And yet I still use email because I am no longer inundated with spam thanks to the likes of Google and Microsoft. Without them I'd have given up on email altogether.
I run a mailserver with bogofilter, which, with a few months of training, is surprisingly effective. Before that, dspam was also very effective. Spamhaus makes a decent effort on providing blacklists. I don't see what google and M$ is bringing to the table, apart from pain for indie (still validly configured with DMARC, DKIM, SPF) mailservers.
