A system and method is provided for transmitting data (e.g., an advertisement, etc.) over a wide area network, such as the Internet, in response to receiving and authenticating at least a portion of mail data. In one embodiment of the present invention, a mail verification application is adapted to store mail data in memory. The mail data is then affixed to a mail object. The mail object is then manually delivered to a recipient. The mail data is then provided to a reception device. The reception device, which communicates with the mail ID device over a wide area network, transmits the mail data to the mail verification application operating on a mail device. The mail verification application then compares the received data with the data stored in memory. If the received mail data is authenticated, data (e.g., an advertisement, etc.) is sent to the reception device.
