There is no simple way to send HTML mail from within mail.app, if you set as plain text and type in the HTML, it sends it as text, displaying the tags. if you attach a HTML file, it sends as attachment (I tested it, hoping it would display inline, just like image attachments). but here’s the simple way to do it:
- Open the HTML page you want to send in Safari 2.0 (Tiger)
- Select File > Mail contents of this page (or command + I)
- send your HTML Mail!
