The fastest way to reduce spam is to use your email provider's built-in filters and mark unwanted mail as spam
Most email providers — Gmail, Outlook, Yahoo Mail — filter spam automatically, but they work better when you help them. Every time you mark an email as spam or junk, you train the filter to catch similar messages in the future. The filter learns from your choices, so a message that looks like spam to the system but isn't spam to you can be moved back to your inbox, and the system adjusts.
Start by opening your spam or junk folder (Gmail calls it "Spam", Outlook calls it "Junk Email"). Look for messages that are actually spam — not legitimate mail that got sorted wrong. Select them and mark them as spam. Do this for a week or two, and you will notice fewer unwanted messages reaching your inbox. The filter gets smarter as it sees what you reject.
If spam is still heavy after a week, move to the next steps. But most people find that consistent marking reduces the problem significantly without needing anything else.
Key Takeaways
- Mark unwanted emails as spam in your inbox so your email provider's filter learns what you do not want to see.
- Never reply to spam, click unsubscribe links you do not trust, or confirm your email address by responding — these tell spammers your address is active.
- Use the unsubscribe link only for mail from real companies you recognize, not for obvious spam or phishing attempts.
- Create a separate email address for online shopping, signups, and forms so spam does not reach your main inbox.
- Check your email provider's filter settings to move suspected spam automatically to a folder instead of your inbox.
Unsubscribe only from mail you actually signed up for
Legitimate companies include an unsubscribe link at the bottom of marketing emails — this is required by law in most places. If you recognize the sender and remember signing up, clicking unsubscribe usually works. The company removes your address from their list, and you stop hearing from them.
Do not click unsubscribe on obvious spam, phishing attempts, or mail from senders you do not recognize. Clicking the link tells spammers your email address is real and monitored, which makes your address more valuable to sell to other spammers. If you do not recognize the sender, mark it as spam instead.
The safest approach: if you are unsure whether the sender is real, mark it as spam. If it turns out to be legitimate mail, you can find it in your spam folder and move it back. But confirming your address to a spammer is harder to undo.
Create a separate email address for shopping and signups
Every time you enter your email address into a website, form, or online store, that address gets added to a list. Some companies sell these lists to other businesses. Over time, your main email address collects spam from dozens of sources you never directly contacted.
Create a second email address — through Gmail, Outlook, or Yahoo — and use it only for shopping, newsletter signups, and forms. Keep your main address for people you actually know and services you actively use. Spam will still reach the secondary address, but your primary inbox stays cleaner.
You can check the secondary address once a week or less often. If a company sends something important (like a shipping notification), you will see it there. Everything else can sit in spam.
Adjust your email provider's filter settings
Gmail, Outlook, and Yahoo all have filter settings you can customize. The exact steps differ by provider, but the idea is the same: tell the system to move suspected spam to a folder automatically instead of showing it in your inbox.
In Gmail, open Settings (the gear icon), go to Filters and Blocked Addresses, and create a new filter. You can filter by sender, subject line, or keywords. For example, you might filter all mail containing the word "viagra" or from a specific sender. Choose "Skip the Inbox (Archive)" or "Delete it" so the mail never reaches you.
In Outlook, go to Settings, then Mail, then Junk Email. You can add senders to a blocked list, and Outlook will automatically move their mail to junk. You can also set the filter level to "Safe" or "Strict" — strict catches more spam but sometimes catches legitimate mail too.
Start with the default filter level. If spam is still heavy after two weeks of marking messages, move to a stricter setting. Check your spam folder occasionally to make sure real mail is not getting caught.
Never reply to spam or confirm your address
Spammers often send mail with a message like "Reply to confirm your address" or "Click here to unsubscribe" — both are traps. Replying or clicking tells them your address is active and monitored. Your address then gets sold to other spammers or used for more targeted attacks.
The same applies to messages asking you to "verify your account" or "confirm your identity" by clicking a link or entering information. These are usually phishing attempts designed to steal your password or personal data. Real companies do not ask you to confirm sensitive information by email.
If you are unsure whether a message is real, do not click the link in the email. Instead, go directly to the company's website (type the address into your browser yourself) and log in. If there is a real problem with your account, you will see a message when you log in. If there is nothing, the email was spam.
Report phishing and scam emails to your provider
Some spam is not just annoying — it is phishing, which means the sender is trying to steal your password, credit card number, or personal information. These emails often pretend to be from your bank, PayPal, Amazon, or another service you use.
Most email providers have a "Report phishing" or "Report suspicious" option. In Gmail, click the three dots on the email and choose "Report phishing". In Outlook, click the three dots and choose "Report". This tells the provider's security team about the attempt, and they use the information to improve their filters.
Do not click any links in a phishing email, and do not reply. Just report it and delete it. If you are worried the email might be real, contact the company directly using a phone number or website you find yourself — not a number or link from the email.
Use a spam filter service if your provider's filter is not enough
If you have tried marking spam, adjusting filters, and using a secondary email address and spam is still overwhelming, a third-party filter service may help. Services like SaneBox, Clean Email, or Unroll.me work with your existing email account and add an extra layer of filtering.
These services scan your inbox and sort mail into categories — newsletters, promotions, notifications, and so on. You can then delete entire categories at once or move them to a folder. They also let you unsubscribe from multiple newsletters in bulk.
The trade-off is that you are giving a third-party company access to read your emails so they can sort them. Most of these services are legitimate and have privacy policies, but you should read their terms before signing up. For many people, the built-in filters and a secondary email address are enough, so a paid service is not necessary.
Frequently Asked Questions
Is it safe to click unsubscribe links?
Unsubscribe links are safe if the email is from a real company you recognize. If you do not know the sender or the email looks like obvious spam, mark it as spam instead of clicking unsubscribe. Clicking unsubscribe on spam tells spammers your address is active.
What should I do if I get an email asking me to verify my bank account?
Do not click the link in the email. Go directly to your bank's website or call the number on the back of your card and ask if they sent it. Banks do not ask you to verify sensitive information by email. If the email is real, the bank will tell you when you call.
Can I get my email address removed from spam lists?
Once your address is on a spam list, it is difficult to remove completely. Marking spam, using filters, and creating a secondary address are more effective than trying to get off lists. Some services claim to remove your address from lists, but most are scams.
Does marking spam as spam actually work?
Yes, but it takes time. After a week or two of marking unwanted mail, your email provider's filter learns your preferences and catches more spam automatically. The filter works better the more you use it, so consistency matters.
Should I use a VPN or email encryption to stop spam?
A VPN and email encryption protect your data in transit, but they do not stop spam from reaching your inbox. Spam filtering, marking unwanted mail, and using a secondary email address are more effective for reducing spam volume.
