Many people like to use HTML e-mail because it looks good. If you send plain text e-mail, then your missives won't be accompanied by bouncing smiley faces and cutesy-wootsie bunnies hopping.
The downside is that HTML e-mail can easily hide worms, viruses, trojans, spam bots,
etc. When you open an HTML e-mail that includes a nasty, you may trigger that nasty and infect your computer. People who open HTML e-mail are what we techies call "Revenue Sources".
Despite anyone's best efforts at security, someday we're all going to get hit by some mutant hacker's creation. Most of those hits will arrive via HTML e-mail.
If you use Microsoft Outlook as your e-mail client software, you need PocketKnife Peek, a small
free Outlook add-in that allows you to preview your HTML email as text. I do not use Outlook for e-mail unless I have
PocketKnife Peek installed.
While we are on the topic of HTML e-mail, nasties, and Outlook:
Always remember that when you use Outlook's Preview Pane option, that you automatically open whichever e-mail is highlighted in whichever folder is open.
Never, ever use Outlook's Preview Pain (intentionally spelled that way), unless you enjoy being some techie's cash cow.
