Saying it uses Machine learning is a bit sensationalized, this seems to just give you static guidelines.<p>They may arrived at the guidelines using ML, but it's possible that their guidelines wouldn't be right for the types of emails you are sending out.
as a newcomer to machine learning.. how does one build a training set of "tens of millions of emails" ? This is one of the things I have struggled with... its probably much harder to build a training set than the libraries and the algorithms themselves.<p>are there companies that build training sets for you... or something else ?
