Business email etiquette rules and tips

Now, let’s talk about how you can perfect your email etiquette. Below are the most common rules to follow. 

  • Research about your recipient before emailing

Before getting in touch with your recipient, do some research to personalize the message you are going to send. No one would be pleased to see “Dear Sir or Madam” instead of their name in the greeting, especially when their email address contains the name.

Also, be aware that people from different cultures speak and write differently, and you need to be prepared for it. Those differences might be related to the word choice, tone, and even response times. For example, the Japanese might find it impolite if you introduce yourself via email without the involvement of a mutually respected third party.

  • Include a relevant subject line

People usually decide whether to open an email based on the subject line. Also, you need to understand that you aren’t the only one sending information to your recipients. That is why your subject line isn’t something you can take lightly. You need to make every effort to get the recipient to open your email.

However, keep in mind that lying or including misleading information isn’t the best option. Tricking the recipient into opening your email with the deceptive subject will just ruin your reputation.

Remember, people want the subject line to tell them what the message is all about. So make sure that there is no disconnect between the subject and the email content. 

Here are some good examples: “Meeting date changed,” “Suggestions for the report,” “ 55-point checklist for growing your audience on Instagram quickly.”

  • Use professional introduction

There are plenty of situations in which you may need to introduce yourself in email. Those include writing to new contacts, potential employers, customers, partners. In all cases, you need to sound confident and competent.

If you want to make a good first impression on your contact, it is better to avoid such laid-back expressions like, “Hey folks,” or “Hi guys.” When it comes to introductions, use your first name (or it can be both the first and last names) with some background info in the opening sentences of your email. For example, “Dear Mr. Jackson, My name is Cynthia Nixon, PR Director. I was referred to you by Ms. xxx.” 

  • Use a business email address

When you receive a new email, you probably check who the sender is. And if the message came from [email protected], chances are you won’t take it seriously even if there is something valuable for you inside. Just received an email from [email protected]? Well, that would make a big difference. 

  • Write in a pleasant tone

Hearing a person speaking in-person vs. reading a message on a screen can come off very differently. When sending business emails, it is better to avoid dry humor, sarcasm, or irony. This can lead to misinterpretation because the recipient can’t hear your tone of voice or see your facial expressions. Always be polite with unknown people, no matter who they are.

  • Keep your email brief

Try to limit your email to one topic per message. And keep it as short as possible. Maybe the recipient won’t read it on a typical PC screen, and it will take them ages to scroll down.

  • Pay attention to your font type and size

Keep your favorite lilac Comic Sans for your cousin’s birthday. When it comes to business correspondence, it is always better to use classic fonts, colors, and sizes. This will make your emails easy to read for other people. The best fonts are 10- or 12- point Arial, Times New Roman, Verdana, Calibri. As for color, black is the safest choice.

  • Use proper closing in your email

When the recipient finishes reading your email, they should find two things at the bottom. The first one is a sign off followed by your name. For example,

“Best regards,


And the second one is a professional email signature.

  • Include a professional email signature

Now, when you managed to hold the reader’s attention until the end of your email, provide them with essential information about you. A professional email signature can consist of your name, company name, contact details, website, photo, and any social networks.

  • Proofread every email you send

Don’t hope that your email mistakes will go unnoticed by the recipients. Always use good grammar and punctuation and check your spelling. But don’t rely on spell-checkers only. Proofread your email a few times, preferably aloud, before clicking the “Send” button. 

  • Try to reply fast and to all emails

It’s not always easy to reply to every single email you receive, but you should do that, as it serves as good email etiquette in business. Also, don’t make your recipients wait longer than 24 hours.

  • Keep confidential information in secret

Keep in mind that whatever you write, it can be forwarded to others. So, to be on the safe side, don’t discuss sensitive information in emails such as someone’s tax information or details of the huge transactions.

  • Check your attachments 

Always mention attachments in your email. If you are going to attach something large, it is better to ask permission (heavy attachments can clog the recipient’s inbox). Also, don’t send more than two attachments in one email, because Internet Service Providers (ISPs) may mark your email as spam before the recipient even gets to open it. On top of that, a lot of companies have a limit on size for incoming emails. So, it is better to use links (Google Drive, Onedrive, Sharepoint, etc.)

  • Use out-of-office replies

If you are going to be away from your email for longer than a few days, you need to use an out-of-office automatic reply. Otherwise, people may think you are impolite and even rude because of not getting back to them for so long.

Email etiquette basic mistakes you should avoid

We hope you find our business email etiquette tips useful, but don’t relax yet. We have compiled a list of the most common email mistakes below. Don’t let them cost you a valuable connection. 

  • Don’t use informal salutations

Salutations like “Hey folks,” “Yo man,” or “Hey bro” are a big no-no in professional emails even if the recipient seems to be very friendly. It is better to use “Hi” or “Hello” with a name. For example, “Hi Carrie.” Also, when addressing a larger group, you can use common email etiquette greetings such as “Dear all,” or “Hi team.” Or if you are going to contact two recipients, you can use two names. For instance, “Hello Luke and John.” 

  • Avoid humor, jargon, slang, or shortcuts

The tone you think you are using in your emails may not be what the recipient perceives. Choose your words carefully. 

  • Don’t forward every email

Always think twice before forwarding. Some emails aren’t intended to be forwarded (private or sensitive information).

  • Don’t use BCC in email

BCC (it is when a recipient can be kept hidden from other addressees) can lead to a seriously awkward situation. It is shady to lead someone to believe they are the only recipient when they are not. So it is very dishonest, especially if we are talking about email etiquette at work. If you absolutely must do that, use the “Forward” button.

  • Don’t be angry, rude, or negative

Never email people in the negative or rude form. If you have really bad news, use objective words to say about that. Also, you can always keep the news for live communication.

  • Don’t use emojis

You may choose to use some emojis in your emails (such as a nice smiley face, but remember that they look unprofessional and can’t take away the sting of a hurtful message. Pay attention that a lot of emojis look completely different on different devices and platforms.

  • Don’t use a lot of exclamation points and CAPS

Avoid typing in all CAPITALS. IT MIGHT SEEM AS IF YOU ARE SHOUTING. Also, be careful with exclamation marks if you don’t want to look unprofessional and too emotional for business.

  • Don’t add “Sent from my phone”

Many people think that it is an excuse to be lazy and not delete it before answering. It is always better to use a professional email signature.

Many people, at some point, send emails in haste or simply don’t care much about email’s influence on their reputation. However, such haste and carelessness might result in poor grammar, inappropriate humor or sarcasm, unclear requests, negative tone of the email, and more. That definitely doesn’t make you look professional in the eyes of recipients. 

In this article, we gathered the best email etiquette rules for business every professional should follow. Once you use them properly in your everyday email communication and get no reply, at least you know it is not because of your poor email etiquette.
