6 rude emails you might be sending without realising

Email is the core of modern professional communication, but simple errors in tone, structure, or etiquette can unintentionally make you appear thoughtless, demanding, or unclear. Even minor slips can detract from your credibility. 

We spoke with Ms. Elizha Corpus, an HR Consultant specializing in culture transformation who outlines six common email habits to eliminate to ensure your written communication is always concise, respectful, and effective. 

1. Skipping the Respectful Greeting 

It might feel efficient to jump straight into the request, but skipping basic pleasantries can feel abrupt or dismissive. “In many professional settings, showing respect is expressed through warmth,” says Corpus. A simple “Good day” is professional and sufficiently respectful. Corpus suggests, “Adding a short, situational well-wish like ‘I hope you’re doing well’ or 'I hope you’re safe given the weather' during holidays or local events. These small touches feel natural and build goodwill. 

2. Marking Everything as 'URGENT.' 

Frequent use of the "urgent" flag for non-emergencies can signal a lack of ownership or an expectation that everyone should drop their tasks for you, which can be seen as inconsiderate of a colleague's workload. Corpus suggest to clearly explaining the timeline in the subject or opening line to convey urgency respectfully. “For example, use, ‘For Review Today: (topic)’ or “Action Required by 3 PM: (topic).” This conveys urgency while showing respect for the recipient’s schedule.” 

3. Overusing Softeners or Hedging Language 

“Using phrases meant to avoid sounding pushy can actually dilute the clarity and accountability of your message,” says Corpus. “Cut Phrases like, ‘Maybe we can,’ ‘I think we should,’ or ‘If it’s okay, we can…’”.  

Her expert advise is to shift to collaborative but assertive phrasing to ensure clarity. 

Instead of: "Maybe we can finalize the presentation soon." 

Use: “May I suggest we finalize the report by Friday so we can review it before submission?” 

Instead of: "If it’s okay with you..." 

Use: “Would you be open to…” 

This balance of diplomacy and assertiveness is key to effective professional requests. 

4. Information Overload 

Long, dense emails can overwhelm readers and obscure your message. Before sending, ask yourself: What is essential? What does the recipient really need to know?  Corpus advises, "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." 

5. Copying Too Many People (The CC-All Habit) 

Including a large list of recipients can signal a lack of ownership or confidence in your message, as if you are attempting to shift accountability to others. “Only include people who are directly involved in the task or the decision. If you must CC someone for visibility, clarify your intent: ‘CC’d (Name)for awareness.’” Corpus advises. This practice helps maintain accountability and keeps the main conversation streamlined for those acting. 

6. Making Avoidable Grammatical Errors 

Minor grammatical or formatting errors immediately detract from professionalism and can make an email sound less polished. A common error is the "double past tense" (e.g., "Did you finish it?"). 

Corpus stresses the importance of proofreading aloud: "If it doesn’t sound natural when spoken, it probably needs a light edit. Pay special attention to verbs following 'did' or 'didn't,' ensuring they are always in the present tense format.” For high-stakes emails, such as those sent to executives or for job applications, use AI for the initial polish, but always perform a final manual review yourself. Or better yet, have a trusted peer take a second look to ensure the tone is just right. 

Ultimately, professional email etiquette is about balancing directness with warmth. A short, genuine thank-you line at the end of your message also goes a long way in building and maintaining a healthy relationship with the reader. By being mindful of these subtle habits, choosing clarity over overload and personal responsibility over automated drafts, you ensure your digital presence is as polished and professional as your work.
