Learn How to Block Email Addresses Across Mail Apps

Understanding Email Blocking Across Different Mail Platforms

Email blocking is a feature that most modern email services provide to help users manage unwanted messages. When you block an email address, messages from that sender typically go directly to your spam or trash folder, or they are rejected entirely before reaching your inbox. Different email platforms handle blocking in slightly different ways, so understanding how your specific service works is important before you start blocking addresses.

According to Statista's 2023 data, the average email user receives approximately 347 emails per day, with a significant portion being unwanted messages. This high volume makes blocking features valuable tools for maintaining inbox organization. Gmail, Outlook, Yahoo Mail, Apple Mail, and other services all offer blocking capabilities, though the steps and options vary.

When you block someone, they won't receive a notification that you've blocked them. Their emails simply won't appear in your inbox. However, it's important to know that blocking an address doesn't prevent the sender from knowing if you read their messages—it only stops their future emails from reaching you directly. Some services allow you to block entire domains, which can be useful if you're receiving spam from multiple addresses at the same organization.

The blocking process is different from unsubscribing from mailing lists. Unsubscribing is appropriate for marketing emails or newsletters where the sender included an unsubscribe option. Blocking is better suited for truly unwanted senders, harassing contacts, or persistent spam that regular filters don't catch. Most email services also maintain a block list where you can view, manage, and unblock addresses if needed.

Practical takeaway: Before blocking addresses, understand that blocking prevents messages from appearing in your inbox but doesn't notify the sender. If you're receiving unwanted marketing emails, check for an unsubscribe link first.

How to Block Email Addresses in Gmail

Gmail offers straightforward blocking options accessible through both desktop and mobile versions. On a desktop computer, open the email from the sender you want to block. Click the three-dot menu icon in the top right corner of the message. From the dropdown menu, select "Block [sender's email address]." Gmail will then ask you to confirm this action. Once confirmed, all future emails from that address will automatically go to your spam folder.

If you want to block an address without opening an email from them, you can use Gmail's settings. Go to Settings, then the Filters and Blocked Addresses tab. Click "Create a new filter" and enter the email address you want to block in the "From" field. In the next step, select the option to "Delete it" or "Skip the Inbox" (send to trash or spam). This method is useful when you know an address you want to block but don't have an active email from them.

On mobile devices using the Gmail app, open an email from the sender you wish to block. Tap the three-dot menu icon at the top of the message and select "Block [sender]." The process is nearly identical to the desktop version. Gmail's mobile app has become increasingly user-friendly, and blocking takes just a few taps.

Gmail stores your blocked addresses in a list you can manage. To view or modify your blocked senders, go to Settings, then Filters and Blocked Addresses. You'll see a complete list of every address you've blocked. If you want to unblock someone, simply click the "Unblock" button next to their address. This is useful if you blocked someone by mistake or if circumstances change and you want to receive their emails again.

Gmail also has a "Report spam" option that is slightly different from blocking. When you report an email as spam, you're helping Gmail's algorithm learn what spam looks like across all users. Blocking is more personal and direct, while reporting spam contributes to Gmail's security system. You can do both simultaneously—Gmail allows you to report spam and block the sender at the same time.

Practical takeaway: Gmail makes blocking accessible through the three-dot menu on any message. For preemptive blocking without receiving an email first, use the Filters and Blocked Addresses section in Settings to create custom filters.

Blocking Senders in Outlook and Microsoft 365

Outlook, whether accessed through Outlook.com or the Outlook desktop application, provides blocking features through a straightforward menu system. In the web version, open the email from the sender you want to block. Click the three-dot menu (More options) at the top of the message. Select "Block" from the available options. A dialog box will appear asking you to confirm that you want to block this sender and mark the email as junk. Outlook will then move the email to your junk folder and automatically send future messages from this address to junk.

In the Outlook desktop application, the process is similar. Right-click on the email from the sender you want to block. Select "Junk" and then "Block Sender." You'll see a confirmation message indicating that the sender has been added to your blocked list. Outlook will display a small notification confirming the action. From that point forward, emails from that address will go directly to your junk folder.

Microsoft 365 users have additional options through the advanced settings. You can manage your blocked senders list by going to Settings, then Mail, then Junk Email. This page shows you all addresses you've blocked and allows you to add new addresses manually. You can also manage safe senders here, which is the opposite of blocking—addresses on your safe senders list are more likely to reach your inbox even if they might otherwise be flagged as spam.

Outlook includes a useful feature where you can block an entire domain, not just individual email addresses. For example, if you're receiving spam from multiple addresses at company.com, you can block the entire domain. This is done through the Junk Email settings by adding domain names to your blocked list. This approach is more efficient than blocking dozens of individual addresses from the same organization.

One important distinction in Outlook is the difference between blocking and creating rules. While blocking automatically sends emails to junk, creating a rule gives you more control over what happens to messages. Rules can move emails to specific folders, delete them permanently, or mark them with a category. For persistent problems with certain senders, rules might offer more customized solutions than simple blocking.

Practical takeaway: Outlook makes blocking easy through the right-click menu or the three-dot options menu. For power users managing multiple unwanted senders, the Junk Email settings page allows bulk management and domain-level blocking.

Managing Blocked Addresses in Apple Mail and iPhone

Apple Mail, which comes built-in with Mac computers and iPhones, offers blocking capabilities that integrate with your device's operating system. On an iPhone or iPad, open the email from the sender you want to block. Tap the sender's name or email address at the top of the message. A contact card will appear. Scroll down and tap "Block this Contact." Apple will ask you to confirm your choice. Once confirmed, that sender will be blocked across your device's mail application.

If you're using Apple Mail on a Mac computer, the process is slightly different. Select the email from the sender you want to block. Go to the Mail menu at the top and select "Junk Mail." Then choose "Block All Mail from [Sender's Address]." Alternatively, you can right-click on an email and select the blocking option from the context menu. The Mac version provides immediate confirmation that the sender has been blocked.

One feature unique to Apple's ecosystem is that blocking syncs across your devices through iCloud. If you block someone on your iPhone, they are automatically blocked on your Mac, iPad, and any other Apple devices connected to your iCloud account. This unified approach means you don't have to block the same person multiple times across different devices. However, this also means unblocking on one device unblocks them on all devices.

Apple Mail's blocked list can be viewed in Settings on iPhone and iPad. Go to Settings, then Mail, then Blocked. Here you'll see all email addresses and contacts you've blocked. You can remove blocks by tapping "Edit" and then tapping the minus sign next to any blocked contact. On Mac, blocked contacts appear in your Contacts app with a blocked indicator, making them easy to identify and manage.

For users who use both Apple Mail and other email services like Gmail, it's important to understand that Apple Mail blocking only affects Apple Mail itself. If you check the same email account through Gmail or another service's interface, the blocking won't apply. You would need to set up separate blocks within each email service you use.
