While I understand fully your reasoning FE, I wouldn't dream of opening up a html email without first looking at the source code. In fact, I have that option permanently disabled and I have to opt in to see the full rendition if I choose to. And most of the time I don't. So all sorts of pretty formatting are wasted on me! All I want to see is - who is it from and what do you want.
Sorry LastChiop but that is a bit paranoic. If you have a decent malware program then any nasty would be caught by it anyway. Used html email for years and never had any problem. Use common sense is the best protection.
I doubt that the website did send an email but the company or other organisation running the site did.
I can get an email which states that is better viewed in html or in my browser because then the graphics show up better. It is fairly common. How to view it depends on email client which we don't know.
Sorry alanrwood, your post shows me you maybe a bit nieve. If you believe anti-malware software will keep you safe, you need to think again. I've seen enough broken machines (and people) complete with a plethora of anti-this and that software, to throw that right out of the window. However, I totally agree with you, common sense is the best protection, no mater what system you're using.
Perhaps I do suffer a bit from paranoia, but with good reason. No anti software is 100% effective and new attack vectors are coming on-line daily. Sadly, the darker side of this wonderful invention we call the web.
Even though I have championed Linux for years now, and it is undoubtedly a more secure system than Windows, it too sees attacks not via the kernal, but via web browsers. The bad boys have discovered it's an easier way in.
Batch, web browsers in general have a far higher resistance to attack than email clients. Many will give you a warning if it believes you've visited a malicious site. That said, (as will be well known here), dodgy web sites can and will infect your PC. So my advice would be, if you see a warning, pay heed to it unless you know for sure it's a safe site. Far too many people ignore warnings and sooner or later it comes back and bites them hard.
