Abstract: A method and system are provided that communicate interactive event reminder messages across various communications platforms. According to one or more aspects of the present invention, an intended recipient for an event reminder message is defined by, for example, manual entry or interaction with a contacts list. The event reminder message content (e.g., text message, voice message, etc.) is defined. A date and time for transmitting the event reminder message is selected by, for example, manual entry or interaction with a calendar or scheduling application. A delivery method, e.g., telephony message, e-mail, SMS message, is selected for delivery of the event reminder message. The message is then transmitted to the intended recipient using the selected delivery method. Other aspects of the present invention provide for event reminder message receipt verification, and for the recipient to perform certain predefined actions in response to receipt of the event reminder message.
