Answer 1

One approach would be to use signals: "The Django Signals is a strategy to allow decoupled applications to get notified when certain events occur." So you set up a function that, based on a event, will generate an email. You have plenty of examples on the web. For instance:

So how do you create the event? Someone asked on stackoverflow this question and you will find a nice approach:

Set up a scheduled job?

In a nutshell, you create a custom management command and use cron (on Linux) or at (on Windows) to run your command at the required times. Thus you avoid celery.
