You can use Thresholds to filter out anomalies that might not be useful for you.
There are two different threshold that can be configured:
Cost variation amount
Cost variation percentage
If you want to configure your own threshold, click on the menu button in the top-right corner, and select Change anomaly alerts.
In the Anomaly alerts screen, check the field(s) you wish to use and enter your desired values.
An email alert (on the email associated to your ShareGate Overcast account) is sent by ShareGate Overcast only when an anomaly is detected.
If an anomaly is detected, you will receive an email at 7:00 AM EST. There is no way to set another time for alerts.
If you want to activate email notifications, click on the menu button in the top-right corner, and select Change anomaly alerts.
In the Anomaly alerts screen check Receive email notifications.
