This is a notification service. They sent 2.6M emails, 2.8M text messages, and 60K letters yesterday [0]. That’s about 30 emails per second, 32 SMS per second, and less than one letter per second. That’s not nothing, but it doesn’t need crazy processing efficiency either. Most of the work will be I/O bound, just messages sitting in a queue waiting for the receiving service to be able to accept them. Python is fine for this. You don’t need email to be sent ASAP; in fact a lot of work goes into making sure you don’t send high volume too quickly in case you look like spam.
