I don't think that is an EEE attempt on email. What is (I think) an indirect EEE (I mean we'd be mad at them if they didn't do it) is requiring strict adherence to DNSSEC/SPF/DKIM/DMARC. With the requirements changing very often it's hard as a regular guy running an email server to keep your mail from ending up in spam folders on the big providers.
What I want to know though, is why does my mail from a domain with properly configured SPF/DKIM/DNSSEC and DMARC end up in spam, and so much spam not? :P
