The project involves creating a minimal email newsletter backend using Python's Django Web Framework and Twilio SendGrid's core email-sending API. The application allows users to create, confirm, and delete subscribers, as well as upload and send newsletters. The system uses Django's built-in admin interface to manage the data and SendGrid's email API for fast and reliable delivery. The project covers key aspects of building a web application with Django and integrating it with an external service like Twilio SendGrid.
