Nudge the undecided prospect with a ;lift; letter. These are short, powerful notes that take a different perspective and strive to persuade those still sitting on the fence to take action. This is another effective way to use a pop,up window to take one final opportunity to win a favorable response. This extra push works best when the words are spoken by another person – preferable a happy customer or someone of high standing , in the prospect's eyes. The purpose here is to get them to reconsider and to reassure them that they have nothing to worry about.
