6 rude emails you might be sending without realising

There’s no doubt about it, email is essential in our daily work. It’s fast, efficient, and keeps teams connected across departments and even countries. But without facial expressions, body language, or tone of voice, even a well-intentioned message can be misunderstood. Misinterpretation can affect relationships and delay work. 

With guidance from Ku Sim Ling, Human Resources Expert, affectionately known as AuntyHR, you can sidestep common email pitfalls and become a more effective communicator. 

Common Email Mistakes 

1. Skipping the Pleasantries 

A proper greeting and sign-off set the tone. Skipping them may seem minor, but colleagues can perceive it as abrupt or impolite. 

AuntyHR says, "You wouldn’t start speaking to someone in a meeting without a hello, so don’t do it in an email." She adds, "Even a simple ‘Hope you’re well’ goes a long way in showing courtesy and maintaining professional rapport." 

2. Marking Emails as ‘Urgent’ 

Truly urgent matters deserve attention, but using ‘urgent’ in the subject line can feel like a demand and may put colleagues off — or even get overlooked. 

AuntyHR explains, "Email is the easiest thing to ignore. Urgent matters are often better handled with a call, chat, or face-to-face discussion." She adds, "So before sending an ‘urgent’ email, consider which channel will be most effective." 

3. Saying “Thanks in Advance” 

While polite, this phrase can imply you expect agreement before the recipient responds. 

AuntyHR notes, "People may think, ‘I haven’t said yes yet, why are you thanking me?’ It can feel presumptive." She adds, "Ask first, then thank them once they’ve agreed." 

4. Copying Too Many People 

Overusing CC creates clutter and can reflect poorly on professionalism. Copying multiple agencies or unnecessary recipients may also expose sensitive information. 

AuntyHR advises, "Only copy colleagues if they have an action, responsibility, or oversight role. Otherwise, keep the audience tight." 

5. Information Overload 

Long, dense emails can overwhelm readers and obscure your message. 

AuntyHR advises, "Before sending, ask yourself: what is essential? What does the recipient really need to know?" She adds, "Keep it concise and use bullet points if needed. People can only absorb so much at once, so stick to the rule of three: limit each email to three key points on the same topic. Anything more should be sent in a follow-up or discussed via a separate channel." 

6. Poor Grammar or Inaccurate Information 

Even small errors can undermine credibility and professionalism. 

AuntyHR says, "Attention to detail shows respect for the recipient. Always proofread before sending." She adds, "If you use tools or artificial intelligence (AI) to help you draft your email, it’s your responsibility to review and edit the output. The AI won’t look bad for making the error, but you will." 

Writing Effective, Professional Emails 

“To ensure your emails are clear, actionable, and professional, focus on structure and on making your emails resonate with recipients,” says AuntyHR. 

Email Structure Tips 

• Be Clear and Focused 
  Start with a subject line that accurately reflects the email’s purpose, and limit your email to three key points per topic. For example: “Project X: Feedback Required by Friday” is better than “Update.” 

• State Actions Explicitly 
  Who needs to do what, and by when. Avoid vague requests like “please look into this”; instead, use “Please review the attached document and provide comments by 3 pm Wednesday.” 

• Include Your Signature 
  Always add your name, position, and preferred contact method so recipients know how to respond or follow up. 

Tips to Resonate with Recipients 

• Consider Your Audience 
  Tailor tone according to hierarchy and relationship. Spell out acronyms on first use, don’t assume everyone knows them. For example: “Close of Business (COB)”, “For Your Information (FYI)”, or “Human Resources (HR)”. 

• Respect Their Time 
  Keep emails concise and to the point. Avoid unnecessary CCs, long introductions, or repeating information the recipient already knows. Use short paragraphs, bullet points, and highlight key information. Malaysian inboxes are often crowded with emails, updates, and awareness messages, so make your message easy to skim. 

• Mind Language Choice 
  Avoid switching languages unless you are certain the recipient is comfortable; sudden changes can confuse or exclude them. 

AuntyHR adds, “By knowing what to avoid, structuring your emails clearly, and making them resonate with recipients, your messages are more likely to be read, acted on, and leave a positive impression.”
