It supports single-shift, recurring, and multiple-shift events, plus virtual and in-person events and actions asking people to call legislators’ offices.

Organizations can recruit event hosts, customize campaigns, reach hosts across channels, and apply approval processes and permission levels. Listed tools include shift scheduling, volunteer messaging, hours tracking, custom forms, and self-signup. Mobilize provides real-time event data, CSV export, read and write APIs, and SQL mirrors or database replicas. Integrations include NGP VAN, EveryAction, PDI, Blue State Digital, ActionKit, Salesforce, Mobile Commons, Phone2Action, ActBlue, Intercom, Moveable Ink, and Amplify.ai. The maker says its network includes more than 3,000 mission-driven organizations and over 11 million supporters.
