Block a sender in Yahoo Mail with one click

You can block an email sender in Yahoo Mail in seconds. Open the message from the person you want to block, click the three-dot menu icon in the top right of the email, and select Block. Yahoo will move that sender's future emails to your Spam folder automatically. You can also block a sender by right-clicking their name in your inbox and choosing Block from the menu.

Once you block someone, you won't see their emails in your inbox anymore — they go straight to Spam. If you change your mind later, you can unblock them by going to your blocked senders list in Settings.

Key Takeaways

  • Blocked senders' emails go to your Spam folder, not your inbox, and you won't get notifications about them.
  • You can block a sender from any email they send you by clicking the three-dot menu and selecting Block.
  • Yahoo stores your blocked senders list in Settings under Privacy, where you can view or remove blocks anytime.
  • Blocking someone in Yahoo Mail only affects your account — they won't know they're blocked and can still send you messages.

Block a sender from an open email

This is the fastest way to block someone. Open any email from the person you want to block. At the top right of the email, you'll see three horizontal dots (the menu icon). Click it.

A dropdown menu will appear with several options. Look for and click Block. Yahoo will confirm that you've blocked this sender. From now on, any email from that person will skip your inbox and go straight to your Spam folder.

If you accidentally block someone, you can undo it immediately — Yahoo usually shows an "Undo" button right after you block. If you miss that window, you can unblock them later through your Settings.

Block a sender from your inbox list

You don't have to open an email to block someone. In your inbox, find the email from the sender you want to block. Right-click on their name or the email subject line.

A context menu will pop up. Select Block sender from the options. The email will move to Spam, and future emails from that person will do the same. This method works the same way as blocking from an open email — the sender just goes to your blocked list either way.

Find and manage your blocked senders list

Yahoo keeps a record of everyone you've blocked. To see this list, click the gear icon in the top right of your Yahoo Mail page and select Settings. In the left sidebar, click Privacy.

Under the Privacy section, you'll see a list called Blocked addresses. This shows every sender you've blocked. If you want to unblock someone, find their email address in the list and click the X or Remove button next to it. They'll be unblocked immediately, and their emails will start appearing in your inbox again.

You can also add someone to your blocked list manually from this page without waiting for them to send you an email first. Just type their email address into the field and click Add.

What happens when you block someone

When you block a sender in Yahoo Mail, their emails don't disappear — they go to your Spam folder instead. You won't see notifications for their messages, and they won't appear in your inbox count. If you ever need to read a blocked email, you can find it in Spam, but you have to go looking for it.

The person you blocked won't receive any notification that you've blocked them. They can still send you emails, but those emails will land in Spam. From their perspective, they have no way of knowing whether you received their message, read it, or blocked them.

Blocking is different from unsubscribing. If you block a sender, all their emails go to Spam. If you unsubscribe from a mailing list, you're asking to be removed from that list entirely — but you can still receive emails from that sender if they send you a direct message.

Unblock a sender if you change your mind

Go back to Settings and click Privacy in the left sidebar. Find the sender's email address in your Blocked addresses list. Click the X or Remove button next to their name.

Once you unblock them, their emails will start arriving in your inbox again. Any emails they sent while they were blocked will still be in your Spam folder — unblocking doesn't move old messages back to your inbox. You'll have to move those manually if you want to see them.

Block emails by subject line or sender domain

If you're getting spam from many different addresses at the same domain (like multiple addresses ending in @spamsite.com), blocking each one individually takes time. Instead, you can create a filter to handle them all at once.

Go to Settings and click Filters in the left sidebar. Click Add new filter. In the "From" field, type the domain you want to block — for example, @spamsite.com. Under "Then", select Delete or Move to Spam. Click Save. Now any email from that entire domain will go straight to Spam or be deleted.

You can also create filters based on subject lines or keywords. If you keep getting emails with "Buy now" or "Limited offer" in the subject, you can filter those the same way. This is more powerful than blocking individual senders because it catches variations and new addresses from the same source.

Frequently Asked Questions

Can I block emails from a whole company or domain?

Yes, but you'll need to use Filters instead of the Block button. Go to Settings, click Filters, and create a new filter with the domain (like @company.com) in the "From" field. Set it to move to Spam or delete. This catches all emails from that domain, even if they come from different people.

Will the person I blocked know I blocked them?

No. They won't receive any notification. Their emails will still send successfully from their perspective — they just won't reach your inbox. They have no way to know whether you received, read, or blocked their messages.

Can I block emails on my phone?

Yes. In the Yahoo Mail app on your phone, open an email from the sender you want to block. Tap the three-dot menu icon and select Block. The process is the same as on a computer. You can also manage your blocked list in the app's Settings under Privacy.

What's the difference between blocking and reporting spam?

Blocking sends a sender's emails to your Spam folder. Reporting spam does the same thing but also tells Yahoo that the sender is sending unwanted messages, which helps Yahoo identify and stop spam for other users. If you're getting unsolicited bulk email, report it as spam instead of just blocking.

Can I recover emails from a blocked sender if I unblock them?

Emails that arrived while someone was blocked stay in your Spam folder even after you unblock them. Unblocking only stops future emails from going to Spam — it doesn't move old messages back to your inbox. You'll have to find them in Spam and move them manually if you want to read them.
