Email is the single most important tool in helping employees to get work done in organizations of all sizes. Most email users have become so dependent upon their corporate email system that they check mail almost constantly while at work, most check it at home on weekdays and weekends, they check it while traveling and also while on vacation. The average email user spends nearly 30% of his or her day doing something in their email client or browser-based equivalent. And, despite the conventional wisdom, email is being used more over time – not less – as it becomes the focal point for integrating various types of communication and business processes.
