Channel-by-channel playbook.
Go down the list and run every step that applies to you. Each link goes straight to the form, app, or setting.
Robocalls
- Register on the National Do Not Call list. Free, 30 seconds. Stops legitimate telemarketers (scammers ignore it, but it cuts the legal noise immediately). donotcall.gov
- Turn on your carrier's free spam blocker. All four U.S. majors include one. T-Mobile Scam Shield · Verizon Call Filter · AT&T ActiveArmor
- Silence unknown callers in the OS. iPhone: Settings → Apps → Phone → Silence Unknown Callers. Android: Phone app → Settings → Caller ID & spam → Filter spam calls.
- Install a third-party blocker (optional, powerful). YouMail, Hiya, or Robokiller.
- Report repeat offenders to the FCC. Each report builds an enforcement case. FCC complaint form
Spam texts
- Forward the message to 7726 (SPAM). Free on every U.S. carrier. Your carrier uses it to block the sender for everyone on its network. Don't reply, don't click, don't text "STOP" to unknown senders — that just confirms your number is live.
- Block + Report Junk. iPhone: tap the sender's name → Info → Block this Caller, and use Report Junk. Android Messages: long-press → Block & report spam.
- File one FTC complaint. Takes a minute, helps fund enforcement. reportfraud.ftc.gov
- Stop publishing your number. Most spam texts come from data brokers selling your number. Use the broker list below — it's the only fix that compounds.
Email spam & junk newsletters
- Use the unsubscribe link — it's the law. CAN-SPAM requires every U.S. commercial sender to honor unsubscribes within 10 business days. If they ignore it, that's a violation, not an annoyance.
- Mass-unsubscribe in one sweep. Gmail: in the search bar type
unsubscribe— every list email is one click from gone. Or use Leave Me Alone (paid, no data resale) instead of Unroll.me (which sold inbox data). - Filter before it hits you. Gmail: Settings → Filters & Blocked Addresses. Outlook: Rules → New Rule.
- Stop giving out your real address. Use an alias service for every signup — see Section B below.
- Report the worst senders. Gmail: ⋮ → Report spam and Report phishing. Outlook: Junk → Phishing. Senders that get flagged get reputation-throttled by the receiver.
Direct mail & junk catalogs
- Stop prescreened credit & insurance offers — free, 5 years. The big one. Run by the credit bureaus themselves. optoutprescreen.com
- DMAchoice — opt out of marketing mail for 10 years ($6). Run by the Association of National Advertisers; covers most of the legitimate direct-mail industry. dmachoice.org
- Catalog Choice — kill catalogs by name (free). Pick the catalogs you don't want and they email the sender to cease. catalogchoice.org
- Add yourself to USPS Informed Delivery. Daily preview email of your mail. You'll see junk before it arrives and can recycle without opening. informeddelivery.usps.com
The actual source: data brokers
Almost every spam text, robocall, and direct-mail piece traces back to a data broker — companies whose business is buying, packaging, and reselling your name, number, address, and inferred interests. You have a legal right to opt out of every one, but you have to do it broker by broker.
- The do-it-yourself path. Use the broker hit list in Section C below. Each opt-out takes 2–10 minutes. Doing the top 30 silences most of the channel — the rest is long tail.
- The pay-someone-else path. If 30 forms sounds like work, services like DeleteMe, Optery, or Kanary handle ongoing removal for ~$100–200/year. They re-submit when brokers re-list you (which they will).
- Lock the front door too. Freeze your credit at the three bureaus (free, online) so brokers can't pull new files on you. Equifax · Experian · TransUnion
