[feature] Email module

Thanks for this write up! I don’t know if this was prompted in part by my comment, but this is exactly the info I was looming for.

I’m pretty ignorant about the different mail handlers and why you would use one over the other. I like the idea of having a common class that could call any of the different implementations, useable with minimal to advanced configuration. My current projects use SMTP or an already-configured server email.
