Blocking Emails on Gmail via Web
Directly From an Open Email
To block emails from a specific sender directly on Gmail’s web interface, start by opening a message from the sender you want to block. In the top-right corner of the open email, you’ll see three vertical dots next to the Reply button—this is the More menu. Click these three dots, then select Block “[sender’s name]” from the dropdown menu.

A confirmation dialog will appear; click Block to confirm. Once blocked, future emails from this sender will automatically be sent to your Spam folder, helping to keep your Gmail inbox clean from unwanted messages.
Through Gmail Settings (Filters and Blocked Addresses)
If you prefer to manage blocked email addresses more directly through settings, Gmail also lets you create filters to block certain senders. To do this, click on the gear icon to open Settings, then go to the Filters and Blocked Addresses tab. Here, you can add new filters by entering the sender’s email address in the From field and selecting actions like automatically deleting emails or sending them to Spam.

Block Directly from an Open Email on iOS and Android
Blocking emails on the Gmail mobile app is just as straightforward as doing it on the web. Start by opening the Gmail app on your iPhone, iPad, or Android device, then locate and open a message from the sender you want to block.
On Android devices, tap the three vertical dots next to the Reply button at the top right of the email. On iPhone, you’ll see three horizontal dots in the same location. From the menu that appears, select Block [sender’s name] to block that sender immediately.
Once you confirm the action, all future emails from this sender will be automatically sent to your Spam folder in Gmail, keeping your inbox free from unwanted messages.
If the email looks particularly suspicious or harmful, you have the option to Report spam instead of simply blocking. By selecting Report spam from the same menu, you help Gmail’s filters improve and prevent similar messages from reaching other users in the future. This approach is especially useful when dealing with phishing attempts or malicious content.

Manage Blocked Senders in Gmail Settings
For a more comprehensive view of all your blocked addresses in Gmail, it’s best to use the web interface. Open Gmail on your computer, click the gear icon, then choose See all settings and go to the Filters and Blocked Addresses tab.

From here, you can review all the email addresses you’ve blocked, unblock a sender if you’ve blocked them by mistake, or adjust filters that delete or redirect messages. This centralized location makes it easy to keep your blocked senders list up to date and fine-tune how Gmail handles unwanted emails.
What Happens When You Block Someone on Gmail?
Effect on Future Emails
Understanding what happens after you block an email address is essential for effectively managing your Gmail inbox. When you block a sender on Gmail, all future emails from that person are automatically redirected to your Spam folder.
This ensures that their messages won’t clutter your main inbox, keeping it organized. These emails are safely stored in the Spam folder, where you can review them if necessary. The blocking takes effect immediately, so any message from the sender after being blocked will bypass your primary inbox and go directly to Spam.
It’s important to note that blocking only impacts future emails. Any existing emails from that sender will remain in your inbox unless you manually delete them. If you want to manage spam safely, it’s worth understanding why you shouldn’t just delete spam emails and what you should do instead.
If you decide to unblock the sender, their future emails will return to your inbox as usual. However, if their messages still aren’t appearing after unblocking, Gmail’s filters might still be catching them for other reasons. In this case, you may need to adjust your filter settings or add them to your contacts to ensure proper delivery.
For users receiving frequent promotional emails or newsletters who prefer not to block the sender entirely, Gmail provides an alternative: the unsubscribe option. Instead of blocking the email address, you can unsubscribe from the sender’s list. This is often a more courteous way to stop receiving unwanted messages while maintaining the option to contact them in the future if needed.
Conclusion
Blocking emails on Gmail is an essential step to maintain a clutter-free inbox and protect yourself from unwanted messages. Whether you use the web interface or the Gmail mobile app, blocking a sender is quick and effective, sending future emails from that address directly to your Spam folder. Remember that blocking affects only future messages, so managing filters and blocked addresses can help fine-tune your email experience.
Take control today by applying these steps, and enjoy a cleaner, safer Gmail inbox without distractions from unwanted senders.
FAQ
How can I unblock a sender if I accidentally blocked them on Gmail?
To unblock a sender in Gmail, open Gmail on your computer, click the gear icon, then choose “See all settings.” Go to the “Filters and Blocked Addresses” tab, find the blocked sender, check the box next to their address, and click “Unblock selected addresses” to confirm.
What happens to emails from a blocked sender in Gmail?
Emails from a blocked sender in Gmail are automatically sent to your Spam folder. You won’t receive notifications for these messages, and they won’t appear in your inbox. Blocking doesn’t delete existing emails; only future emails are redirected to Spam.
Is it possible to block emails from a domain rather than just a single email address in Gmail?
Yes, you can block emails from an entire domain in Gmail by creating a filter. Search for from:@domain.com, open advanced search, create a filter, and choose “Delete it.” This will automatically delete all emails from that domain, not just a single address.
Can I block emails on Gmail without opening the unwanted message?
On desktop, you can block emails without opening them by copying the sender’s address from the message list (or using search), then creating a filter in Settings → Filters and Blocked Addresses to block or delete their messages. However, the Gmail mobile app requires opening emails first to block senders. If you want a safer option with more automation, third-party apps like Clean Email offer additional blocking and inbox-cleaning features.
