For moving away from Gmail, I'd be interested in solutions that help you data-mine ahead of time how many mailing lists/services/etc you have linked to your address.

It might be easy to just "switch" one day away from Gmail, but it could easily be weeks and months of manually unsubscribing/notifying/etc providers of the new address to use.
