Here's why and how to fix it:
* Redundancy: "Please" and "kindly" are both polite requests, making their use together redundant.
* Awkward phrasing: "Find attached for your signature" is a bit clumsy.
Here are some better ways to phrase it:
* Formal: "Please find attached for your signature."
* Less formal: "Please review and sign the attached document."
* Specific: "Please review and sign the attached contract."
Remember to always tailor your language to the specific situation and your audience.
