11 Email Etiquette Rules Every Professional Should Know

If you work for a company, you should use your company email address. But if you use a personal email account — whether you are self-employed or just like using it occasionally for work-related correspondences — you should be careful when choosing that address, says Pachter.

You should always have an email address that conveys your name so that the recipient knows exactly who's sending the email. Never use email addresses (perhaps remnants of your grade-school days) that are not appropriate for use in the workplace, such as "babygirl@..." or "beerlover@..." — no matter how much you love a cold brew.

No one wants to read emails from 20 people when it has nothing to do with them. They could just ignore the emails, but many people get notifications of new messages on their smartphones or distracting pop-up messages on their computer screens. Refrain from hitting "reply all" unless you really think everyone on the list needs to receive the email, says Pachter.

Don't use laid-back, colloquial expressions like, "Hey you guys," "Yo," or "Hi folks."

"The relaxed nature of our writings should not affect the salutation in an email," she says. "Hey is a very informal salutation and generally it should not be used in the workplace. And Yo is not okay either. Use Hi or Hello instead."

She also advises against shortening anyone's name. Say "Hi Michael," unless you're certain he prefers to be called "Mike."

If you choose to use an exclamation point, use only one to convey excitement, says Pachter.

"People sometimes get carried away and put a number of exclamation points at the end of their sentences. The result can appear too emotional or immature," she writes. "Exclamation points should be used sparingly in writing."

Humor can easily get lost in translation without the right tone or facial expressions. In a professional exchange, it's better to leave humor out of emails unless you know the recipient well. Also, something that you think is funny might not be funny to someone else.

Pachter says: "Something perceived as funny when spoken may come across very differently when written. When in doubt, leave it out."

Miscommunication can easily occur due to cultural differences, especially in the writing form when we can't see each other's body language. Tailor your message depending on the receiver's cultural background or how well you know them.

A good rule to keep in mind, says Pachter, is that high-context cultures (Japanese, Arab, or Chinese) want to get to know you before doing business with you. Therefore, it may be common for business associates from these countries to be more personal in their writings. On the other hand, people from low-context cultures (German, American, or Scandinavian) prefer to get to the point very quickly.

It's difficult to reply to every email message ever sent to you, but you should try to, says Pachter. This includes when the email was accidentally sent to you, especially if the sender is expecting a reply. A reply isn't necessary, but serves as good email etiquette, especially if this person works in the same company or industry as you.

Here's an example reply: "I know you're very busy, but I don't think you meant to send this email to me. And I wanted to let you know so you can send it to the correct person."

Your mistakes won't go unnoticed by the recipients of your email. "And, depending upon the recipient, you may be judged for making them," she says.

Don't rely on spell-checkers. Read and re-read your email a few times, preferably aloud, before sending it off.

"One supervisor intended to write 'Sorry for the inconvenience.' But he relied on his spell-check and ended up writing 'Sorry for the incontinence.'"

"You don't want to send an email accidentally before you have finished writing and proofing the message," Pachter says. "Even when you are replying to a message, it's a good precaution to delete the recipient's address and insert it only when you are sure the message is ready to be sent."

She says to pay careful attention when typing a name from your address book on the email's "To" line. "It's easy to select the wrong name, which can be embarrassing to you and to the person who receives the email by mistake."
