Last month I got my 2007 Volkswagen Beetle serviced. The warranty expires December 2010. The sales guy from the dealership is calling and emailing me and I have not responded yet. HOWEVER, I can promise you that when I buy, I will buy from him (hope he's still there in December!). He has reached out to me four (4) times. Have been busy and traveling and this is not a priority right now.
This experience has totally inspired me because because I have prospects who are not responding to my outreach and that does not mean that they are not a viable prospect. If they are not responding, all I know for certain is that this is "not the right time."
So hang in there, stay pleasant and friendly via voice mail and email, maybe send a card through www.sendoutcards.com. You never know when you will call at "just the right time!" Stop making up stories about why they are not responding and then buying into your story. This is a major tip on overcoming Sales Call Reluctance! Stop the story that spirals you into self-doubt.
