I am interested in possible doing an e-mail campaign with constant contact, but need to know where I can obtain e-mail address of people interested in my service. I would also be very interested in hearing the best ways to attract traffic to my website. Thank you all...
First, I suggest looking at Search Engine Optimization (SEO) for your website.
Also, register (make a listing for) your business on as many well-known websites as possible (i.e. Google, wikipedia, etc.)
May I ask: What "type" of service is this? There are probably websites were people that are interested in your type service might congregate.
