My Email Management System uses the following services and a few more. This is how I have these services work together.

Identify a group of emails that are not spam but you don't want in your inbox. Use gmail's filter to forward the email to email@example.com. I typically archive the email and give it some label so that it remains searchable in gmail, but you can simply delete it if you wish.
All email that get sent to firstname.lastname@example.org are now part of a (public) feed at mailbucket.org/something.xml. I now import this feed into google's feed reader. Most of these feeds go to my info label in the reader.
Please note the MailBucket Feeds are updated every hour and will not appear in the feed right away. A list of the last ten emails are available at mailbucket.org/simple/something

It arrives at my gmail account
It gets forwarded to a mailbucket account

The feed is picked up my google reader
The reader files the item under info
The info label is read by my google/ig widget
