Stop unwanted catalogs, credit card offers and other paper junk mail. Snap a photo with PaperKarma and we'll handle the opt-out request for you. Spend less time sorting, shredding and recycling mail you never asked for. PaperKarma helps you contact the senders and get off their mailing lists, without researching each company's opt-out process yourself. HOW IT WORKS 1. Take a photo of the mailer's name, logo or return address. 2. Confirm the sender and select the name and address shown on your mail. 3. Tap Unsubscribe. We send the opt-out request on your behalf. CHOOSE WHAT YOU WANT TO STOP Request removal from mailing lists for catalogs, credit card and insurance offers, charity solicitations, and other unwanted mail from national and local businesses. Your bills, statements and important account mail are not affected. You choose which senders to unsubscribe from. MAIL FOR SOMEONE WHO MOVED OUT? Save multiple names and addresses, including name variations and previous residents receiving junk mail at your home. Select the exact name and address printed on each piece for the best match. PRIVACY MATTERS We do not sell, rent or trade your mail photos, name or address. We share the information needed to carry out the opt-out you request. If a mailer requires your email address or phone number to verify an opt-out, we ask for your specific consent first. See our Privacy Policy for details. WHAT TO EXPECT Stopping mail takes time. Allow 8-12 weeks after your request is processed for mail already scheduled or printed to work through the system. Timing and results depend on the sender. PaperKarma works with addressed postal junk mail in the 50 United States. It cannot stop Every Door Direct Mail (EDDM), unaddressed flyers, or election and ballot-issue postcards. Mail addressed only to a generic recipient such as "Current Resident" is generally not supported. SUPPORTED MAILERS PaperKarma helps you request removal from mailing lists for 100,000+ national and local mailers, charities and organizations. Examples include Capital One, American Express, Discover, Allstate, GEICO, State Farm, Restoration Hardware (RH), Wayfair, Valpak, Money Mailer, Save.com, AT&T and Xfinity. From credit card offers and insurance promotions to shopping catalogs and coupon mailers, choose the senders you want to stop hearing from.

Verdict
The clearest difference is review sentiment: Cribbo at 100% against PaperKarma's 33%. Cribbo also leads on rating (5.0 vs 4.4). PaperKarma's advantage is ratings volume (1.1K vs 2) and monetization model (free with in-app purchases vs paid). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PaperKarma sells 4 in-app purchases, starting at $3.99 per month and Cribbo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Cribbo holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: PaperKarma has 1.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of PaperKarma's written reviews are positive against 100% of Cribbo's.
PaperKarma ships an update monthly, Cribbo every 6 weeks. Both last shipped on October 29, 2026.
