Email Etiquette Rules with Examples by Chase Dimond

You know that feeling when someone cuts in line at the grocery store? Or when someone chews with their mouth open? It’s annoying because they are breaking the unwritten rules of being polite.

Well, the internet has those rules too. We call it email etiquette.

It sounds like a fancy term you would learn at a boarding school, but it is actually very simple. It just means not being rude in your inbox.

Whether you are emailing a teacher, a boss, or a potential client, how you write changes how they see you. A messy email makes people think you are messy. A clean, polite email makes you look smart and organized.

Here is a simple breakdown of the most important email etiquette rules to keep you out of trouble.

Why Should You Care?

You might be thinking, "It's just an email, who cares?"

But think about it this way: in a text message to your friend, you can be sloppy. But in the professional world, your email is like your outfit. You want to look sharp.

Even if you are in a rush and accidentally type email edicate into Google instead of "etiquette," the goal is the same. You want to know how to act right so people respect you.

The Subject Line is the "Knock on the Door"

Imagine walking into your boss's office and just staring at them silently. That is what an email with no subject line feels like.

The subject line tells people what to expect before they open the message.

  • Bad idea: "Hey" or "Question" or leaving it blank.

  • Good idea: "Meeting notes from Tuesday" or "Question about the math homework."

Be specific. It helps the other person know if they need to open it right now or if it can wait.

Say Hello (Like a Real Person)

You wouldn't walk up to a stranger and just start shouting a list of demands. You would say "Hello" first.

One of the easiest email etiquette examples to follow is using a proper greeting.

  • Safe bets: "Hi Sarah," "Good morning Team," or "Dear Mr. Smith."

  • What to avoid: "Yo," "Hey guys" (if it's a formal boss), or just starting with the first sentence.

Don't Write a Novel

People are busy. They don't have time to read five paragraphs about your weekend.

Get to the point. Tell them who you are, what you need, and why it matters. If your email is shorter, you are more likely to get a reply.

If you have a lot to say, try using bullet points. They are easier to read than big blocks of text.

The "Reply All" Trap

This is the most dangerous button on your screen.

Let’s say your boss emails 20 people to say, "The office is closed on Friday."

  • Do: Reply to your boss saying "Thanks."

  • Don't: Hit "Reply All" to tell 20 coworkers "Thanks."

When you hit "Reply All," everyone gets a notification. If 20 people do it, that’s 20 annoying buzzes in everyone’s pocket. Only use "Reply All" if everyone really needs to see your answer.

Watch Your Tone

Text is tricky. You can't see someone's face or hear their voice. A joke can sound mean, and a short sentence can sound angry.

To practice proper email etiquette, always be a little more polite than you think you need to be.

Avoid typing in ALL CAPS. It looks like you are yelling. And be careful with sarcasm, as people might take you seriously.

The Attachment Check

We have all done it. We write, "I have attached the file below," and then we hit send without attaching anything.

It’s a classic mistake, but it makes you look a little scattered.

A good trick? Attach the file before you write the email. That way, you can never forget it.

How to Say Goodbye

Just like you need a greeting, you need a sign-off. It’s the digital handshake at the end of the meeting.

  • Professional: "Sincerely," "Best regards," or "Thank you."

  • Friendly: "Best," or "Talk soon."

Make sure your name is at the bottom so they know who sent it.

Reply in a Decent Time

You don't have to reply five seconds after you get an email. But try not to wait five days.

A good rule of thumb is 24 hours. If you need more time to find an answer, just send a quick note saying, "I got your message and I am looking into it." That way, they know you aren't ignoring them.

Final Advice

You don't need to memorize a giant rulebook to be good at this.

Just treat the other person with respect. Be clear, be polite, and proofread your message once before you hit send. If you do that, you are already doing better than most people.
