Quickbuilder is a handy feature in your Yahoo!Xtra Address Book that lets you add contacts from emails you currently have stored in Yahoo!Xtra Mail.

Start by clicking the "Quickbuilder" button located next to "Add Contact" and "Add Category." QuickBuilder setup allows you to search your Yahoo!Xtra Mail messages for contacts and add them to your address book. You can customize your search criteria to narrow your results. Once you get your search results, you can use the checkboxes to add these contacts to your Yahoo!Xtra Address Book.
