How to Block Unwanted Emails in Yahoo Mail

Blocking unwanted emails in Yahoo Mail stops specific senders from reaching your inbox, reducing spam and clutter. This guide covers blocking individual addresses, domains, and managing your blocked list. You’ll need a Yahoo Mail account and access to its settings—no other tools are required.

What You’ll Need

• A Yahoo Mail account (free or paid)
• Access to the email you want to block (or the sender’s address)
• A web browser or the Yahoo Mail app (steps differ slightly)

Step-by-Step

On the Yahoo Mail Website (Desktop)

1. Log in to your Yahoo Mail account at mail.yahoo.com.
2. Open the email from the sender you want to block. If you don’t have an email, skip to the settings method below.
3. Click the three-dot menu (⋯) located at the top-right of the email pane, next to the Reply and Forward icons.
4. Select “Block” from the dropdown menu. A confirmation pop-up will appear.
5. Choose “Block” again to confirm. Yahoo will move the email to your Spam folder and add the sender to your blocked list.

If you want to block a sender without opening an email, use Settings:

6. Click the gear icon (⚙) in the top-right corner, then select “More Settings”.
7. Go to “Security and privacy” in the left sidebar.
8. Click “Blocked addresses”.
9. Click “Add address” or the “+” icon.
10. Enter the email address (e.g., spam@example.com) or the domain (e.g., example.com) you want to block.
11. Click “Save” to apply the block.

On the Yahoo Mail App (Mobile)

1. Open the Yahoo Mail app on your phone or tablet.
2. Open the email from the sender you want to block.
3. Tap the three-dot menu (⋯) in the top-right corner of the email screen.
4. Tap “Block” from the menu.
5. Confirm by tapping “Block” again. The sender is now blocked.

Common Mistakes

• Blocking the wrong address: Some senders use multiple addresses. Make sure you block the exact address that appears in the “From” field, not just the display name.
• Blocking the entire domain when you only want one sender: If you block a domain like “example.com”, all emails from that domain are blocked, which may include legitimate messages.
• Forgetting to unblock after a mistake: If you accidentally block someone, you need to remove them from your blocked list—just deleting the email won’t undo the block.
• Not checking spam after blocking: Blocked emails go to your Spam folder. If you don’t check it, you might miss an important email that was incorrectly blocked.

Tips

• Use filters for more control: Instead of blocking, you can create a filter to automatically delete or archive emails from a sender. Go to Settings → More Settings → Filters, then create a new filter.
• Block domains to stop entire companies: If you receive spam from many addresses at the same domain (e.g., “@spamdomain.com”), block the domain itself.
• Report spam as well: Blocking doesn’t always train Yahoo’s spam filter. Use the “Spam” button on emails to help Yahoo learn what you consider unwanted.
• Check your blocked list regularly: Review your blocked addresses every few months to ensure you haven’t blocked someone you now need.

Troubleshooting

Blocked emails still appear in your inbox: This can happen if the sender uses a different address or if the block hasn’t propagated yet. Wait a few minutes, then check the sender’s address. If it’s different, block that new address. Also, ensure you saved the block correctly in Settings.

You can’t find the “Block” option: On the desktop, the three-dot menu might be hidden if the email pane is narrow. Expand the window or click the “More” icon (three horizontal lines) in the top toolbar. On mobile, make sure you’re viewing the full email, not just the preview.

Blocking a domain doesn’t work: Yahoo’s domain blocking may not be case-sensitive, but ensure you’re entering the domain correctly (e.g., “example.com” not “www.example.com”). Also, some senders use subdomains (like “mail.example.com”)—you may need to block the parent domain.

You want to unblock someone: Go to Settings → Security and privacy → Blocked addresses. Find the address, click the “X” next to it, and confirm. It may take a few minutes for the unblock to take effect.

Blocked sender still appears in your spam folder: That’s normal. Blocked emails are moved to Spam, not deleted. You can delete them manually or set up a filter to automatically delete them.

Frequently Asked Questions

Does blocking an email sender in Yahoo Mail notify them?

No, the sender is not notified that you blocked them. They will still see their email as sent, but you won’t receive it in your inbox.

Can I block a sender from the Yahoo Mail app on my phone?

Yes, the mobile app has a “Block” option in the three-dot menu when viewing an email. The process is similar to the desktop version.

What happens to emails from a blocked sender?

Emails from blocked addresses are automatically moved to your Spam folder. They are not delivered to your inbox and are typically deleted after a certain period, usually 30 days.

Can I block a whole domain, like “@example.com”?

Yes, you can enter a domain name (e.g., “example.com”) in the blocked addresses list. This will block all emails from that domain.

How do I see my list of blocked addresses?

Go to Settings (gear icon) → More Settings → Security and privacy → Blocked addresses. There you’ll see all the addresses and domains you’ve blocked.

If I unblock someone, will their old emails come back?

No, unblocking only affects future emails. Emails that were moved to Spam during the blocking period will remain in Spam unless you manually move them to your inbox.
