For most organizations, e-mail is the communications medium of choice. Whether it is driving one-to-one marketing, customer service follow-ups, order confirmations or one-off communications between internal employees and customers, e-mail has proven a highly effective tool. It is inexpensive, fully trackable and — when used properly — appreciated by those who receive it.
At the same time, the misuse of e-mail has led many enterprise organizations to invest heavily in systems and software to protect themselves from receiving spam. However, these enterprise organizations invest nothing in a common platform to protect the organization from being a spammer. This common platform is essential in the enforcement of control and compliance.
