Turning Your Mail into a Personal Assistant

Interesting piece out of the IFTTT blog. Here with GMail.   This shows a pretty trivial example of how to look at a stream like your GMail, apply some logic intelligence to it, and alert you to related needs.    I don't think the specifics of the example would be useful to me, but the idea is well presented.  Adding more complexity to the logic, algorithms, pattern matching would be useful as well.  How might Microsoft Flow work with the same idea?   A meta conversation with your email, but not a very deep one.
