Spam is unwanted contact—emails, calls, texts, or messages—sent in bulk and usually trying to sell something, trick you into clicking a link, or steal your information. If you're getting more of it than you'd like, you're not alone. The good news: there are real, practical steps you can take to reduce it and prevent the worst kinds from reaching you.
Spam happens because your contact information has value. Your email address or phone number can be sold between marketing lists, harvested from websites, or obtained through a data breach. Once it's in circulation, it's hard to remove completely. That's why the most effective anti-spam strategy has two parts: reduce how many places have your information, and filter or block what gets through anyway.
The type of spam you receive depends partly on how your information was obtained. Marketing spam (promotional emails from companies) behaves differently than phishing attempts (messages designed to trick you into revealing passwords or financial details) or robocalls using spoofed numbers.
Most email providers offer built-in spam filters that automatically move suspicious messages to a spam folder. Gmail, Outlook, Yahoo, and others improve these filters over time, learning from what users mark as spam. They're not perfect, but they catch a meaningful portion before it reaches your inbox.
You can improve email spam protection by:
Phone spam is trickier because calls and texts feel more personal than emails, and the technology behind caller ID spoofing (making a call appear to come from a local number or trusted organization) is hard for carriers to stop entirely.
For unsolicited calls and texts:
Social platforms and messaging apps—Facebook, Instagram, WhatsApp, X (formerly Twitter)—are spam targets because they're where people gather.
Reduce spam on these platforms by:
Not all spam is just annoying—some is dangerous. Phishing emails, smishing (SMS phishing), and vishing (voice phishing) are designed to steal your identity, passwords, or money.
Key differences in malicious spam:
| Type | Method | Goal |
|---|---|---|
| Phishing | Email that mimics a trusted company | Steal login credentials or payment info |
| Smishing | Text message with suspicious link | Same as phishing; often includes urgency ("Confirm your account now") |
| Vishing | Phone call claiming to be from your bank, tech support, or government | Trick you into sharing passwords, Social Security numbers, or payment details |
To protect yourself:
Even with all these steps, some spam will get through. Spam volume varies by how long your email or phone has been active, whether your information was in a data breach, and how carefully you've protected it over time. Someone who's been online for decades may receive more spam than a newer user, simply due to exposure.
You also can't completely "opt out" of spam using a single tool or service. The spam ecosystem is distributed across thousands of lists and bad actors, many operating outside your country's laws. What you can do is reduce it significantly and protect yourself from the most dangerous kinds.
The variables that matter for your individual situation: How old is your email address? Have you been in a data breach? How freely have you shared your contact information online? How careful are you about what you click? How much spam is "too much" for you to tolerate? Your answers will shape which strategies matter most.
