Abstract: A system for facilitating email communications. The system includes a first mechanism for monitoring when emails are sent and/or how often the emails are sent to different email addresses and providing a signal in response thereto. A second mechanism selectively displays a list of most recently used email addresses and/or most frequently used email addresses based on the signal and based on user input. In a specific embodiment, the first mechanism includes email address usage-tracking software that interfaces with email communications software. Email address sorting software communicates with the email address usage-tracking software and employs a data structure that contains priorities associated with a predetermined number of email addresses. The predetermined number of email addresses is user-configurable via a user-interface to the email address sorting software. The email address sorting software sorts email addresses in a data structure according to priority values assigned to each email.
