That is true. I wish I could have a setup like that. Given the number of email services I have created a dependency on all these years, I don't see an easy way to combining all into one at least without losing contact with services and people who may still be only aware of my abandoned accounts. Even with my current setup where everything is accessible from a single login, the final result is that all spam, notifications and important emails end up in the same inbox, which I have no solution for yet. It is still a struggle to keep the inbox conversations list as low as possible so that I do not miss anything important. Having said that, it is still way better than what it was before :)
