Like any other email, messages sent over SMTP bounce around the internet unencrypted from server to server before they arrive. Messages delivered over SMTP are generally not supported by the wireless service providers for content delivery and mobile marketing therefore receipt of the messages cannot be confirmed. Also, volume messages sent over SMTP can easily be caught in Spam filters.
