Generally speaking, persuasive business messages rely more heavily on logical than on emotional appeals because the main idea is usually to save money, increase quality, or improve some other practical, measurable aspect of business. To find the optimum balance, consider four factors: (1 ) the actions you hope to motivate, (2 ) your readers' expectations, (3 ) the degree of resistance you need to overcome, and (4 ) your position in the formal and informal power structure of the organization. As its name implies, an emotional appeal calls on audience feelings and sympathies rather than on facts, figures, and rational arguments. Such words can help put your audience members in a positive frame of mind and help them accept your message. However, emotional appeals in business messages aren't usually effective by themselves because the audience wants proof that you can solve a business problem. A logical appeal calls on reasoning and evidence. The basic approach with a logical appeal is to make a claim based on a rational argument, supported by solid evidence. When appealing to your audience's logic, you might use three types of reasoning: analogy, indication, or deduction.
