An electronic message based advance notification system for delivery of content relating to user selected areas of interest. A user profile database is created, each profile having a user identifier, a data identifying items or subjects of interest, and a user notice descriptor identifying the address and media for messaging to the user. A broadcast request, via e-mail or web form, having a content body data and a notice descriptor data is received. A notice is transmitted to users having a profile matching the notice descriptor, the notice identifying a subsequent broadcast by subject, source address, and time for broadcast. The subsequent broadcast is then made available at the indicated time and source address.
