Every morning at 9:00, find the meeting room bookings that start in exactly 7 days.
Email each booker a short reminder with the room name, the location's address, the date, and the start and end time. Mention that they can change or cancel the booking in the app if their plans have changed.
Skip bookings created less than 2 days ago, since the member has only just booked. Write in the member's language and keep it under 80 words.
