You care about making a good impression in person, so why not hold your email persona to the same standard? “Email is a reflection of you and should be written like a letter more than a text, while still keeping in mind brevity,” says Symington. Check your spelling, grammar, and punctuation. All caps indicates you’re yelling, and all lowercase implies you’re lazy. Too many fonts, colors, and smiley faces can be irritating, she adds.
Be friendly without trying to overdo the humor. “Err on the side of caution even if you have a sense of humor,” says Gottsman. Tone is too often muddled in email, and you don’t want to come off as unprofessional because someone doesn’t get your joke.
