The fastest way to reduce spam is to unsubscribe from legitimate mailing lists and report actual spam

Most spam falls into two categories: marketing emails you signed up for but no longer want, and unsolicited junk from people trying to scam you or sell you something. The first type has an unsubscribe link at the bottom — it actually works, and using it removes you from that sender's list. The second type should be reported to your email provider, which trains its filters to catch similar messages in the future. Do both consistently and your inbox improves within weeks.

The unsubscribe link is usually in tiny gray text at the very bottom of a marketing email. Click it, and you will land on a page asking you to confirm. Complete that step. If you delete the email without unsubscribing, you stay on the list. If the unsubscribe link is broken or missing, that is a sign the sender is not legitimate — report it to your email provider instead of trying to unsubscribe.

Reporting spam trains your email provider's filter. In Gmail, click the three dots next to the email and select "Report spam." In Outlook, click the three dots and choose "Junk" then "Phishing." In Apple Mail, click the flag icon and select "Mark as Junk." Each report helps the system recognize similar messages from other senders.

Key Takeaways

  • Unsubscribe links at the bottom of marketing emails actually work and remove you from that sender's list permanently.
  • Report unsolicited spam to your email provider using the built-in spam or phishing button, which trains the filter to catch similar messages.
  • Never reply to spam, click links in suspicious emails, or confirm your email address — these actions tell spammers your address is active.
  • Use your email provider's filtering rules to automatically sort emails from certain senders into spam or a separate folder.
  • Create a separate email address for online shopping, signups, and forms to keep your main inbox cleaner.

Why your email address is on spam lists in the first place

Your email address ends up on spam lists through several common routes. You may have signed up for a newsletter or created an account on a website, and that company sold or shared your address with marketers. You may have entered your email in a form at a store, on a survey, or in a contest. Spammers also use software to guess common email formats and send to thousands of addresses at once, hoping some are real.

Once your address is on a list, it stays there unless you unsubscribe. Spammers also trade lists with each other, so one source of spam can lead to many. The older your email address, the more lists it has accumulated. This is why people with email addresses they have had for ten or fifteen years often receive far more spam than those with newer addresses.

How to use filters and rules to sort spam automatically

Your email provider lets you create rules that automatically move emails from certain senders into spam or a separate folder. This does not stop the email from arriving, but it keeps your inbox clean so you see only the messages you want.

In Gmail, open an email from a sender you want to filter. Click the three dots and select "Filter messages like these." Choose what to do with future emails from that sender — you can send them to spam, archive them, or move them to a label. In Outlook, right-click an email and select "Junk" then "Block Sender," which sends future emails from that address to your junk folder. In Apple Mail, select an email and go to Mail menu, then "Junk Mail Options," where you can set rules based on sender, subject line, or content.

You can also create rules based on keywords. If you keep receiving emails with "weight loss" or "limited offer" in the subject line, create a rule that sends anything with those words to spam. Be careful not to make the rule too broad — if you block anything with "order" in the subject, you might accidentally filter legitimate receipts from online stores.

What not to do when you receive spam

Never reply to spam, even to say "remove me from your list." A reply tells the spammer your email address is active and monitored, which makes it more valuable. They will sell it to other spammers or send you more messages.

Never click links or read attachments from emails you do not recognize. Links in spam can install malware on your computer or take you to a fake website designed to steal your password or payment information. Attachments can contain viruses. If you are unsure whether an email is real, go directly to the company's website by typing the address into your browser instead of clicking a link in the email.

Never confirm your email address by clicking "verify your email" or "confirm your account" in a suspicious email. This tells spammers the address is real. If you think the email might be legitimate — for example, from your bank — call the bank's customer service number on the back of your card instead of clicking anything in the email.

Creating a separate email address for online shopping and signups

One of the most effective ways to keep spam out of your main inbox is to use a second email address for online shopping, newsletter signups, and forms. Your primary email stays clean because only people you know and trusted services have it. Your secondary address receives all the marketing mail, and you check it only when you need to.

Most email providers let you create multiple free accounts. Gmail, Outlook, and Yahoo all allow you to set up as many addresses as you want. Use your main address only for personal contacts, banking, and services you trust. Use the secondary address for retail websites, social media, online contests, and any form that asks for your email but is not essential to your life.

You can also use email masking services like Hide My Email (built into Apple Mail and iCloud) or temporary email services like Temp Mail or 10 Minute Mail. These create a unique address for each signup that forwards to your real inbox. When you stop using the service, you can disable the forwarding and never hear from them again. This is useful for one-time signups or services you are not sure about.

Understanding the difference between spam and phishing

Spam is unwanted marketing email — newsletters you did not sign up for, offers to buy things, ads for weight loss pills. It is annoying but usually not dangerous. Phishing is a scam designed to steal your information. A phishing email pretends to be from your bank, PayPal, Amazon, or another service you use, and asks you to "verify your account," "confirm your password," or "update your payment method."

Phishing emails often look very similar to real emails from the company, but they have small differences. The sender's email address might be slightly wrong — for example, "amaz0n.com" instead of "amazon.com." The email might ask you to click a link and log in, but the link goes to a fake website that looks real but is not. The email might have spelling or grammar mistakes, or ask for information the real company would never request by email.

If you receive a phishing email, report it to your email provider when ready. Do not click any links or reply. If you are worried the email might be real, call the company directly using the phone number on your statement or their official website. Never use a phone number from the email itself.

When to consider changing your email address

If your inbox receives dozens of spam emails every day even after unsubscribing and reporting, and your email address is very old or was part of a data breach, you might consider creating a new email address and migrating to it. This is a bigger step than filtering, but it can give you a fresh start.

Before you switch, check whether your email address has been exposed in a data breach. Visit Have I Been Pwned (haveibeenpwned.com) and enter your email address. If it shows up in a breach, that explains why you are receiving so much spam — your address was stolen and sold. In that case, a new address will help.

If you decide to switch, create a new email address and gradually update your important accounts — your bank, email provider, insurance company, employer, and any services you use regularly. Forward emails from your old address to your new one for a few months so you do not miss anything important. After that period, you can close the old address or let it sit unused.

Frequently Asked Questions

Does unsubscribing from spam actually work?

Unsubscribing works only if the sender is a legitimate business. Marketing emails from real companies have working unsubscribe links and will remove you within a few days. Emails from scammers or spammers often have fake unsubscribe links that do nothing or confirm your address is active. If the unsubscribe link is broken or missing, report the email as spam instead.

Is it safe to use temporary email addresses?

Yes. Temporary email services create a unique address that forwards to your real inbox for a set time, then stops working. They are useful for signups you do not trust or one-time services. The downside is you cannot receive password reset emails or account notifications after the temporary address expires, so use them only for services you do not plan to return to.

What should I do if I accidentally clicked a link in a phishing email?

If you clicked a link but did not enter your password or payment information, you are probably fine — just close the page. If you entered your password, change it when ready on the real company's website. If you entered credit card or banking information, contact your bank or credit card company right away. They can monitor your account and issue a new card if needed.

Why do I still get spam after unsubscribing?

You may be receiving spam from multiple senders. Unsubscribing removes you from one company's list, but if your address is on ten lists, you will still receive nine. Keep unsubscribing from each sender and reporting the ones without working unsubscribe links. It takes time, but your inbox will improve as you work through them.

Can I block all emails from a certain domain?

Yes, but be careful. You can create a filter rule to send all emails from a domain (like "spammer.com") to spam. However, if you block a domain, you will also block legitimate emails from that domain if someone you know uses that email address. It is safer to block individual senders or use keywords in the subject line instead.
