How to Create Mail Groups in Yahoo

Mail groups help to reduce the stress on your clicking finger by allowing you to group multiple contacts together under one catch-all name, such as "Friends" or "Sales Team." After you create a mail group and populate it with a list of contacts, sending an email with the mail group as the recipient will send the message to everyone in the group. Mail groups go by many names, depending on your software and email provider; Yahoo! calls them "Categories."
