Emails can create emotionally charged situations and grave misunderstandings. Here is how to keep your tone in check with a new app.

There is email etiquette in how to properly communicate with appropriate punctuation spelling and now for tone.

Psychologists have found that you have a 50-50 chance of accurately understanding the tone of an email message whereas you are convinced 90 percent of the time that you correctly assessed the tone. The findings were published in the December 2005 edition of the Journal of Personality and Social Psychology.

Co-author of the study Nicolas Epley, PhD, professor of behavioral science and Neubauer Family Faculty Fellow at the University of Chicago, said in a February 2006 Monitor on Psychology article, "E-mail is fine if you just want to communicate content, but not any emotional material."

However a new web-app tool, ToneCheck, described as an emotional spellcheck for tone introduced on July 20, is trying to help your chances as a sender of being understood. claims that it "helps people write better and prevent them from saying stupid things," and offers "emotional ratings" based on "eight primary emotions" including affection, loathing, grief and shame for better phrasing.
