Built into your platform, not another app for volunteers to download

Volunteers don't check email between shifts. A rostering reminder buried in an inbox gets missed, and a gap on the roster is hard to fill at short notice. Australian volunteer management platforms use Mobile Message's API to send welcome texts to new sign-ups, remind rostered volunteers about their next shift and deliver sign-in codes for check-in, all triggered automatically from inside the platform.

Mobile Message gives platforms a REST API that sends from 1.6¢ per message, with no monthly fees or minimum spend so you only pay for what your customers actually send. Messages go out under your platform's own name or a shared number, and replies land back through the API or a shared team inbox so support requests don't pile up.
