Block Annoying Addresses in Gmail: Step-by-Step

This guide shows you how to stop unwanted emails from specific senders from cluttering your Gmail inbox. By blocking an address, future messages from that sender go straight to your Spam folder, and you can also remove all existing emails from them in one go. All you need is a Gmail account and access to the web version or the mobile app.

What You’ll Need

• A Gmail account (free or Google Workspace)
• Access to Gmail on a computer browser or the Gmail mobile app
• The email address of the sender you want to block (you can find it in any of their emails)

Step-by-Step

1. Open Gmail – Go to mail.google.com in your browser and sign in if you aren’t already. On mobile, open the Gmail app.
2. Open an email from the sender – Click or tap any email message from the address you want to block. It doesn’t matter if the email is in your Inbox, Spam, or a label folder.
3. Click the three-dot menu – In the top-right corner of the open email (next to the Reply arrow), click the vertical three-dot icon. On mobile, it’s in the top-right of the message view.
4. Select “Block [sender name]” – From the dropdown menu, choose the option that says Block followed by the sender’s name or address. A confirmation pop-up will appear.
5. Confirm the block – In the pop-up, Gmail asks if you want to block the sender and also delete all existing emails from them. Check the box if you want to remove their past messages (recommended for a clean inbox), then click Block.
6. Verify the block – After confirming, you’ll see a small banner at the top of the screen saying “[Sender] is blocked.” From now on, their emails will go to your Spam folder automatically.
7. Unblock if needed – To undo a block, go to Settings (gear icon) → See all settings → Filters and Blocked Addresses tab. Find the address under “Blocked addresses” and click Unblock.

Common Mistakes

• Blocking the wrong address – Senders can use multiple addresses or display names. Make sure you’re blocking the exact email address, not just the name shown.
• Expecting emails to disappear – Blocking alone does not delete existing emails. You must check the “Also delete existing emails” box during the block process, or manually delete them afterward.
• Blocking from the wrong folder – The three-dot menu is available in any folder, but if you’re in Spam, make sure you’re opening the actual email, not just hovering over it.
• Forgetting that blocked emails still occupy storage – Even though they go to Spam, they count toward your storage until permanently deleted from Spam (which happens after 30 days).
• Blocking a mailing list instead of the sender – If you’re getting emails from a newsletter, you might want to unsubscribe instead of blocking, as the list may send from many addresses.

Tips

• Use filters for more control – If you want to block a domain (e.g., @spam.com) or only certain types of emails, create a filter: click the gear icon → See all settings → Filters and Blocked Addresses → Create a new filter. Enter criteria (like domain) and choose “Delete it” or “Skip the Inbox.”
• Block from the mobile app – The steps are the same: open the email, tap the three-dot menu, and select “Block.”
• Report spam for unknown senders – If you get an unsolicited email from a random address, use the “Report spam” button (the exclamation mark icon) instead of blocking. This helps Gmail improve its spam detection for everyone.
• Unsubscribe from legitimate marketing – For newsletters you signed up for, scroll to the bottom of the email and click “Unsubscribe.” This is more polite and effective than blocking, and it frees you from their emails without filling Spam.
• Check your Spam folder occasionally – Blocked emails land in Spam, so if you’re waiting for an important email from a blocked sender, you’ll need to check Spam or unblock them.

Troubleshooting

• Block option is grayed out or missing – This can happen if you’re viewing a message in a shared or delegated mailbox. Make sure you’re in your own Gmail account. Also, if you’re using a work or school Google Workspace account, your administrator may have disabled the block feature.
• Emails still appearing in Inbox after blocking – Wait a few minutes; Gmail may take a short time to apply the block. If they continue, the sender might be using a different address. Check the full email header (click the three-dot menu → Show original) to see the actual “From” address.
• Blocked emails are not in Spam – By default, blocked emails go to Spam. If you don’t see them, check your Spam folder settings: in Gmail settings, under “Filters and Blocked Addresses,” ensure the block is listed. Also, if you have a filter that deletes or archives messages, it might override the block.
• You accidentally blocked someone you need – Go to Settings → Filters and Blocked Addresses → find the address under “Blocked addresses” → click Unblock. Then send them an email to re-establish contact.
• Blocking a domain doesn’t work – The block feature only blocks exact email addresses. To block an entire domain, create a filter as described in the Tips section.

Frequently Asked Questions

1. What happens to emails from a blocked sender?
They are automatically sent to your Spam folder. You won’t get notifications, and they won’t appear in your Inbox.

2. Can the sender know they are blocked?
No. Gmail does not notify the sender. Their emails will still appear as “sent” on their end, but you won’t see them in your Inbox.

3. Does blocking an address delete all previous emails from them?
Only if you check the “Also delete existing emails” box when confirming the block. Otherwise, you can manually delete them.

4. How do I unblock someone?
Go to Gmail settings (gear icon) → See all settings → Filters and Blocked Addresses tab. Under “Blocked addresses,” click Unblock next to the sender’s address.

5. Can I block a sender on the Gmail mobile app?
Yes. Open the email, tap the three-dot menu (top-right), and select Block. The process is the same as on desktop.

6. Is blocking the same as reporting spam?
No. Blocking only affects emails from that specific address. Reporting spam also trains Gmail’s filter to catch similar emails from other addresses. You can do both if needed.
