This tutorial demonstrates how to send recurring emails in Python using the Twilio SendGrid API, Redis Queue, and RQ Scheduler. The process involves setting up a development environment with Python 3, installing necessary dependencies like SendGrid Python library and RQ Scheduler, configuring an API key from SendGrid, and writing code to send emails and schedule tasks. The tutorial also provides instructions on how to run the Redis server, RQ worker, and RQ Scheduler process in separate terminal windows for successful execution of the scheduled email task.
