This proved to be the most effective debt-collecting email I have ever written. Every client settled their account within two days, while two called to apologize within minutes of receiving my email. I chose to abandon the stiff business approach and instead write one very human email, carefully worded to express how I personally felt. After all, business may be business, but people work with people. This exercise taught me that even the trickiest situations can be handled better and resolved faster by plain, honest communication.
