I utilize Redis for task management and workers to process these tasks efficiently, ensuring that no emails are lost even if the worker crashes. I demonstrate how users can log in using Google OAuth and send or schedule emails, including a test where I scheduled a mass email to 100 recipients. I also explain the rate limiting feature to prevent abuse and how the system maintains job integrity through worker-side idempotency. If you're interested in trying it out, all the setup details are in the README file.
