📧 Kill the Newsletter!

Leandro Facchinetti created a nice little service:

How does Kill the Newsletter! work?
Create a feed with the form above and Kill the Newsletter! provides you with an email address and an Atom feed. Emails that are received at that address are turned into entries in that feed. Sign up to a newsletter with that address and use your feed reader to subscribe to that feed.

Feedbin, my feed service of choice, has a similar feature that I use extensively.
