Regarding the usage of celery, maybe this would be a nice small addition to the docs:

In your apps task.py file, add the following:

from celery import shared_task

from mailer.management.commands.send_mail import send_all

@shared_task
def sendMails():
    send_all()

This seems to work without any issues, although I am not a 100% sure if it's a clean way of doing this.

Regarding the three config parameters for rate limiting, after closer inspection, I think I have an idea on how to achieve "dynamic" rate limiting based on time of day. Consider the following:

@shared_task
def sendMails():
  hour = timezone.now().hour  
  if hour >= 8 and hour <= 18:
    setattr(settings, "MAILER_EMAIL_MAX_BATCH", 20)
  else:
    setattr(settings, "MAILER_EMAIL_MAX_BATCH", 10)

  send_all()

However, this seems at least a bit hacky to me.
