Sounds like something that should be an open-source self-hostable mail bot :). Does anyone know any such project?
I encourage people to reinvent the wheel but only if they can do better or think they can atleast.
No point if your aim is to build the exact same thing at same price point and is a copy.
Well if you market it better, it will not be a copy in my book.
I concur with the idea, it is a good open source project.
