Case Study: Marquis Software achieves 43% reduction in parole no-shows with Sinch MessageMedia

SMS reminders study shows 43% reduction in parole no-shows for US probation officers

Marquis Software, a leading provider of offender management systems (eOMIS®), faced a persistent challenge: the Arkansas Community Corrections Agency was experiencing roughly a 20% rate of canceled and no-show appointments with parole/probation officers, risking supervision outcomes and wasting officer time. To address this, Marquis sought a trusted text messaging partner to integrate appointment reminders and confirmations into their platform and selected Sinch MessageMedia for its robust API and dependable support.

Marquis integrated Sinch MessageMedia’s text messaging API into eOMIS®, enabling automated one‑day reminder texts, ad‑hoc and mass messaging, and stored message threads. A randomized trial with 4,000 participants showed that a single text the day before an appointment reduced no-shows by 43%, and statewide rollout delivered consistent ROI—fewer missed appointments, reduced officer time wasted, and lower parolee violations—while opening new use cases like fee reminders, two‑factor codes, and volunteer recruitment.
