I enjoy using HEY from 37signals. It's different than other services (more opinionated), but it keeps my inbox under control. They also take privacy seriously.
I was a paid subscriber for the first year, stopped for a year, and then went back because I realized how much it helped. It lacks a calendar, though, if that's important to you.
