Understanding Email Blocking in Yahoo Mail
Email blocking is a feature built into Yahoo Mail that lets you stop receiving messages from specific senders. When you block an email address, messages from that sender go directly to your spam folder automatically. Yahoo Mail does not notify the blocked sender that you have blocked them. The sender may not realize their emails are not reaching your inbox—they might think their message was delivered normally.

Blocking differs from other email management options. When you delete an email, you remove it from your inbox but the sender can still contact you in the future. When you mark something as spam, Yahoo learns that similar messages should be treated as spam, but future emails from that sender still arrive in your inbox initially. Blocking is more permanent and automatic—it stops emails before they clutter your inbox.
Yahoo Mail users can block both individual email addresses and entire domains. For example, you could block a single person's email address like "unwanted.person@example.com" or you could block all messages from an entire domain like "@example.com" to stop emails from everyone at that organization. The blocking feature works on all devices where you access Yahoo Mail, including computers, phones, and tablets, as long as you are signed into your Yahoo account.
According to Yahoo's support documentation, blocking is one of the most effective ways to manage unwanted correspondence. Unlike filters that require setup and rules, blocking works immediately and automatically. This makes it useful for dealing with harassment, marketing emails you no longer want, or contact from people you prefer not to hear from.
Takeaway: Blocking is a permanent, automatic feature that sends future emails from a sender straight to spam. It is different from deleting emails or marking them as spam, and it works across all devices where you use Yahoo Mail.
Step-by-Step Instructions for Blocking on Desktop
To block an email address using Yahoo Mail on a computer, start by opening Yahoo Mail in your web browser and signing into your account. Navigate to your inbox or find any message from the person or organization you want to block. You do not need to wait for a new message—you can block based on older emails already in your mailbox.

Open the email from the sender you wish to block. Look at the top of the email message. On the right side, you will see a series of icons and buttons. Click on the three dots (often called the "more options" menu) or look for a menu button. In Yahoo Mail's current interface, this is typically located near the subject line. A dropdown menu will appear with several options.
From the dropdown menu, select "Block [sender's email address]" or simply "Block." The exact wording may vary slightly depending on your Yahoo Mail version, but it will clearly indicate that you are blocking the sender. After you click this option, Yahoo Mail will ask you to confirm your choice. A popup window or confirmation message will appear asking if you are sure you want to block this sender. Click "Confirm" or "Block" to finalize the action.
Once confirmed, the blocking takes effect immediately. You will see a notification confirming that the address has been blocked. All future emails from this sender will automatically go to your spam folder. If you want to block multiple people, repeat this process for each address. There is no limit to how many addresses you can block in Yahoo Mail.
If you cannot find the block option in the dropdown menu, try right-clicking on the sender's name or email address within the message. A context menu may appear with additional options, including block. Different Yahoo Mail themes and updates may place this feature in slightly different locations, so exploring the message options thoroughly will help you find it.
Takeaway: Desktop blocking takes just three steps: open an email from the sender, click the menu button, select block, and confirm. After confirmation, all future emails from that address go directly to spam.
Blocking Email Addresses Using Mobile Devices
Yahoo Mail works on both iPhone and Android phones through the official Yahoo Mail app or through your phone's web browser. The blocking process on mobile devices is similar to desktop blocking but uses a mobile-friendly interface.

If you are using the Yahoo Mail app on your phone, open the app and find an email from the sender you want to block. Tap on the email to open it fully. At the top of the message, look for a menu icon—this typically appears as three horizontal lines (a hamburger menu) or three dots. Tap this icon to reveal more options. Scroll through the menu until you find "Block" or "Block sender." Tap this option and confirm when prompted.
If you are using a web browser on your phone to access Yahoo Mail, the process is the same as desktop—open an email, find the menu options, and select block. The main difference is that on smaller phone screens, some buttons may be in different positions or hidden behind menus to save space. You may need to scroll or expand sections to find all options.
Android users accessing Yahoo Mail through the app will see slightly different icons than iPhone users, but the general workflow remains the same. Both versions have a block option prominently displayed when you open an email. After blocking, you will receive a confirmation that the action was successful.
One advantage of blocking through the mobile app is that you can block senders while away from your computer. If you receive an unwanted email on your phone, you can block it immediately without waiting until you get to a desktop. The blocking syncs across all your devices, so once you block someone on your phone, they remain blocked when you check your email on a computer.
Takeaway: Mobile blocking works through either the Yahoo Mail app or a web browser. The steps are the same as desktop: open an email, access the menu, select block, and confirm. The block then applies across all your devices.
Blocking Entire Domains and Managing Multiple Senders
Beyond blocking individual email addresses, Yahoo Mail lets you block entire domains. A domain is the part of an email address after the "@" symbol. For example, if you wanted to block all emails from a company called "unwanted-company.com," you could block the entire domain instead of blocking each employee's individual email address one at a time.

To block a domain, use the same process as blocking an individual address. When you select "Block," Yahoo Mail may give you the choice to block just that specific email address or to block the entire domain. If given this choice, select the domain-blocking option. This prevents all future emails from anyone at that company or organization from reaching your inbox.
Blocking at the domain level is useful if you are getting emails from multiple people at the same organization and you do not want to hear from any of them. For instance, if you are getting recruitment emails from different staff members at the same company, blocking the domain stops all of them at once.
If you want to block multiple senders but do not want to block the entire domain, you will need to block each address individually. This is useful when you have problems with specific people but want to remain open to messages from others at the same company. For example, you might block one coworker's email address but continue receiving emails from your manager at the same organization.
Yahoo Mail does not publish a public list of blocked domains or addresses in your account settings. However, you can view your list of blocked senders in some versions of Yahoo Mail by going to Settings and looking for a "Blocked addresses" or "Blocked senders" section. The exact location depends on your account settings and Yahoo Mail version, but this information is available within your account preferences.
Takeaway: You can block entire domains to stop all emails from an organization at once, or block individual addresses to stop specific people. Blocking multiple addresses takes more time but gives you more control over who can reach you.
Viewing and Managing Your Blocked Senders List
After you block addresses, you may want to review your list of blocked senders or make changes. Yahoo Mail allows you to see who you have blocked and unblock addresses if you change your mind. To view your blocked senders, sign into Yahoo Mail and look for the Settings option. This is typically found in the top right corner of the screen, often represented by a gear icon.
