There's a much easier solution: the vast majority of legit auto-generated email will have a "List-Unsubscribe" MIME header. I filter based on that header into a 'Bulk' folder.

There are some exceptions, e.g. emails that go via the Drip service, but given limited number of automated email services you can probably catch 99% of emails with a few rules, rather than machine learning.

Interesting. I've collected quite a few from friends + colleagues already and only one has such a header.

Also, that doesn't help with my having fun and learning more machine learning!
