Every embassy publishes estimated processing times on their website. If the official timeline is "15 business days" and you are only on day 10, do not email the embassy. They will likely reply with a generic automated response telling you to wait. Only email if your application has exceeded the standard processing time.
Thank you for your time and essential service. Sincerely, [Your full name] [Phone number with country code]

Keep it brief. State that the standard processing time has elapsed and you are kindly requesting an update to finalize your travel arrangements (flights, accommodation, etc.). E. The Closing
Please advise if any additional documents are required from my end to facilitate the completion of processing.
