No e-mail should be sent today without you double-checking it first. Besides spelling errors, how is the tone? Are you coming off as sarcastic or mean? Your communication could be easily misconstrued today if you aren’t careful. Sure, you know what you mean, but the person on the other end doesn’t. If you don’t have the time to ensure perfection in your written words, try to speak in person or over the phone. It’s the safest tactic for you today.
