The fastest way to stop an email is to unsubscribe or block the sender

Most legitimate companies include an unsubscribe link at the bottom of their emails — usually in small text. Click that link, and you'll be taken to a page where you can confirm you want to stop receiving messages from that sender. This works because the sender is legally required to honor it within 10 business days in the United States.

If there is no unsubscribe link, or if unsubscribing doesn't work after two weeks, use your email provider's block or report feature. In Gmail, open the email and click the three dots in the top right, then select "Block [sender]" or "Report spam". In Outlook, right-click the sender's name and choose "Block". In Apple Mail, select the email and click the Mail menu, then "Junk". Blocking prevents future emails from that address from reaching your inbox.

The difference matters: unsubscribe removes you from a mailing list that the sender controls. Blocking stops emails from a specific address at your email provider's level, even if the sender ignores your unsubscribe request.

Key Takeaways

  • Look for an unsubscribe link at the bottom of the email in small text, and click it to remove yourself from the sender's mailing list.
  • If unsubscribe doesn't work or doesn't exist, use your email provider's block feature to prevent that sender's emails from reaching your inbox.
  • Spam emails often come from addresses designed to look legitimate; blocking the actual sender address stops those specific messages.
  • Never reply to spam or click links in suspicious emails, as this confirms your address is active and can increase the volume you receive.
  • If a sender claims you must pay to unsubscribe or threatens legal action for unsubscribing, report the email to your provider as a scam.

Why unsubscribe links sometimes don't work

A sender might ignore your unsubscribe request for several reasons. They may have sold your address to another company, so you're now receiving mail from a different sender. They may be using a fake unsubscribe link that doesn't actually remove you — it just confirms your address is active, which can lead to more spam. Or the sender may be operating outside the United States and not subject to U.S. unsubscribe laws.

If you unsubscribe and still receive emails from the same sender after two weeks, that sender is likely breaking the law. At that point, blocking is more effective than unsubscribing again. Some email providers also let you report the sender for not honoring unsubscribe requests, which helps their spam filters learn to catch similar messages.

How to block senders in your email provider

Gmail: Open the email. Click the three dots (more actions) in the top right. Select "Block [sender name]". Future emails from that address go straight to spam. You can also mark the email as spam first, which offers a block option.

Outlook (web and desktop): Right-click the sender's name or address. Choose "Block". On mobile, swipe left on the email and tap the block icon. Blocked senders' emails move to your junk folder automatically.

Apple Mail: Select the email. Go to the Mail menu at the top of your screen and click "Junk". You can also right-click the sender and select "Add to VIP" or "Block Contact" depending on your version. On iPhone or iPad, swipe left on the email and tap "Trash", then "Block This Contact".

Yahoo Mail: Hover over the sender's name and click the block icon, or open the email and click the three dots, then "Block sender". Blocked senders go to spam automatically.

What to do if the sender keeps changing their address

Spammers sometimes send from slightly different addresses each time — for example, noreply@company.com, then noreply2@company.com, then support@company.com. Blocking individual addresses becomes tedious. Instead, look at the domain (the part after the @). If all the spam is coming from variations of the same domain, you can often create a filter to block the entire domain at once.

In Gmail: Open one of the emails from that sender. Click the three dots and select "Filter messages like this". In the "From" field, you'll see the sender's address. Change it to just the domain — for example, change "noreply@spamcompany.com" to "spamcompany.com". Click "Create filter" and select "Delete it" or "Skip the inbox". Now any email from anyone at that domain will be filtered.

In Outlook: Go to Settings (the gear icon). Select "View all Outlook settings". Go to Mail > Junk email. In the "Blocked senders" section, add the domain name (for example, spamcompany.com). Emails from that domain will go to junk.

In Apple Mail: Go to Mail > Preferences (or Settings on Mac). Click Rules. Click "Add Rule". Set "From" contains the domain name, then set the action to "Move Message" to Junk. Click OK.

When to report instead of just blocking

Reporting an email to your provider as spam or phishing helps train their filters to catch similar messages for all users. You should report, not just block, if the email asks you to click a link and enter your password, claims you've won money you didn't enter, threatens legal action, or asks for payment to unsubscribe.

Reporting also matters if the email impersonates a real company you use — for example, an email that looks like it's from your bank but asks you to "verify your account". These are phishing attempts, and reporting them helps your provider identify the scam faster. In Gmail, click the three dots and select "Report phishing". In Outlook, click the three dots and select "Report". In Apple Mail, select the email and go to Mail > Report Junk Mail.

Do not reply to the email, click any links in it, or call any phone number it provides. Replying confirms your address is active and monitored, which increases the spam you'll receive.

How to reduce spam before it arrives

Your email address itself is the target. Once spammers have it, they keep using it. You can't stop them from trying, but you can make it harder for them to get your address in the first place.

When you sign up for websites, use a separate email address if possible — many providers let you create multiple addresses for free. If a website asks for your email and you're not sure you trust it, use a temporary email service like Temp Mail or 10 Minute Mail, which creates a disposable address that expires after a set time. This protects your main address from being sold to advertisers or spammers.

Avoid posting your email address on public websites, social media, or forums. Spammers use automated tools to scrape email addresses from public pages. If you must post it, write it as "yourname at company dot com" instead of "yourname@company.com" — humans can read it, but automated scrapers usually can't.

Be cautious about what you agree to when you sign up. Read the privacy policy or terms of service to see whether the company plans to share your address with third parties. Many legitimate companies do this, and it's legal — but it's also a reason you might receive more email than you expected.

Frequently Asked Questions

Is it safe to click unsubscribe links?

Unsubscribe links from legitimate companies are safe. However, if the email looks suspicious — poor grammar, unknown sender, asks for personal information — do not click the link. Instead, block the sender. Scammers sometimes use fake unsubscribe links to confirm your address is active.

What if I accidentally marked a legitimate email as spam?

In Gmail, go to the Spam folder, find the email, open it, and click "Report not spam". In Outlook, go to Junk, find the email, right-click it, and select "Not junk". In Apple Mail, select the email and go to Mail > Junk Mail > Not Junk. This trains your filter to recognize similar emails as legitimate in the future.

Can I unsubscribe from all emails at once?

No. You must unsubscribe from each sender individually or block them one at a time. Some email providers offer bulk actions — for example, you can select multiple emails from the same sender and block them together — but you cannot unsubscribe from all senders with a single action.

Why do I still get emails after blocking someone?

The sender may be using a different email address or domain. Check the sender's address carefully — it might look similar to the one you blocked but have a slight difference. If it's the same address, the block may not have taken effect yet; wait a few hours and check your spam folder to confirm the emails are being filtered there.

Should I reply to spam to ask them to stop?

No. Replying confirms your address is monitored and active, which often increases the spam you receive. Use unsubscribe or block instead. If the sender is operating illegally (for example, they ignore unsubscribe requests), replying won't help anyway.
