Sending mass email in Django

Hi people,

I am currently maintaining a website where at times I may need to send around 10,000+ emails at a time.

I just want to ask on what methods you may consider Django best practices e.g. in efficiency when sending mail to a list of this size?

I am currently handling this as a celery task and sending the emails through Mandrill transactional email service

Currently, this is how I am handling it:

from django.core.mail import EmailMultiAlternatives, get_connection
from models import Subscriber

connection = get_connection()
recipients = [i.email for i in Subscriber.objects.all()]

for sub in subscribers:
    msg = EmailMultiAlternatives(title, content, sender, [sub])
    msg.attach_alternative(content, "text/html")
    recipient_list.append(msg)

connection.send_messages(recipients)

Is it better to split the list into smaller chinks to reduce the size of the requests or which other implementation methods can I consider?

Thanks
