You’ve probably seen it: a text you never asked for, ending with “Reply STOP to opt out.” It seems like the responsible thing to do is reply and make it go away but depending on who sent it, replying STOP can either solve the problem or make it worse. Here’s how to tell the difference, and how to deal with the other flood of unwanted marketing that shows up every day.
When Replying STOP Is Safe
If the text comes from a business you actually have a relationship with, replying STOP is the right move. Think of your pharmacy, a retailer whose deals you signed up for, your airline, or your bank’s alerts.
Legitimate companies in the US have to honor opt-out requests under the Telephone Consumer Protection Act (TCPA) and wireless carrier guidelines. These messages usually come from a short code, a 5- or 6-digit number rather than a regular phone number. When you reply STOP to one of these, you’ll typically get a single confirmation text and then nothing more.
When You Should Never Reply
If the text is from a sender you don’t recognize, especially one using a regular 10-digit phone number or an email address, don’t reply at all.
Scammers copy the “STOP to opt out” line because it makes their messages look official. When you reply, you’re confirming that your number is active and that a real person reads their texts. That makes your number more valuable, and it can end up on more lists and bring you more spam.
Instead, do this:
- Report it. Forward the text to 7726 (which spells “SPAM”). This works on all major US carriers. You can also use your phone’s built-in reporting: “Report Junk” on iPhone or “Report spam” in Google Messages.
- Block the number and delete the message.
- Don’t tap links or call numbers in the text, even if they claim to unsubscribe you.
If you’re not sure whether a text is real, look up the company’s official website or app and contact them directly.
The Other Spam Problem: Your Mailbox
Spam texts get most of the attention, but paper junk mail is just as persistent and, in some ways, harder to stop. Credit card offers, catalogs, coupon packs, and “current resident” flyers can pile up week after week. Unlike a text, there’s no STOP button to press.
Junk mail isn’t just clutter. Pre-approved credit offers contain personal information that identity thieves can steal from your mailbox or recycling bin. And the sheer volume means paper waste and time spent sorting. That’s exactly the problem Opt Outs was built to solve. Instead of hunting down every company’s opt-out process, you use the app to handle unwanted paper mail right from your phone, and Opt Outs takes care of getting you off the list.
It works for the catalogs, credit card offers, and mailers that the big opt-out registries miss, so you can clear out your mailbox without spending an afternoon on hold or filling out forms. Removing your personal information from email lists in tern can reduce your spam texts if they’ve been coming from those companies as well. Opt Outs is available for iPhone and Android at optouts.app/download.
The Bottom Line
For texts, the rule is simple: reply STOP to companies you know, and report and block everyone else. For junk mail, start with the official opt-out sites, then deal with individual senders, either one by one or with an app like Opt Outs that does the legwork for you.
A little effort now means fewer scams on your phone, fewer stacks of paper on your counter, and less of your personal information floating around.
