The fastest way to block an email sender

Open the email you want to block. Look for the three vertical dots (the menu icon) in the top right corner of the email. Click it, then select Block "[sender name]" from the dropdown menu. Gmail will when ready send future emails from that sender to your spam folder.

That is the complete process. The sender will not know they are blocked, and you will not receive notifications from them. If you change your mind later, you can unblock them by going to Settings and finding the blocked addresses list.

This method works for individual email addresses. If you are getting unwanted mail from a business or service you signed up for, the unsubscribe link at the bottom of their email is usually faster than blocking — it removes you from their list entirely rather than just hiding future messages.

Key Takeaways

  • Click the three-dot menu on any email and select Block to send that sender's future messages straight to spam.
  • Blocking hides emails but does not notify the sender or stop them from sending — unsubscribe is better for mailing lists you no longer want.
  • You can view and manage your blocked senders list in Gmail Settings under Filters and Blocked Addresses.
  • Gmail's spam filter learns from emails you mark as spam, so reporting unwanted mail trains the system to catch similar messages automatically.
  • Creating filters lets you automatically delete, archive, or label emails from specific addresses or containing certain words before they reach your inbox.

Blocking multiple senders at once through Settings

If you have several addresses you want to block, or if you want to see all your blocked senders in one place, go to Gmail Settings. Click the gear icon in the top right, then select See all settings. Navigate to the Filters and Blocked Addresses tab.

Scroll to the bottom of the page. You will see a section labeled Blocked addresses that lists everyone you have already blocked. To add a new address, type it into the text field and click Block. You can add multiple addresses this way without opening individual emails.

This approach is useful if someone is emailing you from a different address than before, or if you want to block an address before you receive anything from them. The blocked address will not appear in your inbox, spam folder, or anywhere else in Gmail.

Using filters to automatically handle unwanted emails

Filters are more powerful than blocking because they let you decide what happens to emails before they arrive. Go to Settings, then Filters and Blocked Addresses, and click Create a new filter at the bottom.

In the search box, type the sender's email address, a word that appears in unwanted emails, or any other detail that identifies the messages you want to catch. Click Create filter. Now you choose what Gmail does with matching emails: delete them, send them to spam, archive them automatically, or explore a label so you can find them later if needed.

Filters are especially useful for emails that come from many different addresses but share a common word or phrase. For example, you could create a filter that automatically deletes any email containing "limited time offer" in the subject line, or one that archives all messages from a particular domain.

Teaching Gmail's spam filter to recognize unwanted mail

Gmail learns from your behavior. Every time you click the Report spam button on an email, you are training Gmail's filter to recognize similar messages in the future. Open an unwanted email, click the three-dot menu, and select Report spam.

Over time, Gmail gets better at catching emails like that one before they reach your inbox. This is different from blocking — blocking only affects that one sender, but reporting spam helps Gmail protect you and other users from similar unwanted mail. If you receive many emails with the same subject line or from addresses that look similar, reporting them teaches the system to catch the pattern.

You can also mark emails as spam by selecting the checkbox next to them in your inbox list, then clicking the spam icon (it looks like an exclamation point in a triangle) at the top of the list.

Unsubscribing from mailing lists and newsletters

Most legitimate businesses and newsletters include an unsubscribe link at the very bottom of their email. This is usually the fastest way to stop receiving their messages. Click the unsubscribe link, and the sender removes your address from their list — you will not receive future emails from them.

Unsubscribe is different from blocking. When you unsubscribe, you are telling the sender to remove you. When you block, you are telling Gmail to hide their messages. For services you signed up for intentionally but no longer want, unsubscribe is the cleaner option because it removes you from their system entirely.

If an email does not have an unsubscribe link, or if clicking it does not work, then blocking or reporting it as spam is the right move. Legitimate senders are required to include a working unsubscribe option, so missing one is often a sign the email is unwanted anyway.

Blocking emails with attachments or images you do not trust

Gmail scans attachments and images for viruses and malware, but you can add extra protection by blocking senders whose attachments concern you. Open the email, click the three-dot menu, and select Block "[sender name]". This prevents them from sending you anything else, including files.

If you receive an email with a suspicious attachment but are not sure whether to block the sender, you can also just delete the email without opening the attachment. Gmail will not read or execute the file unless you click on it. Hover over the attachment to see a preview and decide whether it looks legitimate before you open it.

For extra caution, you can create a filter that automatically deletes all emails from a sender that contain attachments. Go to Filters and Blocked Addresses, create a new filter with the sender's address, and in the filter options select Delete it. This catches emails from that sender even if they use a slightly different address.

What happens after you block someone

Once you block a sender, their emails go directly to your spam folder. You will not see notifications, and the emails will not clutter your inbox. If you want to see what you blocked, go to your spam folder — blocked emails sit there for 30 days before Gmail deletes them automatically.

The sender does not receive a message saying they are blocked. They may not even know their emails are not reaching you. If they contact you through another method asking why you are not responding, you can explain that their emails are going to spam, or you can straightforward not respond.

If you decide later that you want to receive emails from someone you blocked, go to Settings, find the Filters and Blocked Addresses tab, locate their address in the blocked list, and click the delete icon next to it. They will be unblocked when ready, and their future emails will arrive normally in your inbox.

Frequently Asked Questions

Can I block an email address that has not sent me anything yet?

Yes. Go to Settings, then Filters and Blocked Addresses, and type the address into the blocked addresses field. This prevents emails from that address from ever reaching your inbox. It is useful if you know you do not want to hear from someone before they contact you.

Will the person I blocked know that I blocked them?

No. Gmail does not notify senders when they are blocked. Their emails straightforward go to spam, and they have no way of knowing unless you tell them. They may notice you are not responding, but they will not receive a message from Gmail saying they are blocked.

What is the difference between blocking and reporting spam?

Blocking stops emails from one specific sender from reaching your inbox. Reporting spam does the same thing but also trains Gmail's filter to catch similar emails from other senders in the future. Use report spam for unwanted mail you want to help Gmail recognize, and blocking for individual senders you straightforward want to ignore.

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

Not directly through the block button, but you can create a filter that catches all emails from a domain. Go to Filters and Blocked Addresses, create a new filter, and type the domain (for example, @unwanteddomain.com) in the search field. Then set the filter to delete or spam all matching emails.

If I block someone, will they still be able to see my emails if I sent them something before?

Blocking only affects emails coming to you from them. It does not change anything about emails you already sent them, and it does not prevent them from seeing your address in their inbox. Blocking is one-way — it only stops their incoming mail.
