I now pay some company to deliver my personal mail, which is just dumb, and clearly isn't caused by them being better about spam (as I sent no spam): it is caused by a militarized anti-spam-crazed group of people who have managed to build a system that essentially requires an oligopoly for email to function. A lot of these people don't even consider it a problem to use "report as spam" as a ways to punish companies for things that aren't even sending spam (which is something I only bring up as it demonstrates the "militant" comment).
The reality is that an open internet where people can talk to each other without going through third parties requires a world in which you, heaven forbid, receive some spam. It is actually a similar construction as the one for why we should have network neutrality: large internet carriers in the world of email should, if you really believe in open access, not be allowed to say "these people can't send mail because they are too small and not paying someone". We all need to accept at least a little spam to guarantee everyone can send mail.
If this means that you have to get better at dealing with spam, as some of the heavy-handed techniques people have put in place for dealing with spam are no longer possible, well: so be it; and if that means you need to turn off the notifications for new email on your phone to keep from getting angry when you receive some spam (which tends to come up as a reason to hate spam), I hope people realize that they caused their own reason to be upset, and that getting notifications for anything is probably unhealthy, at least for you, anyway.
Sadly, the large companies who have slowly come to "own email" have no incentive to break this cycle, whether in action or in words, as the current state of affairs is what is giving them their power: whether they build solutions that can solve spam in a way that is both fair and federated, or they just try to educate users about how to better deal with spam and decrease the stress in their lives (including telling people to stop letting email interrupt them), it will just harm them. This doesn't sound like something the private sector can solve.
