I'm afraid the answer is "the fact that 90% of mail agents out there 
interpret HTML by default, and 80% of users don't know what HTML is, leave 
alone knowing how to disable it in their email".

Clearly, authors of messages like that are targeting people accepting HTML 
-- and they must know what they are doing...
