Show HN: Self-Hosted Email Service via Cloud Run

This is a quickly deployable self-hosted solution for sending emails using your own GMail account. I found it perfect for quick prototyping. It's hosted in your Google Cloud Project, requiring minimal configuration. The main goal is to streamline the process of sending out emails via POST requests, without the hassle of setting up new accounts outside of your project, etc.

I'd appreciate any feedback or suggestions you might have. This is the first time I'm sharing something here so hope this is the right thread. Happy coding!
