Blocking someone on Yahoo Mail stops their messages from reaching your inbox

When you block a contact on Yahoo Mail, their emails go straight to your spam folder instead of appearing in your inbox. You can block someone in two ways: from an open email, or from your contacts list. The block stays in place until you remove it — Yahoo does not automatically unblock people after a set time.

Blocked senders cannot see that they are blocked. They will not receive a bounce-back message or any notification. Their emails straightforward disappear from your view, though Yahoo stores them in your spam folder for 30 days before deleting them permanently.

Key Takeaways

  • Blocking takes 10 seconds and can be done from an open email or from your contacts list.
  • Blocked emails land in spam, not in a separate "blocked" folder, so you will need to check spam if you want to see what they sent.
  • You can unblock someone at any time by removing them from your blocked list in Settings.
  • Blocking is different from unsubscribing — blocking stops all mail from a person, while unsubscribing only removes marketing emails.

Block someone from an open email

Open any email from the person you want to block. Look at the top of the message, near the sender's name and address. Click the three dots (the menu icon) on the right side of that bar.

A dropdown menu will appear with several options. Select "Block [sender's name]" or "Block sender". Yahoo will when ready move that email to spam and add the sender to your blocked list. Any future emails from that address will go to spam automatically.

Block someone from your contacts list

Go to your Contacts page by clicking the grid icon in the top left of Yahoo Mail, then selecting Contacts. Find the person you want to block in your list and click their name to open their contact card.

Click the three dots menu on the contact card and select "Block contact". Yahoo will add them to your blocked list. If you have already received emails from this person, those messages will remain in your inbox — only new emails from them will go to spam.

Find and manage your blocked list

To see everyone you have blocked, go to Settings (the gear icon in the top right of Yahoo Mail). Select "Privacy" or "Blocked addresses" depending on your version of Yahoo Mail. You will see a complete list of all blocked senders.

To unblock someone, find their name or email address in this list and click the X or "Remove" button next to it. They will be unblocked when ready, and their emails will no longer go to spam. If they send you a message while you are unblocking them, that message may still land in spam — refresh your inbox after unblocking to see if anything arrives.

What happens to blocked emails

When someone you have blocked sends you an email, it goes directly to your Spam folder. You can still read it if you check your spam — blocking does not delete the message, it just hides it from your main inbox view. Yahoo keeps spam messages for 30 days, then deletes them permanently.

If you block someone and then later want to read their old emails, you can find them in your Spam folder. Unblocking them does not restore deleted messages, so if you have already emptied your spam folder, those emails are gone.

Blocking versus other ways to stop unwanted mail

Blocking is the strongest action you can take on a single sender. It stops all mail from that address and hides it from your inbox. Unsubscribing, by contrast, only removes you from marketing emails — it does not block personal messages from the same sender. If someone is sending you unwanted personal emails, blocking is the right choice.

If you receive a lot of similar spam from many different addresses, you may want to use Yahoo's spam filters instead. Filters let you automatically delete or sort emails based on keywords, sender domain, or subject line. Blocking works best for one specific person; filters work better for patterns of unwanted mail.

Frequently Asked Questions

Can someone tell if I have blocked them?

No. Blocked senders do not receive any notification, and their emails do not bounce back to them. They will straightforward notice that you are not replying to their messages, but Yahoo does not tell them they are blocked.

What if someone blocks me on Yahoo Mail?

If you are blocked, your emails will go to their spam folder without any indication to you. You will not receive a bounce-back message. The only way to know is if the person tells you directly or if you notice they never respond to your messages.

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

Yahoo Mail does not have a built-in option to block all emails from a domain (like all addresses ending in @example.com). You can only block individual email addresses. If you need to block many addresses from the same domain, you can block them one at a time, or use a filter to automatically delete emails from that domain.

Do blocked emails take up storage space in my account?

Blocked emails sit in your Spam folder and do count toward your storage limit while they are there. After 30 days, Yahoo deletes them automatically. If you want to free up space when ready, you can empty your Spam folder manually.

Can I block someone if I have not received an email from them yet?

You can block someone from your Contacts list even if you have never received an email from them. Go to Contacts, find their name, open their card, and select "Block contact". This prevents them from emailing you in the future, though their first message may still arrive before the block takes effect.
