You ever try to tell a joke in an email…or express sarcasm…or do anything to convey tone…and it falls flat?
It’s happened to me a few times, and let’s just say it’s pretty awkward. Email is good for communicating information, not necessarily tone.
Before sending that email, ask yourself how you would interpret the words if you were the recipient. What might sound like a joke to you might be interpreted as an insult.
