If you are an admin, make sure the toggle for “All Group Alerts” is ON.

Click on a user’s name in the “Recipients” column of the alert you are editing.

To add a user to the alert, check the box by their name, then click Turn On Alert and select the delivery frequency from the drop-down list. Then close the box.

To remove a user from the alert, check the box by their name, then click Turn Off Alert. Then close the box.

Tip: Frequencies set to “None” mean the alert is off for that user.
