Between the big things like salary negotiation strategies and the little things, like body language mistakes and nailing your business card design, there are plenty of opportunities at the office to mess up. But thanks to these nine HR and talent pros, there鈥檚 one medium we won鈥檛 have to worry about making a mistake in: email.

1. Don鈥檛 say anything you wouldn鈥檛 say face-to-face. 鈥淎 good rule of thumb is to never say anything you wouldn鈥檛 want forwarded to the entire company. More times than I can count, I鈥檝e been in situations where someone badmouths a coworker, and through one tiny typing slip-up (or one passive-aggressive forward) it ends up in the wrong hands. When in doubt, keep it nice and professional.鈥 鈥 Adrian Granzella Larssen, Editor-in-Chief of The Muse

2. Don鈥檛 criticize. 鈥淚f you have to give performance feedback, discuss an issue or constructively criticize someone, it needs to be done via phone or in person. Don鈥檛 put anything in an email that you wouldn鈥檛 want hanging in the break room. Never gossip or talk about others via email. It is inappropriate and unprofessional.鈥 鈥 Krisha Buehler, HR Manager and Culture Cultivator at eaHELP

3. Don鈥檛 say 鈥渉ey.鈥 鈥淯sing the term 鈥榟ey鈥 is one of the worst salutations you can use in a work email. Not only does it bring a casual feeling to the conversation, but studies have shown that it is received negatively, and some people even get offended when the word is used to start an email.鈥 鈥 Evan Harris, Co-Founder and HR Director of SD Equity Partners

4. Don鈥檛 email upset. 鈥淵ou never want to air your frustrations or grievances or anything that you wouldn鈥檛 want to see published with your byline. Think of the phrases we sometimes use to preface most of those types of conversations: 鈥榖etween you and me,鈥 鈥業 hate to say it, but鈥︹ and so on.鈥 鈥 Lisa Oyler, HR Director at Access Development

5. Don鈥檛 get personal. 鈥淎void sharing personal information. It can become an official record, ammunition or an embarrassment that never dies. People forward things without giving it much thought and they probably didn鈥檛 edit the email before hitting send.鈥 鈥 Sharon DeLay, President and Owner of BoldlyGO

6. Don鈥檛 say too much. 鈥淵ou should never say too much in a work email. Although tools like Slack help reduce the number of emails we receive in a day at work, there are still too many emails sent back and forth. Be concise in your emails and get to the point. I used to have a tendency to write emails that were too long and a boss taught me that it鈥檚 best to summarize information very quickly.鈥 鈥 Adena DeMonte, Head of Marketing, Reflektive

7. Don鈥檛 ask if it makes sense. 鈥淓mails are notorious sources of miscommunication. If you have to write, 鈥淒oes that make sense?鈥 in a work email, don鈥檛 hit send. Instead, reword the email until you鈥檙e confident that it does make sense, or else have the conversation in person.鈥 鈥 Kelli Newman, Head of People Operations at FabFitFun

8. Don鈥檛 lie. 鈥淩ecruiters have a sixth sense for honesty. For example, I once had a candidate cancel an interview at the last minute saying he鈥檇 gotten in a car accident 鈥 he even sent me a photo. It looked a little fishy to me so I looked it up and sure enough, it was pulled from the first page of a Google image search. Needless to say, we didn鈥檛 follow up with him.鈥 鈥 Rachel Bitte, Chief People Officer at Jobvite

9. Don鈥檛 pass the blame. 鈥淣ever say in a work email, 鈥楾hat鈥檚 not my problem.鈥 Not only is it unprofessional, but it also speaks volumes about how much you care (or don鈥檛) about the company鈥檚 success. In the workplace, it鈥檚 important to be a team player and problem solver.鈥 鈥 Dana Case, Director of Operations at
