I suspect in many cases people use Celery only to send emails or for simple queueing type problems. At risk of being overly negative, my experience with celery has been that it is complex and hard to configure and debug. I chose a simple queueing mechanism instead of using Celery, and for sending emails I was so frustrated by Celery that I wrote the Arnie SMTP buffer server (in 100 lines of Python): https://github.com/bootrino/arniesmtpbufferserver https://github.com/bootrino/arniesmtpbufferserver
