Email Address Juggler
Email Address Juggler is a great program for sorting-out large numbers of email addresses. It's perfect for keeping your friends, customers or club members up to date. If somebody decides they want out from a list, add them to the removals list to make sure that you don't bother them again. When you've got your list ready, use the built-in international spell-checker to check your message and then send it out with a click of the mouse.
