Report and Memo

I’m confusing with the format to prepare report /email On behalf of someone

**My role as a Consultant

Question 1
Prepare a report on behalf marketing director for presentation to the board

To:Board
From: Marketing director

OR

To: Marketing director
From: Consultant

Question 2
Draf an email on behalf of operation director to send to the CEO

To: CEO
From: Operation direction

OR should it be

To: Operation director
From: Consultant

Which one is the correct position should be written?

Thanks
