Usually, I send to a client "Cover Letter" with phrase "May I get the details?", if I need to get more information about his project. Suddenly, I have discovered that it is not very polite. And now I can not understand - which phrase is best to polite and formal request for the information?
I found some variants:
Could you please give me the details?
Could I please get the details?
May I please get the details?
Do you mind if I get the details?
I can not decide which is best to use in this situation, and will be acceptable both in US and British English.
