"Finally an "unsubscribe app" that let's you *actually* unsubscribe and filter using Gmail filters (instead of always relying on the 3rd party app to filter those emails). Big plus for me, so I have all filters in one place (inside the Gmail filters, that is). Awesome work! Already a fan :)"

"I was mostly hoping to turn my email inbox into less of the mess that it is. I've been losing tasks that I should do as the emails get buried. So far it's really helped."
