Watch Your Tone
The universal acceptance of email and texting in day-to-day communication brings up a couple of major issues when it comes to tone.
The first problem is that tone is simply almost difficult to convey via email. As a result, we are often forced to get a little “unprofessional” with it and toss in a forced smiley or frowney face emoji to let the reader know our intended tone.
My quick and dirty rule is to stick with the facts in email. Be polite and direct. If you feel the need to add a smiley-face in there to convey your intent, rewrite the email in a more professional manner or better yet, pick up the phone.
