Personally I've always used my proper business email address. If a prospective client has to fiddle about or, even worse, fill in a form they just move on to the next till they find an email address they can click on and say "hi, I need ...., can you help me?".

How often have you, in looking for something via the web, moved right on because there was no clear email address or phone number? I know I do, always. How many successful companies hide their precise contact (email, phone number and location) information? Spam emails, just delete. I especially like the ones that want me to buy something to enhance a part of anatomy I don't have

Just my two pennyworth.
