The fastest way to block someone in Gmail

Open the email from the person you want to block. Click the three dots (more options) in the top right corner of the email. Select Block "[sender's name]" from the menu. Gmail will move that sender's future emails to spam automatically.

That is the complete process. Once blocked, you will not see emails from that address in your inbox, and Gmail will not notify you when they send something. The sender does not know they have been blocked — their emails straightforward disappear into your spam folder.

If you want to unblock someone later, go to Settings, click the Filters and Blocked Addresses tab, find the blocked sender, and click Unblock next to their name.

Key Takeaways

  • Open any email from the sender, click the three dots, and select Block to send all their future messages to spam automatically.
  • Blocked senders cannot tell they have been blocked, and their emails will not trigger notifications in your inbox.
  • You can unblock a sender at any time through Settings by going to Filters and Blocked Addresses.
  • Blocking only affects new emails — it does not delete or hide messages you have already received from that person.
  • If someone uses multiple email addresses, you will need to block each address separately.

What happens when you block an email address

When you block a sender, Gmail routes their emails directly to your spam folder. You will not see a notification, and the message will not appear in your inbox. If you check your spam folder, you can still read blocked messages — blocking does not delete them, it just hides them from your main view.

The blocked sender will not receive a bounce-back message or any indication that you have blocked them. From their perspective, their email was sent normally. They might notice you are not responding, but they will not know it is because of a block.

Blocking email from a different device or Gmail version

If you use Gmail on your phone, the process is slightly different. Open the email, tap the three dots at the top, and select Block sender. The block applies to your entire Gmail account, not just your phone — so if you block someone on mobile, they are blocked on your computer too.

If you use Gmail through Outlook, Apple Mail, or another email client that connects to your Gmail account, blocking through those apps may not work the same way. To be certain the block takes effect, use the Gmail website or the official Gmail app on your phone.

When blocking does not work the way you expect

If you keep receiving emails from someone you blocked, they may be using a different email address. Blocking sender@example.com does not block sender2@example.com or newsender@example.com. You will need to block each address separately.

Some senders use email forwarding services or temporary email addresses that change with each message. In those cases, blocking individual addresses becomes impractical. Instead, consider using Gmail filters to automatically delete or archive emails containing certain keywords or phrases.

Using filters as an alternative to blocking

If you want more control than blocking offers, create a filter. Go to Settings, click Filters and Blocked Addresses, then click Create a new filter. Enter the sender's address or a keyword from their emails. Choose what Gmail should do with matching emails — delete them, send them to spam, or archive them automatically.

Filters are useful when someone uses multiple addresses or when you want to catch emails with specific words in the subject line. You can also create a filter that applies a label, so emails matching your criteria go into a folder you can review later without cluttering your inbox.

Blocking group emails and mailing lists

If you receive emails from a mailing list or group address, blocking works the same way — click the three dots and select Block. However, if the list is managed by your workplace or a service you signed up for, blocking may not be the best solution. Consider unsubscribing instead, which usually involves a link at the bottom of the email.

If you cannot find an unsubscribe link, check your email settings to see if you can mute the conversation instead. Muting stops notifications but keeps the emails in your inbox if you need to reference them later.

Recovering blocked emails if you change your mind

Blocking does not delete messages you have already received. If you unblock a sender later, you can still find their old emails in your spam folder. Go to Spam, search for their name or address, and move the message back to your inbox if you need it.

If you unblock someone, their future emails will go to your inbox again instead of spam. You can block them again at any time without losing access to previous conversations.

Frequently Asked Questions

Can I block an email address without opening an email from them?

No — Gmail requires you to open an email from that sender first. If you have not received a message from them yet, you cannot block them proactively. You can create a filter instead to handle emails from that address automatically once they arrive.

Will the person I block know I blocked them?

No. They will not receive a notification, bounce-back message, or any technical indication that you blocked them. They may notice you are not responding to their emails, but Gmail does not tell them why.

What is the difference between blocking and unsubscribing?

Blocking sends all emails from that address to spam. Unsubscribing removes you from a mailing list — it works only if the sender is a legitimate business or organization that honors unsubscribe requests. For unwanted personal emails, blocking is more reliable.

Can I block someone if they use a fake name or spoofed address?

You can block the email address that appears in your inbox, but if someone is spoofing addresses (making emails look like they come from someone else), blocking may not stop them. They can straightforward use a different fake address. Report these emails as spam or phishing instead.

Does blocking someone in Gmail block them on other Google services?

No. Blocking in Gmail only affects email. It does not block them from contacting you through Google Chat, Google Meet, or other Google products. You would need to block them separately in those services if needed.
