The present invention provides a method of transmitting electronic communication where the sender includes an instruction set with the electronic communication. A sending computer encrypts the electronic communication and sends both the encrypted communication and the instruction set to a receiving computer. The instruction set executes a set of pre-determined operations designed to protect the content of the electronic communication if an unauthorized recipient attempts to access the contents. Further, the instruction set includes instructions that delete the electronic communication if the recipient does not retrieve the communication within a pre-determined time period.
