Organizations can create single-shift, recurring, and multiple-shift events, as well as virtual and in-person events and actions asking supporters to call legislators’ offices. Volunteer engagement features include automated email and text messages, post-event surveys, personalized experiences, and event search and discovery. Organizations can also recruit event hosts, customize campaigns, reach potential hosts across channels, and set approval processes and permission levels. The service includes shift scheduling, volunteer messaging, hours tracking, custom forms, and self-signup. For reporting and integrations, it offers real-time event data, CSV export, read and write APIs, SQL mirrors or database replicas, and connections to tools including Salesforce, NGP VAN, EveryAction, and ActBlue. Mobilize says its network includes more than 3,000 mission-driven organizations and over 11 million supporters. Its free plan costs nothing for five team members and the next five events or online actions, with up to 50 signups or 500 petition signatures.
