I can only say what works for me, combined with inspiration from Derek Pilcher of The Ladders. Remember that having to chase-up suggests you are not top of the priority list and this may be an “amber warning” for you to address outstanding issues. Having to leave a message could itself hold a message to you about the timing of your call. So leave a message that nurtures the relationship.
Decide how important this person is to your long term interests and consider how willing you are to lose their custom. Make it easy for your listener by taking a minute to plan the message.
- Your Name when you start and last thing when you finish.
- Your phone number, twice, the 1st at normal speed, the 2nd slowly enough for writing it down.
- A reminder of your relationship and how you have previously interacted
- An upbeat message about why you are calling and a benefit for them. People do not like associating with guillt feelings, so do not say they have not returned your call
- A pleasant reiteration of your interest and request an action.
