I'd like a way to filter or select which email address I'm using. I thought I'd be able to use a primary email and then a secondary to use for things such as website signups/promotional use. I want all that subscription stuff to go to a seperate place and only look at it when I want, not every time I'm in my primary inbox. I thought that would kind of be the point of multiple email addresses but everything is just an alias for the primary...I don't quite get the point or usefulness.
