I used Zappa[0] and AWS Lambda to host a Flask application recently. After years of deploying Flask applications to VPSs behind Apache, I was pretty impressed by how simple it was to deploy a serverless app. Nice that there's no need to worry about security patches, OS updates, HTTPS cert renewals, etc. And so far it's waay cheaper for my usage too. If your Django app doesn't have too many dependencies, it might be worth considering. Then you can use AWS Simple Email Service (or any of the many third-party services already recommended) for the email needs.
