Booking reminders and email notifications
No-shows are the most expensive problem in appointment businesses — so bookings can now remind themselves. Pick a window under Settings → Apps → Reservations → Remind customer before their booking (1 to 48 hours) and every confirmed booking sends the customer one automatic reminder ahead of their start time. Speaking of channels: email joins WhatsApp, and you now choose how customers hear from you. Two switches in settings — Notify customers via WhatsApp and via email — set your defaults, and the confirm dialog shows a checkbox per channel so you can decide differently for any single booking. Email is free; the booking form has an optional email field, and customers who fill it in get their confirmations, updates, and reminders in their inbox — with replies going straight to you.
