Convert email newsletters into Atom feeds
Kill the Newsletter doesn't actually kill newsletters heading for your inbox, but it converts them into RSS feeds that you can then plug into your RSS reader of choice. In fact, your email address doesn't have to be involved in the process at all—you use your RSS reader to stay on top of your subscriptions rather than your inbox, which takes us back to the good old days of Google Reader.
There are no complicated settings or screens to get through in this particular tool: It's free to use, and you don't even need to sign up for an account
Just enter the name of the newsletter you're subscribing to and you get a custom email address to use when signing up, and an RSS feed that will relay newsletters sent to that address.
