Most sales people give up after the 3rd attempt to prospect a client. Most results start to happen after the 7th the attempt. Some take over 12 attempts. Some even longer! When you stop following up, the sales opportunity is lost forever. Great sales people never stop following up. The more you follow up, the more you will sell. The more effective that you do follow ups, the faster you will sell more! Face-to-face follow ups can be the most effective.
