Email Etiquette: 10 Rules For Writing Professional Emails

Navigating the world of email etiquette can feel like walking a tightrope. Are your emails too formal? Not formal enough? Did you accidentally "Reply All" to something meant for one person? 😬 

Mastering good email etiquette isn’t just about avoiding awkward moments—it’s about building stronger relationships with clients, colleagues, and prospects.

In this guide, we’ll break down what email etiquette is, why it matters, and the essential rules to follow. Plus, we’ll share practical email etiquette examples and ready-to-use templates to help you craft emails that get results. 

Email etiquette refers to the set of guidelines for writing, sending, and responding to emails professionally and respectfully. It makes sure your communication is clear, polished, and well-received.

Think of it as the modern equivalent of table manners—simple rules that leave a lasting impression!

Mastering proper email etiquette benefits your business in three key ways:

• It helps you seem professional: Every email you send represents you and your business. Sloppy emails can make you seem unorganized or careless, while polished ones show that you’re reliable and respectful.
• It fosters mutual respect: Polite and structured emails avoid misunderstandings or friction. When your communication is thoughtful and considerate, it inspires goodwill and encourages stronger, more productive partnerships. 
• It builds trust and strengthens relationships: Good communication lays the foundation for long-term success. Mastering email etiquette isn’t just about avoiding mistakes—it’s about building connections and making your communication more impactful.

Now that you know what email etiquette is and why it's important, let's dive into the nine rules to follow when crafting your emails.

The tone and style of your email should reflect your recipient’s expectations. Think about their role, preferences, and industry norms. A tech start-up CEO might appreciate casual, exclamation-point enthusiasm, while a lawyer might expect concise professionalism.

Examples:

• Casual: “Hi Jamie, just wanted to follow up on our brainstorming session—your ideas were spot-on!”

• Formal: “Dear Ms. Roberts, I hope this email finds you well. I’m reaching out to follow up on our conversation regarding contract updates.”

A subject line can make or break your email’s chances of being read. Keep it direct and action-oriented. 

Example:

• Effective: “Meeting recap”
• Not-so-effective: “Hey there! A couple of quick thoughts I wanted to share from our meeting”

Typos can make your email seem rushed or unprofessional. Always check grammar, spelling, and your recipient’s name before you click "Send." Also, double-check the email addresses to ensure you're sending it to the right person, and use "Reply All" only when it’s truly necessary.

Example: 

• Instead of: “Pleese see attched document.”
• Try: “Please find the attached document. Let me know if you have any questions!”

Generic emails rarely get attention. Address the recipient by name and mention specific details to show you’ve put thought into your message.

Example:

• Instead of: “Thanks for your time.”
• Try: “Thanks for your time, Mia! Your suggestion to improve scheduling by offering flexible slots was fantastic.”

Emails don’t benefit from tone of voice or body language. Keep your tone neutral and your instructions clear to minimize confusion. 

Example:

• Avoid: “We NEED this ASAP!!!”
• Use: “Could you review this by EOD tomorrow? Please let me know if that timeline works for you.”

Another tip? Stop using abbreviations commonly used in text messages! While “lol,” “plz,” or “g2g” might be appropriate and understood via text, they can come across as unprofessional or confusing in emails. Instead, stick to full words and proper grammar to maintain clarity and a polished tone.

Example: 

• Avoid: "Hey, can you plz send me the doc? Thx!"
• Use: "Hi, could you please send me the document when you have a moment? Thank you!"

Taking the time to fully write out your thoughts shows respect for the recipient and ensures nothing gets lost in translation.

Don’t assume the recipient will notice you’ve attached a file—highlight it in the email body.

Example:

• “Attached is the proposal for your review. Please share your feedback before Friday.”

End every email with a clear action step to guide the recipient. Whether you want a reply, feedback, or a meeting booked, make the ask explicit.

Example:

• Weak: “Let me know what you think.”
• Strong: “Could you share your feedback on this draft by Thursday?”

If an issue hasn’t been resolved after three back-and-forth emails, it’s time to switch gears. Instead of continuing a long email thread that wastes time and causes confusion, pick up the phone or schedule a meeting.

To avoid even more back-and-forth messages trying to find a time to meet, add a booking link to your email! That way, the recipient can go on and choose a time that works for everyone in seconds, without the endless email chains.

Timing is everything when it comes to email etiquette. Even the most polished email can go unnoticed if it’s sent at the wrong time.

Best practices for timing your emails

• Send during business hours: Aim for 9 AM to 3 PM, when people are actively checking their inboxes. Late-night or early-morning emails can come across as intrusive.
• Tuesdays, Mondays, and Thursdays are the most effective days for engagement, according to research by Hubspot. Avoid weekends, especially Sundays, when emails are likely to get ignored.
• Double check timezones: Double-checking time zones means your emails land when they’re most likely to be seen, turning good timing into great opportunities.
• Reply promptly: Timing isn’t just about sending emails—it’s about responding too. Reply within one business day to keep conversations moving and build trust.
  
  Can’t reply quickly because you’re out of the office? Set up an automated OOO (out-of-office) reply to let others know when they can expect a response and who to contact in your absence! 

Remember—timing your emails thoughtfully ensures your message is not only read, but acted upon.

Bonus rule. Proofread. Again.

One more time for the people in the back!
