I’ve been using Paperkarma for a few months now and I’m glad to say it does work to reduce your junk mail for your home!
It’s an iPhone or android app that you can take photos of your physical mail and it will send a request to take you off of their mailing list.
The best part is that you can review your past request and know that you haven’t seen these mail recently so you know it’s working. It’s one less thing to sort through when I get home now. We now have about 1-3 letters in our mail box instead of the over flowing one which we grudgingly sort through.
Here’s a Youtube video from Digitwirl which explains more about the app.
