25 Email Etiquette Tips for Professional Communication


You probably send dozens of email a day, but are your messages well received? Are some of your emails just ticking people off? It could be you are breaking some cardinal rules of business email etiquette.

Our editorial team gets and sends hundreds of emails a day. We’ve seen the good, the bad and the ugly. So, we’ve come up with email etiquette guidelines that business people should follow for solid email communications.

Business Email Etiquette Guidelines

Here are 25 email etiquette guidelines you may wish to consider for your own small business.

Get the Salutation and Closing Right

Writing effective emails starts with the proper salutation and closing. A Perkbox Insights survey of 1,928 professionals found there is a real preference for certain email greetings and closings versus others. Almost half of those surveyed prefer emails that start with the greeting “Hi”. Other popular greetings include:

  • Good morning/afternoon (48%)
  • Hello (21%)
  • Dear (20%)

When it comes to closing expressions for business emails, survey respondents preferred the following:

  • Kind regards (69%)
  • Thanks or thanks again (46%)
  • Regards (31%)
  • Thanks in advance (21%)
  • Best wishes (20%)

And what is the worst way to end business emails? “Love”, “Warmly”, and using no sign-off rated the worst ways to close.

Don’t Leave People Hanging

Confirm receipt for messages you can’t get to right away. Let the sender know that you got it and will respond at a later date. Tell them when to expect it. Set a date and time and stick to it.

When you go on vacation or out of the office for more than a day or two, set up an out-of-office reply or away message so people will get a prompt response, ensuring they are not left wondering. Include the date you’ll be back in the office and when you expect to respond. Give people an alternate contact for urgent matters in case they need to reach someone in your company right away.

Limit Acronyms and Jargon

Before using business abbreviations, acronyms, or jargon in your emails, assess the familiarity and understanding of your audience. Consider the knowledge of the recipient. If you’re dealing with clients in different industries, for example, you might want to include more information than you would with your co-workers. Overusing acronyms can alienate or confuse participants, reducing clarity.

Only Use ‘Reply All’ When Necessary

When you get emails that include several people, you might be tempted to just reply to everyone. Consider the relevance of your response to all recipients before doing so. But this can lead to a lot of wasted time for recipients if the message isn’t relevant to them.

It can even be embarrassing if your reply conveys sensitive company information and it goes to a client who happens to be copied. Assess the necessity and potential impact of your message. So use care and only hit “reply all” when it’s absolutely necessary.

Use the Undo Send Feature

Some email clients like Gmail have a feature that allows you to undo sending an email for up to 30 seconds. This gives you a brief window to reconsider or rectify any mistakes that can cast a long shadow if you breach email etiquette.

If you forgot to check for typos or an attachment, or if you have second thoughts about the content or tone of your message, act quickly and you can cancel sending the email before it arrives at the other end, preventing potential misunderstandings or the need for follow-up explanations. Utilize this feature wisely to ensure your communications are accurate and convey the intended message.

Wait 24 Hours Before Sending Emotional Messages

If you ever find yourself in a situation where you are tempted to send an angry or emotional email, craft your message. Pause and reflect on the potential impact. Avoid hitting send until you step away for a day to clear your head.

This pause allows for a calmer perspective. Work-related emails should be devoid of negative emotion. It’s painful for others to receive emotional words and can lead to unintended consequences.

Avoid Using All Caps

Don’t go crazy with the CAPS LOCK as 67% of people can’t tolerate it according to the survey. This type of message is perceived as shouting, which is often unwelcome. Always use sentence case.

Capital letters can add emphasis. But they can also come across as screaming, alienating your audience rather than engaging them. Consider using italics or a color to highlight key points without overwhelming readers.

Keep it Short

About 29% of people say they can’t tolerate long emails. Do you really want to lose almost a third of readers just because of message size? Respect the time of your team and business associates. Use short paragraphs and formatting such as bullet points that make emails easy to skim.

Instead of a long email, try an alternative: a video call, face-to-face meeting, or phone call. If it has to be in writing, create a separate report in an attachment or shared cloud document.

25 Email Etiquette Tips

A Clear Subject Line is a Must

Subject lines should accurately reflect the content. A clear subject line is a courtesy that informs the recipient what to expect before opening your message.

More than that, it may make the difference between people opening your email or ignoring it, ensuring your communication is timely and effective. An ambiguous subject can delay response times.

Don’t Share Confidential Information

Emails are all too easy to forward and share, or to accidentally send to the wrong person, making them a risky choice for sensitive content.

Most email messages are not the right format to share confidential information as they lack the security measures necessary to protect such data, underscoring the importance of using secure, encrypted channels for sensitive exchanges.

Use Humor with Caution

You might be tempted to add a little fun or humor to your emails. But without body language, humor and tone can be difficult to decipher in emails, potentially leading to misunderstandings or offense.

Never use jokes unless you have a good relationship with the recipient and are certain they will appreciate the humor, ensuring your intent is clearly understood.

Limit Emoji and Emoticons

When it comes to emoji, smileys, and emoticons, keep those to conversations with friends and close co-workers where the context and relationships support their use.

