Case Study: 350.org Builds a Youth Climate Activist Network and Drives Strike Attendance with CallHub

How 350 used text messages to organize the Climate Strike

350.org, through its Minnesota affiliate MN350, needed a better way to turn a large base of online climate supporters into active participants for rallies, volunteer recruitment, and other offline actions. The challenge was engaging young activists in a personal, timely way and building a contact list that could be used for targeted outreach. They used CallHub’s texting tools, including SMS opt-in and peer-to-peer texting.

With CallHub, MN350 collected opt-ins at events, gathered supporter data through automated follow-up questions, segmented lists by age, school, and location, and then sent targeted peer-to-peer and mass texts. The results were strong: 2,919 attendees opted in by SMS, peer-to-peer outreach generated a positive response rate of over 22% for volunteer recruitment, over 10% said they would come to the December 6 strike, and a later petition drive also saw a 22% positive response rate.
