Yahoo Mail has added a cool font application called Cool Fonts. Cool fonts helps you to create colorful emails. Just launch the My Cool Fonts app from the Applications menu, select a font, type a message, click on “Create email” and voila! A new email gets created, and you can then add any other text or attachments to your illustrated message.
Most of these fonts have its their own set of smileys, which you can browse and easily insert into your message from the Smileys menu. See the whole list here.
