Laravel is a popular PHP MVC framework that supports multiple SMTP providers by default, but SendGrid is not available out-of-the-box. This tutorial aims to help developers implement SendGrid as an SMTP relay in Laravel for sending emails to registered users, including email verification and tracking features. To set up the project, create a new Laravel application, install dependencies, add database connection details, create a SendGrid account, generate API keys, configure the mail driver, and enable authentication scaffolding with email verification. The tutorial also covers testing the application, verifying emails, and checking the activity on the SendGrid dashboard to understand how the process works.
