What is an alternative way to send a django newsletter?

Question

Django

In the django-newsletter module, the following command is used to send all scheduled mailings: It is
manage.py runjob submit
recommended to use cron jobs for sending, but I would like to provide the ability to send letters in the mailing list through the web interface.
I did everything trite:

sub = Submission.objects.get(id = int(sub_id))
    if not sub.sent:
        try:
            sub.submit()
            sub.prepared = True
            sub.save()
        except:
            pass

The standard admin interface has a submit button, but after that the module will wait for a command in manage.py
Actually, the question itself is: is it possible to somehow change the standard admin interface of this module without resorting to changing the library itself?

Answer 1

The problem is that in the admin panel you have to wait a long time until the letters are sent, did I understand correctly? If yes, then I recommend only running a command in the admin panel that will perform mailing in the background. For example, this can be done using Celery.
