Sending emails is a one-liner in Django. Am I a sucker for not building my own email sending service?!
Of course being a Google demo they have to include the obligatory ad server service, in Java no less. Nonsense like this is why I'm steering my kids away from considering software development as a career.
An example of an email sending service is Sendgrid, who have built an entire company around this service.
They are alive because they take the spam blame for you.
It's still a one-liner once you've configured your async task handler. Which makes the example custom email sending microservice even more ridiculous when it can be done trivially by configuring proven off-the-shelf components and third party email delivery services.
I wasn’t sure how ready rq was for prime time, but I’ve hit far too many celery bugs and the maintenance hasn’t been great for awhile.
Django-RQ's job decorator is basically a drop-in replacement for Celery's task decorator. Django-RQ's built-in Django admin app is very nice.
My Celery usage was pretty simple (mostly background email sending and PDF generation) but for those use-cases Django-RQ has been a very good replacement. Your mileage may vary of course.
