Yes, there are several ways to automatically receive alerts when new emails land in your Inbox!
The Yahoo! Toolbar puts everything you want on the Web just one click away. And it alerts you when new messages appear in your Yahoo! Mail account. To learn more or to download the toolbar, visit the Yahoo! Toolbar home page.
Yahoo! Messenger is the next best thing to being there. It's super fast, and absolutely free! Yahoo! Messenger shows you new mail alerts no matter where you are on the Internet. To learn more about Yahoo! Messenger or to download the latest version, visit the Yahoo! Messenger home page.
Your Mobile Phone or Device
The thing about cell phones and other mobile devices is, you're never out of touch. So why not get email alerts when you're mobile? Done. Visit Yahoo! Mobile to find out how.
Note: Alerts only work with your Yahoo! Mail account and not with any other email accounts. You can be alerted of new messages in only one Yahoo! Mail account at a time. If you use more than one account, you won't be able to receive alerts for all of them at once—just the account you're signed into.
