Entourage

Entourage is the MacIntosh equivalent of Outlook. It manages e-mail and allows you to organize them in folders for later reference. It organizes all your addresses and allows you to send mass e-mails to groups. It keeps all that information really handy and upfront for you so that you can manage it. You can make folders for your e-mails and frequently visited web addresses also. You can also customize your e-mails, add a signature with your name, address, and any other information including logos. You can block certain e-mails. It allows you to import messages from other e-mail accounts such as Yahoo or Hot Mail or your office server, which also allows you to reference your e-mails without being online.
