Click the corresponding "Select" button or the image that displays the control panel you use to create, edit, and delete email addresses.
Unsure which service you use? Here are a few ways you can check:
If you are the owner of your plan, go to your Business Control Panel and choose the "Email Control Panel" link. Choose the image above that matches your Email Control Panel.
If you use a POP mail client to retrieve and manage your messages, check the POP settings in your desktop client (see your software's documentation for more information).
If your incoming mail (POP3) server is pop.mail.yahoo.com, you use Personal Address. If you see pop.bizmail.yahoo.com, you use Business Mail.
If you send and receive your mail using the Webmail interface, check the web address you use to access your mailbox.
Business Mail users can sign in by going directly to http://mail.widgetdesigns.com/ (be sure to replace "widgetdesigns.com" with your domain name) and entering their Yahoo! ID and password. If you use Personal Email, you'll sign in at http://mail.yahoo.com/ (going to http://mail.widgetdesigns.com/ will automatically reroute you to http://mail.yahoo.com/).
