With this application you can send text-to-speech notifications to up to 500 recipients using Twilio Programmable Voice. In addition, the application will track the status of each individual call that was triggered to generate you a detailed report of your broadcast. It can work as a starting point, whether you are building a voice notification solution for Emergency Alerts or Sales & Marketing use cases.

The application itself is built using React.js for the front-end and NestJS back-end and leverages a Postgres database. For a more detailed overview, check out the Technical Overview document of the project.

In addition to manually deploying it, you can also use the Click to Heroku functionality to quickly deploy it. Before deploying it, make sure you read the development considerations for the app.
