SMS Messaging
1. Enabling the Service
SMS messaging is enabled upon request.
- Cost: 3¢ per text message sent
- Activation: Once enabled by our team, a new SMS section will appear under Notification Setup
2. Configuring the Automated Reminder
In Notification Setup → SMS, you can configure:
- Enable Reminders: Check the box to activate automated SMS reminders
- Custom Message: Enter your preferred reminder text
- Timing: Set how far in advance the message should send (e.g., 24 hours or 2 hours before the appointment)
⚠️ Character limit: Messages are limited to 160 characters — this includes macros (e.g.,
$(TIME)on$(D_MEDIUM)) after they've been expanded into full text, not their shorthand length.
3. The Participant Experience
Participants are not automatically enrolled in SMS reminders. During booking, they'll see an opt-in checkbox to request a text reminder.
If they check the box and provide a mobile number, their reminder is automatically queued for the time you've configured.
4. Sending Reminders "On Demand"
For manual blasts — e.g., a last-minute schedule change or weather delay — send directly from the Appointments List page:
- Filter your list by Event or Date.
- Select the participants you want to reach.
- Click Send SMS and broadcast your message.
Note: This only reaches participants who originally opted in to SMS notifications — it won't reach anyone who didn't check the box during booking.
SMS Best Practices
Keep it brief. With only 160 characters, focus on the essentials: Who, When, Where.
Example message:
Reminder: Your appointment is at $(TIME) on $(D_MEDIUM) at the $(LOCATION). Please arrive 5 mins early.
