You can select to have all alerts held and sent once a day using the daily digest feature.
Note
Trellix recommends using Per Event notifications instead of Daily Digest notifications. If you do not want Daily Digest notifications, ensure the Daily Digest check box is not selected.
To set up a daily digest of alerts:
Open Settings > Notifications.
Under Define daily digest, select the Daily Digest check box.
Set the time to send the daily digest notification.
Click Update Digest.
