AI Powered Email Assistant

I'm looking to build an Autonomous AI Assistant that can constantly help me manage my email inbox. I'd like to be able to train it overtime using natural language. I want it to be able to recognize advertisement or solicitation emails, emails from clients of mine requesting IT support. I want to it identify receipts and invoices and forward them on to another email. I would also like for it to create daily digest summaries for all the emails I receive in a day.
