Delivering an electronic notification to an intended recipient may include communicating an electronic notification directed to an intended recipient, and determining presence information associated with the intended recipient before attempting to deliver the notification to the intended recipient. A cascaded delivery instruction also may be resolved based on notification information. The presence information and the cascaded delivery instruction may be used to select among several delivery mechanisms potentially available for the intended recipient based on the presence information, and to deliver the electronic notification to the intended recipient at the selected delivery mechanism. The presence information may include an online presence and/or a physical presence of the intended recipient.
