This app has been very useful to us personally.
PaperKarma allows you to take pictures of junk mail you receive that you want to stop. You simply take a picture of the mail item that includes the name and address of the company that you want PaperKarma to notify to stop sending you mail.
The app keeps track of the requests you’ve submitted and indicates if the company has acknowledged your request, or if it is pending.
While not fool proof, our experience has been positive in reducing the amount of unwanted mailings received. Some companies take some convincing, but it’s easy to keep sending them requests using PaperKarma. Some companies are shrewd and know not to place their address and/or name together on documents which makes it hard to get a picture that provides both that PaperKarma can use.
And, of course, there are ones that seem to not care and still send the unwanted mail. But, this app has reduced the amount of unwanted mail we receive.
