The exact change

Before

"Anger and specificity are the two most important dials in a complaint letter, and most people turn the anger dial up and the specificity dial down. The letters that get results do the opposite." Michelle Singletary, Washington Post personal finance columnist [...] "Every sentence in a complaint letter is a small decision about whether to be credible or to be loud. Credibility wins, almost every time." Liz Ryan, former Fortune 500 HR executive [...] "The complaint letters that succeed are almost always backed by documents the writer assembled before they started typing. Assembling the evidence often clarifies what the actual claim is, which is why the best first step in a complaint is to spend an hour collecting your own records." Michelle Singletary, Washington Post [...] "When I am teaching complaint writing, I tell students to imagine their letter being read aloud in a courtroom by their attorney. Every sentence that would make the attorney wince should be cut. That constraint alone produces better complaint letters." Alison Green, Ask a Manager

After

Personal finance writers such as Washington Post columnist Michelle Singletary have long advised that effective complaint letters turn the anger down and the specificity up, since most letters that fail to get results do the opposite. [...] Communication professionals like Liz Ryan have made the point that every sentence in a complaint letter is effectively a choice between sounding credible and sounding loud, and that credibility tends to win out in getting results. [...] Consumer finance writers such as Michelle Singletary have advised that successful complaint letters are almost always backed by documentation the writer gathered before drafting, and that assembling the evidence first often clarifies what the actual claim should be. [...] A useful discipline recommended by workplace writers like Alison Green is to imagine the letter being read aloud in a courtroom by your own attorney, and cutting any sentence that would make the attorney wince.
