I received one of these too. I checked with my wife and she also received one. [separate businesses] We both think it is a scam. I would delete it and never look back. I didn't even go look at the website, since that can work against you too. A spammer like that probably has a way to install identity theft junk, robots, or adware on your computer if you go forward.
Are there no good business names left? The only one available was hotfrog?
