What this helps you do
Section titled “What this helps you do”Need to warn participants about a last-minute schedule change, a weather cancellation, or just send a friendly reminder? Bulk SMS lets you message all participants in a session directly from the Agenda. Write a freeform message or use a template with merge tags that auto-fill each participant’s name, session details, and your school name.
Before you start
Section titled “Before you start”- A session exists on the Agenda with at least one participant who has a phone number
- Your school has SMS credits available (the balance is shown at the bottom of the SMS panel)
1. Open the session context menu
Section titled “1. Open the session context menu”On the Agenda (Activity Agenda view), click the three-dot menu (⋮) on the session block you want to message.
2. Click “Send SMS”
Section titled “2. Click “Send SMS””Click Send SMS from the dropdown. A slide-in panel opens on the right side titled Send Message.
The panel header shows the session date, time, and product name (e.g., “10/03/2026, 08:00 | Course”).
3. Choose when to send
Section titled “3. Choose when to send”Under SCHEDULE, select one of:
| Option | Description |

- Participants without phone numbers appear but cannot receive SMS
5. Write the message
Section titled “5. Write the message”Choose between two message modes using the tabs below the participant list:
Free text — Write a custom message from scratch in the text area.
Template — Use the default template with merge tags that auto-fill per recipient:
| Merge tag | Replaced with |
|---|---|
firstname | Participant’s first name |
product_name | Product/activity name |
session_date_time | Session date and time |
school_name | Your school/business name |
