Sending letters, how to implement on Django?

Question

Django

There is a goal, to send every day a letter to a certain address. (for example)
How to implement it? I read about sending emails, everything is clear here, I can send an email on a specific event. But in my version, there is no event, the next day just comes, the function works out and the letter leaves, all this is in the background without calling the function.
