Systems and methods for modifying campaign dependent geofences by creating marketing campaigns and linking the marketing campaign to a specific geofence. Each campaign-linked geofence may be capable of delivering the campaign messages to geofence participants during the duration of a marketing campaign and the geofence system may subsequently deactivate the geofence automatically after the marketing campaign has concluded. The systems and methods may map a geofence with a defined boundary to specified location on the map coinciding with the marketing campaign. As the tracked computer devices impinges on the borders of the market campaign's geofence, select messages may be received by the tracked computer devices, corresponding specifically to the events, promotions and advertisements of the campaign events during the time frame the events are active.
