How to Block and Report Spam Emails in Yahoo Mail

Spam emails clutter your inbox and can sometimes carry phishing links or malware. This guide shows you how to block unwanted senders and report spam directly from Yahoo Mail on the web, so your inbox stays cleaner and Yahoo’s filters get smarter. You’ll need a Yahoo Mail account and access to the web version (these steps also work on the mobile app with slight menu differences).

What You’ll Need

• A Yahoo Mail account (free or paid)
• Access to your inbox on a computer or mobile device
• The email you want to block or report (it can be open or selected in the list)

Step-by-Step

1. Open the email. Click on the spam email in your inbox to open it. If you haven’t opened it yet, you can also select the checkbox next to it in the message list.
2. Click the three-dot menu. In the open email, look for the three horizontal dots (⋯) in the top-right corner of the message pane, near the reply and forward icons. Click it to open a dropdown menu.
3. Select “Block Sender”. From the dropdown menu, click Block Sender. A confirmation dialog will appear.
4. Confirm the block. In the pop-up, click Block to confirm. Yahoo will block that email address and move the email to your Spam folder. You can also check the box to delete all future emails from this sender.
5. Report as spam (if not already). While the email is open, click the Spam button (the icon with an exclamation mark inside a stop sign) in the toolbar above the message. This reports the email to Yahoo’s spam filters and moves it to the Spam folder.
6. Report phishing (optional). If the email looks like it’s trying to steal your personal information (fake login pages, urgent requests for money), click the three-dot menu again and select Report Phishing. This sends the email to Yahoo’s security team and helps protect other users.
7. Unblock or manage blocked senders (if needed). To review or remove blocked addresses, go to Settings (gear icon) > More Settings > Security and Privacy > Blocked Senders. Here you can see the list and unblock any address you blocked by mistake.

Common Mistakes

• Not confirming the block. If you click “Block Sender” but don’t confirm in the pop-up, the block won’t take effect. Always click the final Block button.
• Blocking the wrong address. Some spam emails come from a different address than the “From” name. Check the actual email address (hover over the sender name) before blocking.
• Only blocking, not reporting. Blocking stops future emails from that sender, but reporting as spam also teaches Yahoo’s filters to catch similar emails from other senders. Do both for best results.
• Clicking links in spam emails. Even to “unsubscribe,” avoid clicking links in suspicious emails—they may lead to phishing sites. Use the block/report buttons instead.
• Forgetting to empty the Spam folder. Blocked and reported emails go to Spam, but they still count against your storage. Periodically empty the Spam folder (right-click > Delete) to free up space.

Tips

• Use filters for recurring spam. If you keep getting emails from a domain (like @example.com), create a filter: Settings > More Settings > Filters > Add new filter. Set the condition to “From” contains “example.com” and choose “Delete” as the action.
• Mark legitimate emails as “Not Spam”. If a real email lands in Spam, open it and click “Not Spam” to move it to your inbox and train the filter.
• Be cautious with “unsubscribe” links. Legitimate newsletters have an unsubscribe link, but spammers often use fake ones. If the email looks suspicious, block and report instead of clicking unsubscribe.
• Use a secondary email for sign-ups. To reduce spam, use a different email address for online purchases or forums, and keep your Yahoo address for important contacts.
• Check your blocked list regularly. You might accidentally block a legitimate sender. Review the list every few months and unblock if needed.

Troubleshooting

• Blocked sender still appears in inbox. This can happen if the email was already in your inbox before you blocked the sender. Move it to Spam manually, or delete it. The block only affects future emails.
• “Block Sender” option is grayed out. This usually means the email is already in your Spam folder or the sender is already blocked. Check your blocked list to confirm.
• Spam emails keep coming from different addresses. Blocking one address won’t stop a spammer who changes addresses. Use the “Report Phishing” option and create a filter for the domain name (if consistent).
• You can’t find the three-dot menu. On the mobile app, the menu is usually a horizontal line with three dots (⋯) at the top right of the open email. If you’re using a tablet, it might be under the reply arrow.
• Blocked list is empty but you still get spam. Make sure you’re looking at the correct account. If you have multiple Yahoo accounts, check the settings for the one receiving the spam.
• Emails from a blocked sender still appear in Spam. That’s normal—blocked emails are sent to Spam, not deleted. You can delete them manually or set up a filter to delete them automatically.

Frequently Asked Questions

Does blocking a sender in Yahoo Mail delete the email?

No, blocking a sender does not delete existing emails. It only prevents future emails from that sender from reaching your inbox—they go to the Spam folder. You can delete the current email manually.

Can the sender know I blocked them?

No, Yahoo does not notify the sender when you block them. They will not receive a message about the block, and their emails will simply not appear in your inbox.

What’s the difference between “Block Sender” and “Report Spam”?

Block Sender stops emails from that specific address and moves them to Spam. Report Spam also moves the email to Spam and sends a copy to Yahoo’s spam detection system, helping improve filters for everyone. Use both for maximum protection.

How do I unblock a sender I blocked by mistake?

Go to Settings (gear icon) > More Settings > Security and Privacy > Blocked Senders. Find the address and click the “Unblock” button next to it.

Will reporting spam get the sender banned?

Reporting spam helps Yahoo’s filters identify and block similar emails, but it doesn’t guarantee the sender’s account will be banned. If it’s a phishing attempt, Yahoo may take action against the sender.

Can I block a whole domain (e.g., @example.com) in Yahoo Mail?

Yahoo’s Block Sender only works with a full email address, not a domain. To block a domain, create a filter: Settings > More Settings > Filters > Add new filter, set “From” contains “example.com”, and choose “Delete” as the action.
