I wanted to inform you that I will be on leave tomorrow, [date], due to [mention reason briefly if necessary, e.g., personal reasons/family commitment]. During my absence, [mention who will cover your responsibilities if applicable, e.g., "John will be handling my tasks in my absence"].

Please feel free to reach out to [mention alternative contact if necessary, e.g., "John or Jane"] for any urgent matters that may require immediate attention. I will have limited access to emails during this time but will respond as soon as possible upon my return.
