Waiver coordinators at adventure parks, gyms and event venues know that collecting signatures is just the start. Once a participant signs up, you need their contact details to manage bookings, send reminders and follow up after the experience. Without a clear communication channel, participants miss sessions or forget renewal deadlines, and last-minute cancellations often go unnoticed until it's too late to find replacements.

Mobile Message connects to Otter Waiver through Zapier, so each new signee or check-in automatically captures their phone number and contact details. You can then text participants directly whenever a signup is confirmed, a booking reminder is needed or their next event is coming up. Automated SMS messaging keeps participants informed at every step of their experience, reducing no-shows and keeping your schedule full. Participants respond faster to text alerts than email, so your confirmations land when motivation is highest and your bookings stay solid.
