A system for transmitting information to users via a website or mobile application is described herein. The system includes a database and a server including a processor. The processor is programmed to receive a transmittal request to transmit a communication message to a recipient address, select a recipient type associated with the recipient address, and responsively generate a unique communication identifier including information indicative of the selected recipient type and the communication message. The processor generates and transmits a notification message including the unique communication identifier to the recipient address. The processor also receives a display request to display the communication message in response to a recipient user accessing the unique communication identifier including the selected recipient type. The processor determines promotional information associated with the recipient type and displays the communication message and the associated promotional information to the recipient user via user computing device.
