Formatting, fonts, and colors
You can customize MCmail messages with rich formatting, add color to your greetings, underline key points, or make your words bold. Here's how to enhance your messages:
- Click Compose Mail at the top of any Gmail page.
 - Click the icon for the formatting feature you'd like to use in the formatting toolbar above the compose window. If you don't see any icons, click Rich formatting » to display all formatting options.
 - Type your message! (Please note that Gmail doesn't recognize HTML tags inserted in the body of a message.)
 
If you decide you'd like to write a message in plain text format, just click « Plain text along the top of the compose window.
