A messaging system and method with dead man switching providing for hierarchical delivery of messages based on selected message hierarchy levels with controlled delivery/response timing is disclosed. The system and method incorporates a messaging host that communicates with a messaging source client that creates and prioritizes a message and targets address(es) for the message. This message is then transmitted to the target address(es) using a hierarchical transmission thread having set limits on response times for each address within the thread. Reception of the message by each target(s) produces visual and/or auditory notification at the target(s). Messages are automatically forwarded to remaining target(s) within the thread upon expiration of a timer should the target(s) fail to respond to the message within a predetermined time. Failure of the target(s) to respond to the message(s) is reported bi-directionally along the thread and forwarded to remaining target(s) in the thread.
