Answer:
This is a very good, polite e-mail sent to a colleague which will develop the professional relationship and personal friendship well in the long term.
Explanation:
1st of all, the email is written in request form and not in ordering form. This is most suitable when it comes to communications between same-level peers in an organization.
Then, we can see Rajiv, the sender is in a hurry to obtain the approval from Sandra but he is very careful not to offend her in any way verbally. Moreover, rather than just telling her to do it "As soon as possible", Rajiv explains why it is better to do it quickly.
In addition, Rajiv has made this email as a two way communication mode. He has given the opportunity to Sandra to inquire him if she has any questions which is a very polite thing to do!
Lastly, the email contains exactly the information Sandra had asked for. Sending the exact information requested by another party is a very good characteristic of good email etiquette.
