Efectivamente, prescindir de los elementos textuales en los correos publicitarios, o usarlos simplemente como elementos de despiste, e incluir todos los mensajes dentro de las imágenes enviadas a las víctimas. Un ejemplo se muestra en la imagen adjunta, tomada de un correo no deseado que he recibido recientemente.


En el mensaje se incluía esta imagen, acompañada de un texto enorme que con toda seguridad dejaría fuera de juego a un sistema de detección de spam basado en simples estadísticas de aparición de textos:
