Abstract: An exemplary method is implemented by end-user communication devices for transmitting and receiving HTTP messages in which acknowledgement of receipt by an addressee of an email is requested by an originator of the email. An acknowledgement request command is stored in a command portion of a user data segment of a received HTTP message. Upon receipt of the HTTP message by the addressee device, a reply HTTP message with an acknowledgement request must be authorized to be transmitted to the originator in order to allow the addressee to be able to view the content of the received HTTP message.

Abstract: An exemplary method processes an electronic communication received by a first end-user communication device, where the electronic communication comprises a digital packet having a header segment and a user data segment. A determination is made whether the received user data segment contains a first label that identifies a corresponding enhanced services application program stored in memory of the first end-user communication device. On identifying a first label, a determination is made whether the received user data segment contains a first command that identifies a corresponding action to be taken by the first enhanced services application program. On determining the existence of a first command, the first enhanced services application program causes a first action corresponding to the first command to be executed on the first end-user communication device.
