The Perfect Email Structure
Every professional email follows this 6-part structure:
Subject Line
Be specific and concise. Avoid vague subjects like "Hello" or "Question".
Greeting
Use "Hi [Name]" for most business emails. "Dear" for very formal contexts.
Opening Line
State your purpose immediately. Don't start with lengthy pleasantries.
Body
Keep paragraphs short (2-3 sentences). Use bullet points for lists.
Closing
End with a clear next step or call to action.
Sign-off
"Best regards" works for almost everything. "Thanks" for casual.
8 Email Mistakes Non-Native Speakers Make
These patterns make your emails sound unnatural. Here's how to fix them:
Starting with "I"
Get to the point. You don't need to announce that you're writing an email.
Using "Please revert"
"Revert" means to return to a previous state, not to reply. This is a common error in South Asian English.
Too many pleasantries
One brief pleasantry is fine. Multiple ones waste the reader's time.
Using "Kindly"
"Kindly" sounds outdated. "Could you please" is more natural and professional.
Wrong formality level
Business emails should be friendly but professional. Avoid slang and excessive punctuation.
No clear action
Always tell the reader what you need them to do and by when.
Apologizing too much
Replace excessive apologies with gratitude. It sounds more confident.
Using "ASAP"
"ASAP" sounds demanding. Give a specific deadline instead — it's clearer and more respectful.
Matching Your Tone
The same message can be written casually, professionally, or formally. Use the right tone for your audience:
Requesting information
Declining a request
