A Plain Text Signature for Plain Text Emails
Yahoo! Mail and Yahoo! Mail Classic will only use the HTML code if the message you send is in HTML, too. If you send a plain text message, a plain text equivalent of your HTML signature is used.

If you want to go beyond text even, you can also add an image to your Yahoo! Mail signature.
