No email should be sent today without you double checking it first. Besides spelling errors, how is the tone? Are you coming off as sarcastic or just mean? Your communication could be easily misconstrued today if you are not 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, then try to speak face to face or over the phone. It's the safest tactic for you, today.
