A figlet "encoded" string might be almost decipherable to someone who views it in something other than a fixed width font.

Ah, somthing else I didn't think about! I only use fixed font plain text viewing myself...

I thought of FIGlets since they are easy to create, easy to read by the human eye, but require work to decode by a computer, and I don't think a mass-mailer would bother to do that.

Thanks for your input.
