real answers please no spam to your websites etc

I’m doing an essay on the stock market, and while finding pieces on lives ruined by the market were easy to find, finding the opposite is proving extremely difficult. I’ve been Googling it for a while, but the only thing that comes up is obvious spam.
And if you could name someone who was both positively and negatively influenced by the stock market, that would be even more fantastic.

To get tips and information from?
NO SPAM!!!

My target market are certain businesses who already have their email addresses listed on the internet. If I send a promotional email to them is this considered spam?

I am a real estate agent and want to market via internet without being labeled as SPAM. I want to send my ads out in large blasts.
