Fastmail is excellent. They have subdomain addressing, which is kind of like plus addressing, but better (not all places let you sign up with plus addressing).
I've got my own domain, for example: mydomain.com. So my fastmail email address is depingus@mydomain.com. But with subdomain addressing, I can sign up for services with unique email addresses that look like:
social.hackernews@depingus.mydomain.com
Fastmail will automatically route incoming messages arriving to this email address to my "social" folder. If I start getting junk to that address I can easily blacklist it.
It wasn't easy switching out my email address EVERYWHERE. And there are places that won't even let me change it. But in the end, it was so worth it. I don't even miss Google Inbox anymore!
