Alerts.
2. Select the alert that is failing to send the notification and click Edit Alert.
3. Go to Trigger Actions > Sender Details and expand the option by clicking +.
4. In the Reply Address field, the correct format should be name@yourdomain.com.
