LINE and SMS reminders
Check which notifications Business Box can send through LINE, email and SMS, and choose the channels your customers use.
Automated appointment reminders are sent by email, not LINE or SMS. The Paid plan includes LINE booking and confirmation, change and cancellation messages through a connected Official Account.
Choose the right notification channel#
Some customers check LINE more often than email. Explain how they will receive their booking confirmation and appointment reminders so they know where to look.
Ask customers to use an email address they check regularly for appointment reminders.
What email reminders include#
Booking emails include the appointment details, a calendar invitation and a link to reschedule or cancel within your rules.
Delivery failures are also visible: a booking whose confirmation was refused is flagged and you are told, so you know to reach the person another way. When email does not arrive
Use calendar invitations#
When a booking is written to your Google or Outlook calendar, the customer is added as a guest and the provider sends its own invitation. The appointment then sits in their phone's calendar with its own alert, which for many people is more effective than any reminder message.
Send additional messages when needed#
You can send a reminder manually through your own LINE account when a customer needs an additional message. Automated appointment reminders from Business Box remain email only.
Set up LINE booking and confirmations#
Add your booking link to a LINE rich menu or greeting message. With LINE integration configured, customers can book inside LINE and receive confirmation, change and cancellation messages from your Official Account.
And ask for a phone number#
Add a phone number question to the booking form for appointments where you would want to reach somebody quickly. It is on the booking when you need it. Booking form questions
