How to Send HTML Email From Hotmailby Stephen Lilley
If you want to send HTML-formatted email from your Hotmail user account, you're going to need to enable Hotmail's Rich Text Editor. This will allow you to insert graphical elements and formatting settings into email messages the same way you would be able to if you were writing the code on a webpage. Enabling the sending of HTML email from Hotmail is as simple as turning on a specific feature in your account.
Log in to your Hotmail account.
Click "New." This will open a new message-composition window.
Click "Plain Text" at the top of the New Message screen. This will change the text from "Plain Text" to "Rich Text Editor." Hotmail's HTML email functions are now enabled, and you can send emails formatted using HTML.
