How to Block Someone in Gmail (Web + Mobile, 2026)

Blocking someone in Gmail stops their emails from reaching your inbox. Future messages go straight to Spam and never trigger a notification.

This works for both personal contacts you no longer want to hear from and marketing senders that keep bypassing the unsubscribe.

Here is how to block someone in Gmail on desktop, Android, and iPhone in 2026.

Block someone in Gmail on desktop (web browser)

1. Open Gmail at mail.google.com.
2. Open any email from the sender you want to block.
3. Click the three vertical dots (More menu) in the top-right corner of the message.
4. Select Block [sender name] from the menu.
5. Confirm by clicking Block in the popup.

All future emails from this sender will land in your Spam folder automatically. Existing messages already in your inbox stay put unless you delete them.

Block someone in Gmail on Android

1. Open the Gmail app on your Android phone.
2. Tap the email from the sender you want to block.
3. Tap the three dots in the top-right corner.
4. Tap Block “sender name”.

The same block applies across all your devices signed into that Google account, including desktop and iOS.

Block someone in Gmail on iPhone or iPad

1. Open the Gmail app on your iPhone or iPad.
2. Tap an email from the person you want to block.
3. Tap the three dots at the top-right of the email header.
4. Tap Block sender.

iOS handles the block identically to Android. The block syncs to your Google account within seconds.

Unblock a sender in Gmail

If you change your mind, unblocking is easy:

1. Open Gmail on desktop and click the gear icon in the top-right.
2. Click See all settings.
3. Go to the Filters and Blocked Addresses tab.
4. Scroll to the “The following email addresses are blocked” section.
5. Find the sender in the list and click unblock.

Their future emails will resume landing in your regular inbox.

Block vs Report as Spam vs Unsubscribe

Gmail gives you three different tools for unwanted emails. Pick the right one:

• Block: use when you know the sender and want their emails routed to Spam. Personal use case.
• Report as Spam: use for unknown senders that look suspicious or phishing. Trains Google’s spam filter across all users.
• Unsubscribe: use for legitimate marketing emails you signed up for. Uses the email’s built-in unsubscribe link and removes you from their list at the source.

Create a Gmail filter to auto-delete blocked-adjacent emails

Blocking only works per exact email address. If a sender switches to a different address, you have to block that one too. A filter is more powerful because it can target any pattern.

1. Open Gmail on desktop. Click the search bar at the top.
2. Click the Show search options icon on the right side of the search bar.
3. Enter the sender email, subject keyword, or domain in the appropriate field.
4. Click Create filter at the bottom of the search box.
5. Choose “Delete it” or “Skip the Inbox” to auto-remove matching emails.
6. Click Create filter.

What happens when you block someone in Gmail

• Their emails still get sent to your address, but land in Spam instead of Inbox.
• Spam auto-deletes after 30 days, so you never see them again.
• You do NOT get a “delivery failed” bounce back to them. They do not know they were blocked.
• Blocking does NOT block them from seeing your Gmail-linked profile, calendar sharing, or Meet invites.
• If you need to block calendar invites too, remove them from Google Contacts and revoke calendar sharing separately.
