Professional Networks newsletter system launches
The Guardian Professional Networks registration — 2nd October 2013
A new bulk mailing system has been added, allowing email newsletters to be created, scheduled, and dispatched to high-volume mailing lists. The system is designed to handle millions of emails per month, at a rate of 100K emails per hour.
The system makes heavy use of RabbitMQ and Celery to parallelize sends amongst a large number of background workers, and is horizontally scalable should future volumes increase.
Other key technologies contributing to the send performance include PostgreSQL full text indexing and Amazon Elasticache.
