Thanks for sharing a small writeup of a neat thing you did! I think maybe the parent comment missed the context, which is that you wanted to add an email signup to an otherwise static site. In that context, setting up a VPS would now mean that you have to be responsible for a new pet, including security updates and monitoring. You would also have to change your deployment tooling / workflow to something quite different (pushing and restarting a running service, rather than just running aws s3 sync ...) Of course I don't think I would take this approach if I already had a backend service hosting a site, but I certainly would experiment with it if I were in your situation.
