Spam is not just annoying. It buries the emails you care about, and some of it is built to trick you. You cannot make spam disappear completely, but you can cut it down a lot. Here is what works, in order.
1. Use the unsubscribe link, but only for real companies
If the email comes from a store or service you recognize, unsubscribe. Legitimate senders have to honor it:
- In the US, the CAN-SPAM Act requires marketers to include a way to opt out and to stop emailing you within 10 business days.
- In the UK, marketing emails generally need your consent in the first place, under the Privacy and Electronic Communications Regulations (PECR).
- Gmail and Yahoo require large senders to offer one-click unsubscribe, so you will often see an “Unsubscribe” button right next to the sender’s name.
Do not click unsubscribe in emails from senders you do not know. With real spammers, clicking only confirms that your address is active.
2. Mark spam as spam, do not just delete it
Pressing Report spam (Gmail) or Report > Report junk (Outlook) teaches your email provider’s filter what to catch. Deleting the email teaches it nothing. A few reports a week make a visible difference within a month.
3. Block persistent senders
If one sender keeps coming back, block the address. In Gmail, open the email, press the three dots and choose Block. In Outlook, use Block sender. Spammers change addresses often, so this works best for one specific, stubborn sender.
4. Create filters for the gray area
Some emails are not spam but still clutter your inbox: newsletters you skim once a month, receipts, notifications. Filters can move them to a folder automatically, so your main inbox only shows what needs you.
5. Report phishing to the right place
Phishing emails pretend to be your bank, a delivery company or a tax office. Besides reporting them in your inbox:
- US: forward them to the Anti-Phishing Working Group at
[email protected], as the Federal Trade Commission recommends. - UK: forward them to the National Cyber Security Centre at
[email protected].
Never enter a password or card number from a link in an unexpected email. Go to the website yourself instead.
6. Stop giving your real address to everyone
Most spam starts with a sign-up: a coupon, a free trial, a Wi-Fi login, a contest, a one-time download. Your address then gets shared, sold or leaked.
This is the step that prevents spam instead of cleaning it up. For anything you only need once, use a temporary email address. You receive the confirmation email, and when the timer ends the address and its emails are deleted. Nothing can reach your real inbox, because the website never had it.
7. Keep an eye on trackers
Many marketing emails contain invisible images that tell the sender when, and sometimes where, you opened them. That makes your address more valuable to them. Turn off automatic image loading in your email app, or read one-off emails in an inbox that blocks trackers.
8. Do not publish your address in plain text
Bots scan websites, forums and social profiles for anything that looks like an email address. If you must share it publicly, write it as name [at] example [dot] com, or use a contact form instead.
9. Check whether your address leaked
If spam suddenly jumps, your address may have been in a data breach. See our guide on how to check if your email was in a data breach and what to do next.
What not to do
- Do not reply to spam, not even to say “stop”.
- Do not buy “spam removal” services that promise to delete your address from every list. No one can do that.
- Do not abandon your main address unless it is truly overwhelmed. With the steps above, most inboxes calm down.
Summary
Unsubscribe from senders you know, report the rest as spam, and filter the clutter. Then cut spam off at the source: keep your real address for people and accounts you trust, and use a temporary email for everything else.
