There are a few ways to contact investors.
I believe the best way to do this is to find someone who can make a warm introduction for you via email. Then taking it from there. If you can find someone that you know who knows the investor.
Sending an email without knowing an investor before hand is hard because investors get 100’s of email a day from potentail companies to invest in.
Listening to Jason Calacanis’s on the podcast This Week In Startups he talks about the best way to contact investors via email. Some great advise from him, never send powerpoints, don’t email investors at strange hours of the night with your business ideas. Screenshots or a URL are good. Listen to these few minutes, they are very good: mp3>.
Howard Morgan from First Round Capital says he will never open a .doc file. He doesn’t want to get a computer virus.
