If you accidentally forgot to buy the whois guard for your domain, you'll get a lot of these stuff these days, including website designs. But i personally don't take it as bad as spam, just another way of marketing imo.

Yeah, I have a couple of sites without whois, and I got an SEO spam email yesterday. The idea of trusting a spammer with my SEO is scary....

All I can say is that you must be awfully brave opening media mail from strangers! That's how viruses are spread.

Ya there are lots of this type of promo works are undertaking but this may cause of spreading malicious program so generally we should avoid all this.
