A rose is a rose. And a sales call is either cold or hot. No exceptions.
Hot calls can yield a fantastic rate of return, but unless your prospects know you or are expecting you to reach out, it's a cold call. And if you make 100 cold calls, you may talk to about 20 people, schedule 10 appointments, and if you're lucky, close one new deal. That's a 1 percent return on your time.
