You should seriously consider purchasing a commercial company directory. Most companies providing these services can provide you with Excel, CSV or XML files which you can easily iterate with your desired scripting language.

Not only will you have more prospects faster, chances are you will not get listings for companies who do not want to be targeted by direct-mail marketing, which is a wish that should be respected.

Right now you are setting yourself up for spam-complaints, which could result in your email domain or server getting blacklisted. Think carefully before choosing your strategy.
