Love it

I’ve used this app to unsubscribe from hundreds of mailers and for 95% of them, I never heard from them again!

Reduced junk mail!

When I moved into my condo as a first-time home owner, I was getting dozens of advertising mail every week for the past previous owners and there were many. I would see several different household names that the mail was addressed to. I’ve been using this app for 4 years since I moved in and have seen a big difference in the reduced mail I get now. It took a few weeks/months to see the majority of the mail reduce. Now I only get mail addressed to me (with an occasional random mail to someone else) but I can even eliminate the ones I don’t want to get. As I keep getting mail from random companies, I keep using this app. The companies I request to stop sending mail, do actually stop. This has been such a useful service and is really worth it. So grateful it exists.

Works but app is glitchy

App works but the logo identifier is useless; location services doesn’t work as it seems the developer hasn’t kept up with iOS updates. It’s a manual process but it still does what it says. Hope they clean up the bugs.

No Longer Working

I was somewhat skeptical of this app, but after paying for an upgrade and using it for several months, my junk mail has gone down. The logo identification feature almost never works and comes up with some really bizarre potential matches.

After upgrading iPadOS, the app no longer works. Whenever I try to take a picture of logo, I get a message stating the flash is disabled and I cannot add the mailer.

Developer has not responded to my contacts through the app.

Give it a couple months and you’ll start to notice the difference.

We’ve been using PaperKarma for several months now, and the difference really stood out when we went out of town. When we returned, we had only about a sixth of the mail we’d received during the same trip the previous year.

Last year, after placing a mail hold with the post office, we came home to nearly five pounds of mail—almost all of it junk, aside from a few holiday cards from family and friends. This year, after using PaperKarma and being gone for the same amount of time, we had only a couple of advertising pieces. Everything else was legitimate mail from friends, family, or businesses we actually needed to hear from.

Be patient—you’ll see that it works. Keep taking photos of the mailers you don’t want, and over time the junk pile really does shrink.

Works behind-the-scenes, but the app is terrible

My main complaint is you have to use their photo recognition to find the company. It only worked for me a few times. I always end up searching manually, but I have to take a photo and wait for it to process.

The entry process for your name and address is very tedious. I don’t know why you have to fully enter a new address for each person. Can I not just use a previous entry as a starting point?

It just feels like they have never used the app or they would have noticed these

It seems to work on the backend though, and my junk mail has gone down significantly! So 3 stars

Scam

I paid for an upgrade so I could add addresses. However I’m still unable to do that. And customer service has not respond to my email.

Ineffective

The app requires you to take a photo of the envelope to determine the sender. But it is almost never accurate. So I just take a photo of my table, which it categorizes as “Scott’s Lawn Service” or similar nonsense, and override it with the correct answer.

More to the point, it doesn’t work anymore, if it ever did. At first I saw maybe a 30% reduction in spam. Better than nothing, so I kept at it. Now it is practically useless. I have submissions from 4+ years ago that it confidently claims are “unsubscribed” and there they are in the mailbox again the following week.

Getting worse.

I understand that removal of your name from various mailing lists is a tedious process. However, when I subscribed to this application years ago, the success rate was substantially higher. Right now, not only can the application never find the mailer when I take the picture with the app, even if the mailer is well known. For example, American Automobile Association.

But almost always, the submissions via the app result in absolutely zero impact. I continue to receive junk from the same companies three months later, six months later, one year, two years. Even repeat submissions for the same company do not result in any improvement.

If my success rate of having the junk mail stopped via PaperKarma is 20%, then even that is probably an overestimation. Not recommended.

Please remove photo aspect

Please remove photo of logo aspect as it never works - 100% failure rate - and only wastes users time.

App is currently broken

September 25, 2025- App is completely broken, nothing is working.

Full of bugs

App crashes half of the times I try to use it

Not worth the price

I decided to pay for this app because I get a lot of junk mail. Do not pay for it. I was supposedly unsubscribed from certain mailers (according to the app) but I’m STILL receiving mail from those companies. Also, support is almost non existent. I wish I could get my money back, because even though it wasn’t much, it’s still not worth spending if this company isn’t going to do their job.

Pointless service- does nothing

Still getting junk mail after 12 weeks, this app and service are completely worthless.

Best app to save time and the environment

I was so sick of getting junk mail when I read about Paper Karma in a substack article. It’s the best $25 I ever spent. Not only do I not have to spend hours sorting through junk mail for recycling, garbage and shredding, but our mail has been reduced to a maximum of one or two pieces a day, when previously it was 7 to 10 pieces a day. Junk mail pollutes our environment. It also wastes our time. Get Paper Karma today and save yourself the hassle. Just a few minutes a day and within a few weeks you will notice a huge difference in the amount of junk that comes into your house.

Love it

I was just scrolling through two years worth of unsubscribed mailers and enjoyed seeing the names of many many mailers that I have stopped receiving mail from.

Doesn't work

Won't let me register, it just gives me a vague error message that doesn't offer any helpful information

My favorite app of all time

Paper Karma has completely stopped all our junk mail. I tried repeatably to stop Amex card offers but they kept on coming until Paper Karma. It did take a little time to get off the lists but it works. We hardly get any mail these days. Highly recommended.

Cancel subscription?!

Well 1st IF I got an email notice of pending subscription renewal, I didnt recognize JetLLC, so it renewed-also it seems after countless requests to stop so many charities requesting$ theybstill come-been a year

Not As Advertised

While the app has good intentions, it does not deliver. Does not recognize the addresses I submit by photo. Will be deleting this.
