django-subscribers is a high-volume mailing list and newsletter manager.

  • Import and manage large mailing lists.
  • Allow users to sign up from internal and external sites.
  • Allow users to control their subscriptions and unsubscribe.
  • Send thousands of HTML newsletters a day.

It's been designed to allow high volumes of newletters to be sent out in batches to avoid overloading commodity SMTP servers.
