A system determines that resource activity notifications, including at least a first notification and a second notification, are to be sent to a client device operated by a user. The first notification includes a first user interface element, and the second notification includes a second user interface element. The system determines, based on content of the resource activity notifications, that a subset of the resource activity notifications are contextually related, the subset including at least the first notification and the second notification. The system provides the first subset of the resource activity notifications to the client device as a first group, thus enabling the user to operate a user interface of the client device to select the first user interface element to take a first action and to select the second user interface element to take a second action.
