Lay the communication infrastructure that holds when it matters most

Equip communities with alert programs, and consolidate community data -  so outreach is targeted and ready to activate when it counts.

Reach communities in crisis — fast, reliably, and at scale

Send real-time alerts and enable two-way communication so communities can respond, report needs, and request help instantly.

Restore stability and rebuild with communities

Keep people informed, supported, and connected through every step of recovery. Confirm safety and gather needs assessments at scale to give relief coordinators the data they need to deploy resources effectively.

"Navigating severe weather events is a near universal experience, and access to information is a lifeline when those moments strike. Our goal is to use our funding and technology to guarantee early warnings for everyone by 2030. We are building a reliable connection that helps communities prepare for weather-related disasters. This ensures our neighbors have the clarity they need to take immediate action and stay out of harm's way."

Twilio.org’s grantmaking is part of what fuels the Disaster-Ready Communities program by investing in nonprofit organizations that are transforming how communities prepare for, respond to, and recover from weather-related crises. Through a combination of catalytic funding, technology, and deep collaboration, we support digital solutions that expand access to trusted, real-time communication. In doing so, this ensures that critical information reaches people when it matters most.

Our strategic investments help strengthen local capacity, enable multi-channel early warning systems, and accelerate the adoption of scalable, community-centered approaches to resilience.

Twilio for Disaster-Ready Communities

Getting started is faster than you might expect. With Twilio's APIs, developers can send their first voice alerts in minutes.  For organizations without dedicated engineering resources, Twilio's pre-built templates, partner integrations, and Professional Services team can help you launch a production-ready notification system in days — not months.

Twilio supports SMS, Voice, RCS, WhatsApp, and Email  — so you can reach community members on the channels they already use and trust, including those without smartphones or data access. Messages can be sent simultaneously across all channels, and delivery can be prioritized and cascaded based on read or response rates, helping ensure no one is left unreached.

Twilio's infrastructure is built for high-volume, time-sensitive delivery — with 99.99% uptime SLAs and global carrier relationships across 180+ countries. Whether you're sending 1,000 alerts or 1 million, Twilio's platform scales automatically via a resilient, self-healing multi-tenant architecture.

 Unlike one-way broadcast tools, Twilio enables real-time, two-way messaging so recipients can reply with their location, confirm evacuation status, or request assistance. Responses can be routed to dashboards, ticketing systems, or contact center agents in Twilio Flex — giving response teams a live, actionable picture of conditions on the ground throughout the event lifecycle.

Twilio offers a Lookup tool that validates phone numbers before sending messages. Twilio Verify adds an additional layer of security by authenticating recipients via one-time passcodes — ensuring that emergency funds, supply distributions, and critical notifications reach verified, affected individuals and reducing the risk of fraudulent claims during high-pressure recovery operations.

Yes. Twilio's messaging and voice APIs support message delivery in any language, and Twilio IVR can be configured with multilingual call flows to serve affected populations in their preferred language. Organizations like the Norwegian Refugee Council and UNHCR use Twilio to communicate with displaced and vulnerable communities across dozens of languages globally
