“Respected Sir, I am writing this email to humbly request you to please do the needful regarding the same.” TalkDrill, an Indian company that teaches workplace English, uses this sentence as its example of an email to fix. Its corrected version opens with the point: “I have attached the revised vendor contract for your review.”
Some sample leave applications for Indian schools open with “Respected Sir,” give the reason, and end with the request: “Kindly grant me leave for these two days.”
