HTML email considered harmful (TV Licensing)

The problem of companies sending out HTML emails is getting worse, certainly in the UK I just received my TV License email, and the email only said "Your TV Licence is available". I needed to switch Thunderbird to view the message body as HTML to be able to get to the rest of the information. (Thunderbird Message Body naming isn't ideal either).

The automated email from TV Licensing now also uses a from address indicating they don't even want me to contact them, donotreply@tvlicensing.co.uk, their sender address bounces@tv-l.co.uk actually bounces when I tried to reply to them. Visit the TV Licensing site and you're presented with this link "Click here to fill in a short email form", a contradiction as the web-form is worse than usual, a tiny box which they try to give an automated answer, shifting yet more cost saving on to my back when I only wanted to let them know they were sending out empty emails.

Most spam I get uses HTML tricks to get through my ISP filters, a good reason if any not to support HTML email. HTML email is useful for sending tables of information, but then we could all just attach the OpenOffice file to the email!