Customers and sales prospects may see them as unprofessional or too casual for business communications, potentially undermining your message’s seriousness or professionalism.

Don’t Be Hasty with Reminders

Give a recipient a day or two to respond, depending on the type of inquiry. A recipient may feel chastised by getting a reminder when he or she has been out of the office or in meetings all day.

Also, before sending reminders, please check your junk or spam folder. Put yourself in the recipient’s shoes. Has anyone ever complained they did not receive one of your messages, forcing you to go out of your way to re-send it, only to then reply “Oh, it was in my spam folder.” You probably felt slightly annoyed, thinking, “Why didn’t you look there in the first place?”

25 Email Etiquette Tips

Be Careful with BCC

BCC stands for blind carbon copy and it means that others do not see the blind-copied person on the recipient list. BCC is good etiquette if you want to inform other people in your organization and protect their name, title or email address from going to, say, a sales rep for an outside vendor. But BCC can be bad etiquette if your purpose is to be devious and go behind a coworker’s back. How will you feel if your coworker learns that his boss was blind copied? If it could upset him, then don’t use it.

Add a Personal Message When Forwarding

When you need to forward an email to a coworker, add an introduction at the top instead of just hitting send. This personal touch can clarify the relevance and ensure the recipient understands the context.

Don’t force associates to read through an unfamiliar email thread without context. Also, consider changing the subject line title so it makes more sense and directly relates to the current discussion or task at hand.

Add the Email Address Last

If you’re drafting a brand new email, start with the subject and content before adding email addresses. This will prevent you from accidentally sending it too early and having to waste everyone’s time telling them to ignore your incomplete message.

Have a Clear Call to Action

What do you want the recipient to do with your message if anything? If it’s purely to inform the other person, then so state. But if you expect a reply, a decision or another thing, be crystal clear. It’s amazing how many emails are vague about what the recipient is being asked to do (or not do).

Include Contact Information

Twenty-three percent of email users say it is poor etiquette to not have an email signature block. A professional email signature with relevant information doesn’t just make you look more professional; it also makes it easier for the person you’re contacting.

Include relevant information like your phone number, company website, and social media handles so they can easily reach out if they have extra questions. If your email includes specific instructions for a person to call you or contact you in another way, include those details in the body as well.

25 Email Etiquette Tips

Stick to Black and White

Some individuals try to add some pizazz to their emails with unique colors, fonts, or design elements. But this can rub some recipients the wrong way. And the styles that appeal to you may make it less appealing to others.

Avoid using unique font colors and background patterns in your emails. Classic black and white is the easiest to read. And pair it with basic fonts like Times New Roman. This can help you make a professional impression, whether you’re communicating with employees or partners. .

Limit Exclamation Points

Some use exclamation marks to show excitement or convey friendliness. However, they should be used sparingly in professional email. In fact, 16% say this punctuation mark is unacceptable while 48% will tolerate only one per email.

Keep in mind the tone of the email. For example, an email announcing exciting new products or services may accommodate more than an email about an employee communication issue. And then read through it at the end to double check that it’s not packed full of excess excitement.


You don’t want to take the time to craft a great email message only to have it littered with spelling and grammar mistakes. Take a minute to proofread and spell check before sending so you can catch any potential errors. Look for both spelling and grammatical issues.

Additionally, read through your message with a mind on how your recipient will read it. Think about the tone to make sure it doesn’t get taken in a different way.

Then go back and make sure that you spelled the person’s name correctly in your email. You can’t be too careful in this instance. Also choose the proper email address — it’s embarrassing to send to the wrong email accounts.

Know When to Be Formal

Keep things more formal with those you’re emailing for the first time. Err on the side of being more formal and professional with clients and superiors as well. Formality shows respect and is less likely to be misinterpreted.

Once you get to know someone more, you can get less formal. For instance, you might use first names or a nickname instead of full names. Or you could shorten your greeting or sign off with those you communicate with regularly.

Don’t Forget to Attach

It’s fairly common to say you are attaching something and then forget to actually do it. This doesn’t just make you look forgetful; it also forces the recipient to reach out with a reminder. So double check before sending.

Additionally, name your attachments appropriately if there are several. This allows them to avoid opening each one to see what it is. And it can even help them avoid opening attachments with viruses or malware. If possible, send PDFs instead of files that require a specific program so they don’t need to download extras to see what you’ve sent.

Consider Different Cultures and Languages

You might sometimes correspond with individuals from different cultures or backgrounds via email. So be sure to consider that when crafting your responses so no one gets offended or confused.

For example, use simple, widely recognized terms instead of American-centered slang. If you regularly communicate with teams or recipients in a particular country, research info about that culture to get even more specific and avoid miscommunication.

Start a New Email Chain for New Subjects

When emailing someone who you correspond with frequently, it can be tempting to keep just one chain going continuously. But this can make it difficult to keep your conversations organized. So start a new chain for each new subject.

Along the same lines, only forward messages when absolutely necessary. And avoid hitting reply all when you only need to message one or two recipients on an email chain.
