Common Mistakes Writers Make
Writers we work with often repeat these errors:
1. Overusing Formal Words
Using “kindly” in every sentence makes your email stiff.
2. Mixing Formal and Casual Tone
Example:
“Dear Sir, thanks a lot!” → inconsistent tone
3. Using Complex Words Unnecessarily
Simple is better. Avoid jargon unless required.
4. Forgetting Context
“ASAP” may sound rude if not used carefully.
5. Incorrect Closings
Ending with “Cheers” in a formal email can seem unprofessional.

1. Keep It Clear

3. Use Polite Requests
Instead of commands, use:
- “Could you please…”
- “Would you mind…”
4. Avoid Over-Polishing
Too many formal phrases can reduce clarity.
5. Use Standard Closings
