The fastest way to reduce spam is to unsubscribe, filter, and report
Most spam falls into three categories: marketing emails you signed up for but no longer want, unsolicited bulk mail from companies you never contacted, and phishing attempts designed to steal your information. Each one has a different solution, and using all three together works better than any single method.
Start by unsubscribing from legitimate marketing emails — the ones with an "Unsubscribe" link at the bottom. This removes you from the sender's mailing list. Then set up filters in your email provider to automatically sort remaining unwanted mail into a spam folder. Finally, report actual spam and phishing attempts to your email provider so their systems learn to block similar messages for everyone.
The reason this matters: spam clutters your inbox, makes it harder to find real messages, and phishing emails can trick you into giving away passwords or money. A clean inbox also makes it easier to spot when something important arrives.
Key Takeaways
- Unsubscribe from legitimate marketing emails using the link at the bottom of the message — this is faster than filtering and actually removes you from the sender's list.
- Create filters or rules in Gmail, Outlook, Yahoo, or Apple Mail to automatically move unwanted emails to spam based on sender, subject line, or keywords.
- Report spam and phishing emails to your email provider using the "Report Spam" or "Report Phishing" button so their systems block similar messages.
- Never reply to spam, click links in suspicious emails, or give out your email address to unknown websites — these actions confirm your address is active and lead to more spam.
- Use a secondary email address for online shopping, signups, and forms so your primary inbox stays cleaner.
How to unsubscribe from marketing emails
Legitimate companies are required by law to include an unsubscribe option in their marketing emails. Look at the very bottom of the email — you will see a small link that says "Unsubscribe," "Manage Preferences," or "Stop Receiving These Emails." Click it and follow the steps to remove yourself from their mailing list.
This works because the sender actually removes your address from their database. It is faster than filtering and prevents future emails from that company. Unsubscribing takes 30 seconds and is the first thing to do when you get unwanted marketing mail.
If you cannot find an unsubscribe link, the email is likely spam rather than a legitimate marketing message. Do not reply to it — just delete it and move on to filtering or reporting.
Setting up filters and rules to catch spam automatically
Filters work by catching emails that match rules you set and moving them straight to spam or a folder you choose. Every major email provider has this feature, though the name and location differ slightly.
In Gmail: Open an unwanted email, click the three dots in the top right, and select "Filter messages like these." You can filter by sender, subject line, or keywords. Choose "Delete" or "Skip the Inbox" to send matching emails to spam automatically. You can also create a filter from scratch by going to Settings > Filters and Blocked Addresses > Create a New Filter.
In Outlook: Right-click an unwanted email and select "Junk" > "Block Sender" to send all future emails from that address to your junk folder. For more control, go to Settings > Mail > Junk Email and add senders or domains to the "Blocked Senders" list. You can also create rules by going to Settings > Mail > Rules and set up automatic actions based on sender, subject, or message content.
In Yahoo Mail: Click the three dots on an unwanted email and select "Block Sender." To create custom filters, go to Settings > Filters and create a new filter by sender, subject, or content. Yahoo will automatically move matching emails to spam.
In Apple Mail: Select an unwanted email and go to Mail > Junk Mail > Mark as Junk. Apple learns from your choices over time. For manual rules, go to Mail > Preferences > Rules and create a rule that moves emails matching certain criteria to your junk folder.
Reporting spam and phishing to your email provider
When you report spam or phishing, you are telling your email provider's system that a message is unwanted or dangerous. This helps their filters improve and protects other users. Most email providers have a "Report Spam" or "Report Phishing" button built into each email.
In Gmail: Open the email, click the three dots, and select "Report Phishing" or "Report Spam." Gmail moves the message to spam and uses it to train its filters.
In Outlook: Click the three dots on an email and select "Junk" > "Report Phishing" or "Report Spam." Outlook sends the report to Microsoft and blocks similar messages.
In Yahoo Mail: Click the three dots and select "Report Spam" or "Report Phishing." Yahoo flags the sender and improves its spam detection.
In Apple Mail: Select an email and go to Mail > Junk Mail > Mark as Junk. You can also forward suspicious emails to your provider's phishing report address (usually phishing@[provider].com).
Reporting takes five seconds and makes a real difference. Do this for phishing emails especially — they are designed to steal passwords or money, and reporting them protects other people using the same provider.
Why you should never reply to spam or click unknown links
When you reply to spam, click a link in a suspicious email, or enter your information on an unknown website, you are confirming to the sender that your email address is active and monitored. This leads to more spam, not less. Spammers sell active addresses to other spammers, and your inbox gets worse.
Phishing emails are especially dangerous because they look like they come from banks, PayPal, Amazon, or other trusted companies. They ask you to "verify your account," "confirm your password," or "update your payment method." Clicking the link takes you to a fake website that steals whatever you type. Real companies never ask for passwords or sensitive information by email.
The safest approach: if an email looks suspicious, do not click anything. Delete it, report it, or go directly to the company's official website by typing the address yourself into your browser.
Using a secondary email address to reduce spam at the source
One of the best ways to keep your main inbox clean is to use a separate email address for online shopping, newsletter signups, social media, and forms. This keeps your primary address off mailing lists and away from data breaches that expose email addresses to spammers.
You can create a free secondary email in Gmail, Outlook, Yahoo, or Apple Mail in under a minute. Use it for anything that is not work or personal communication. When spam starts piling up in the secondary address, you can delete it, create a new one, or straightforward ignore it — your main inbox stays clean.
This is not foolproof, but it significantly reduces the amount of unwanted mail you see in your primary inbox. Many people find it worth the small effort of managing two addresses.
What to do if spam is coming from a hacked account
Sometimes spam comes from someone you know — a friend, family member, or colleague whose email account has been hacked. The sender's name appears real, but the email is spam or a phishing attempt. Do not click links or read attachments, even if you recognize the sender.
Instead, contact the person directly through another method — a phone call, text message, or in person — and let them know their account may be compromised. They should change their password when ready and check their sent folder to see what was sent from their account.
Report the email to your provider as spam or phishing. Do not reply to it. The hacker is using the account to send mail to everyone in that person's contact list, and reporting it helps protect others.
Frequently Asked Questions
Does marking an email as spam actually stop future emails from that sender?
Marking as spam helps your email provider's system learn, but it does not always stop the sender if they use different addresses or domains. Unsubscribing is more effective for legitimate companies. For actual spam, combining reporting with filters gives you the best protection.
Is it safe to click "Unsubscribe" on emails I do not recognize?
Unsubscribe links from legitimate companies are safe. However, if an email looks suspicious or you have no memory of signing up, do not click anything — just delete it and report it as phishing. Real companies include clear unsubscribe links; scammers often hide them or make them look fake.
Can I block an entire domain or company from sending me emails?
Yes. In Gmail, Outlook, and Yahoo, you can add a domain (like @example.com) to your blocked senders list, and all emails from that domain will go to spam. In Apple Mail, you can create a rule that blocks any sender from a specific domain. This is useful if one company keeps sending mail from multiple addresses.
What should I do if I accidentally clicked a phishing link?
Change your password when ready if you entered it on the fake website. If you gave credit card or banking information, contact your bank or credit card company right away. Monitor your accounts for suspicious activity. You can also report the phishing email to your email provider and the company being impersonated.
Why do I still get spam even after unsubscribing and filtering?
Your email address may have been sold to other companies, exposed in a data breach, or added to spam lists by bots that harvest addresses from websites. Spam never stops completely, but unsubscribing, filtering, and reporting reduce it significantly over time. Using a secondary email for signups prevents new spam from reaching your main inbox.
