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. It has plenty of time-saving tools for loading, splitting and merging lists. 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. IMPORTANT: This is not spamming software. Juggler must never be used for sending offensive messages or unsolicited promotional material. The program contains features to help combat spammers!
