How to Set Up Text (SMS) Reminders for Participants
Keep Volunteers and Participants in the Loop with a Quick Text
Last Updated June 17, 2026
SMS reminders are available for Premium, Campus, and Organization Plan members in the US, Canada, and Australia. Participants opt in to receive text reminders in addition to email — standard carrier charges may apply.
For New SignUps
Participants are automatically prompted to opt into text reminders during the sign-up process. They can choose to receive texts, emails, or both. Reminders default to 2 days before their assignment but can be set anywhere from 1 to 7 days out.
For Existing SignUps
New participants joining an existing SignUp will see the text reminder prompt automatically. Participants who are already signed up will not be prompted automatically — you need to invite them to opt in.
To do this:
- Go to the Messages tab in your Organizer view.
- Select Signed Up participants.
- Send a message directing them to My Info to enter their phone number and enable text reminders. On desktop, they will find My Info via the head/shoulders icon; on mobile, via the three-bar menu.
