Well I don't understand this Email but I think its an answer for an information you sent to him so he want to know to be sure in what you sent to him (I think) this is what I understand :) so I think its polite.
actually, I posted this photo for some one correction. Coz, I have no experience write email in English. I don't know, is it polite email or arrogant. Please some one correction. Thank you for your kindness
