You can automatically add instructions for your clients to confirm an appointment by replying to text reminders or by clicking the Confirm button in email reminders.
To do this, follow these steps:
Go to Settings > Reminders.
In the "Confirm, Reschedule, and Cancellations" section, click the checkbox to Add confirmation instructions to reminders.
Optionally, you can stop succeeding reminders if a customer has already confirmed an appointment after getting a reminder.
You can also enable and get text or email notifications when a customer confirms an appointment.
Click Save.
If your client replies with C to a reminder message or clicks the Confirm button in an email reminder, the appointment will be marked as confirmed in your GoReminders calendar.
If your customer replies with any other message, you will see their reply on the Messaging tab. If a customer replies to a reminder message, you will receive a text or email if you enable notifications on the Reminder Settings page.
