The fastest way to block an email address

Open the email from the person you want to block. Look for the three dots (⋯) in the top right corner of the message and click it. A menu will appear with several options — select Block. Yahoo Mail will then move all future emails from that address to your Spam folder automatically.

That is the complete process. Once you block someone, you will not see their messages in your inbox, and they will not receive a notification that you blocked them. If you change your mind later, you can unblock them from your blocked senders list.

Key Takeaways

  • The block button is in the three-dot menu at the top right of any email message.
  • Blocked emails go to your Spam folder, not deleted, so you can review them if needed.
  • You can view and manage your entire blocked senders list in Yahoo Mail settings under the Privacy tab.
  • Blocking someone does not delete their past emails — only stops new ones from reaching your inbox.
  • The person you block will not know they are blocked and will not receive a bounce-back message.

Blocking from the sender's name or address

You do not have to open an email to block someone. If you see an address in your inbox list that you want to block, right-click on the sender's name. A context menu will pop up with a Block option. Click it, and that sender is blocked when ready.

This method works the same way as blocking from inside the email — future messages land in Spam. It is useful when you want to block someone without reading their message first. On a Mac, use Control+click instead of right-click to bring up the same menu.

Finding and managing your blocked senders list

To see everyone you have blocked, go to the settings gear icon in the top right corner of Yahoo Mail and select Settings. Click the Privacy tab on the left side. You will see a section called Blocked addresses with a list of every sender you have blocked.

From this list, you can unblock anyone by clicking the X next to their name. You can also add an email address to your blocked list manually without waiting for them to send you something first. Type the address into the text box under "Blocked addresses" and click Add. This is helpful if you know someone's address and want to prevent their emails before they arrive.

What happens to blocked emails

When you block someone, their emails do not disappear — they go to your Spam folder instead of your inbox. This means you can still find and read them if you need to, but they will not clutter your main inbox or trigger notifications on your device.

If a blocked sender uses a different email address, those messages will not be blocked automatically. Blocking works on a per-address basis, so someone with multiple email accounts can still reach you unless you block each address separately. Check your Spam folder occasionally to make sure important messages are not landing there by mistake.

Blocking on mobile devices

On the Yahoo Mail app for iPhone or Android, open the email you want to block. Tap the three dots in the top right corner and select Block sender. The process is identical to the desktop version — the sender goes to your blocked list and their future emails land in Spam.

You can also manage your blocked list on mobile by going to the menu (three horizontal lines), selecting Settings, then Privacy. The blocked addresses section works the same way as on a computer. Changes you make on your phone sync automatically to your Yahoo Mail account on other devices.

Blocking versus reporting spam

Blocking and reporting are two different actions. When you block someone, only their emails stop reaching your inbox. When you report as spam, you tell Yahoo Mail that the sender is sending unwanted bulk email, which helps Yahoo improve its spam filters for all users.

You can do both at once — report an email as spam and then block the sender. The report helps Yahoo's systems, while the block protects your inbox when ready. If you are receiving repeated unwanted emails from the same address, blocking is usually the faster solution for your own inbox.

Frequently Asked Questions

Will the person I block know that I blocked them?

No. The person will not receive any notification, bounce-back message, or indication that you blocked them. Their emails will straightforward disappear into your Spam folder without their knowledge.

Can I block an entire domain instead of just one email address?

Yahoo Mail does not have a built-in feature to block entire domains at once. You have to block individual email addresses. If you are receiving spam from many addresses at the same domain, you can block them one at a time or report them as spam to help Yahoo's filters improve.

What if someone I blocked sends me an email from a different address?

The block only applies to the specific email address you blocked. If the sender uses a different address, those emails will reach your inbox normally. You would need to block each address separately.

Can I unblock someone and then block them again?

Yes. Go to Settings, select Privacy, find the person in your blocked addresses list, and click the X to unblock them. You can block them again anytime using the same process.

Do blocked emails get deleted, or can I still read them?

Blocked emails are not deleted — they go to your Spam folder. You can open your Spam folder anytime to read or review messages from blocked senders if you need to.
