What type of tone does this email convey, casual, or professional?

Email:
Hello,

Per your request, I have reviewed the ILP and made comments on the document as well. As it stands, the only sections you have to complete are the columns titled "After Implementation". The deadline for completion is this Friday at 2:50 pm. The rest of the document appears satisfactory and once you complete the ILP you can continue with the rest of your assignment. Thank you for reaching out to me.

Sincerely,
Mr. Boss
This email conveys a professional tone because it uses professional language and phrases not commonly seen in casual conversations. Some examples include "per your request", "satisfactory", and "as it stands". Additionally, the greeting ("Hello") and the closing ("Sincerely, Mr. Boss") convey a professional tone compared to casual greetings and closings.
