Newsletters can be set to send immediately or schedule a later date/time to send. By default, scheduling is not enabled due to additional setup needed. To enable newsletters scheduling, follow these steps:
Add the setting NEWSLETTER_SCHEDULE_ENABLED = True to your conf/settings.py.
Make sure a process is started for the management command qcluster. On Ubuntu, you can create a qcluster service like this:
[Unit] Description=Django-Q qcluster After=network.target [Service] WorkingDirectory=/var/www/mysite ExecStart=/srv/mysite/bin/python \ /var/www/mysite/manage.py \ qcluster [Install] WantedBy=multi-user.target
Once the newsletters scheduling is enabled, you can make a schedule in the step 5 when adding a newsletter. Just check the “Schedule to Send?” checkbox, you can then specify when to send and how often to send (if needed).
