Yes. Building out a list of pre-qualified contacts, then "cold calling" by means of telephone or email is one of the best ways to get in front of people that your product/service can help. The key is to be respectful of everyone's time and come to the table with something of value. And of course, pushiness or over-persistence is never appreciated. Also, "cold call" doesn't mean "blind call". The sales person should have some notion of the prospect's business, their role in that organization, and exactly where this product or service might fit in.

To those that hate receiving cold calls, remember: most of these sales development folks that call leads are fresh out of school and simply trying to gain a foothold in a hyper-competitive space. Don't let them waste your time if that's what they're doing, but have a heart!
