This tutorial teaches how to build an app that sends inspirational quotes daily via SMS, phone calls, and email using Twilio Programmable Voice, Programmable SMS, and SendGrid. The application uses Laravel Sail as a development environment to save time setting up the dependencies. It also demonstrates how to install Twilio's PHP helper library, set credentials, create a SendGrid API key, and implement messenger interfaces for SMS, call, and email channels. The code is written in PHP and utilizes Laravel's features such as Docker Engine or Docker Desktop, PHP 8.1 (or 8.2 when released), Composer globally installed, curl, and Laravel Sail to create the application.
