Incorrect: "Please find the attached file of your application letter for administration position?"
Problems:
* "of your application letter": This is redundant. The attached file *is* your application letter.
* "for administration position": This is also redundant. The context of the email already implies the position.
* Question mark: The sentence is a request, not a question.
Corrected options:
1. Formal: "Please find attached my application letter for the administration position."
2. Informal: "Attached is my application letter for the administration position."
Important note: Always personalize your emails. Instead of "Please find attached," consider:
* "I have attached my application letter..."
* "Please review my attached application letter..."
By making these small changes, your email will be more concise and professional.
