A message handling system, comprising: an interface operable to receive a message intended for a constrained recipient; and processing circuitry operable to: generate a first push envelope, the first push envelope comprising a first encrypted copy of the message and first executable code that facilitates decrypting the message; generate a second push envelope, the second push envelope comprising a second encrypted copy of the message and second executable code that facilitates decrypting the message; associate the first push envelope and the second push envelope with a message index, wherein the message index uniquely identifies the message; communicate the first push envelope to the constrained recipient; and communicate the second push envelope to a viewing system, wherein the second push envelope is communicated to the viewing system independently of the constrained recipient; characterised in that the first push envelope and the second push envelope further include the message index; wherein the processing circuitry is further operable to communicate the first push envelope to the constrained recipient via a first carrier email, the first carrier email comprising information including a URL link for locating the viewing system and instructions that instruct the constrained recipient how to access the first encrypted copy of the message; and in response to the URL being invoked when the constrained recipient attempts to view the message received, receiving a request from the constrained recipient at the viewing system to locate, by the viewing system, the second encrypted copy of the message, based on the message index, and in response to a determination that the request has passed authentication, decrypt the second encrypted copy of the message and communicate a view of the message to the constrained recipient. an interface operable to receive a message intended for a constrained recipient;
