send_mass_mail in background django

I am using send_mass_email to send emails to a list of users. It is working fine until I send it to more than 200 emails at a time. Actually emails are being delivered without a problem. But I am getting time-out error from nginx because it takes long( more than 2 mins) to send emails to all 200+ emails.

What is the best way to run send_mass_mail in background ?

You can make it a management command and then setup a periodic cron job to send out the emails refer management command docs

You might want to look into the django-mailer project, which encapsulates this functionality - it does this via crons, rather than using a task queue. I've been using it for a while with good results.

You need to move the tasks to the background (so they don't block the web process). One of the most popular ways to do this is to use a messaging/task queue.

Celery is one of the most popular distributed task queues, and coupled with the django-celery application makes this trivial.

First you need to setup celery (which is as simple as pip install -U celery); and one of the many messaging brokers that it supports. The most popular one is RabbitMQ; but for quick and dirty set ups you can also use your existing database as a message broker.

Finally, since this is a common problem solved by celery+django, there is django-celery-email which takes care of the rest.

You can send mails in separate thread, for example:

t = threading.Thread(target=send_mass_email,
            args=[messages],
            kwargs={'fail_silently': True})
t.setDaemon(True)
t.start()

or just use cron and django management commands =) https://docs.djangoproject.com/en/dev/howto/custom-management-commands/
