Spam. Annoying newsletters. That one contact who just won’t quit. Blocking emails in Gmail is one of the easiest ways to take back control of your inbox—and yes, you can do it from any device.

In this quick guide, I’ll walk you through how to block and unblock emails in Gmail on iPhone, Android, and the web browser. Whether you want to cut off a spammer or bring back someone you blocked by mistake, it’s all simple.

🔒 How to Block Emails in Gmail

On iPhone (Gmail App)

1. Open the Gmail app.
2. Find and open the email from the sender you want to block.

4. Tap “Block [Sender Name]”.

That’s it. Future emails from them will go straight to your Spam folder.

On Android (Gmail App)

Same steps as iPhone:

1. Open the Gmail app and go to the email.
2. Tap the three dots (top right of the message).
3. Select “Block [Sender Name]”.

Gmail will auto-filter emails from that sender to Spam.

On the Web (Desktop or Laptop)

1. Open Gmail.com and log in.
2. Open an email from the sender.
3. Click the three dots (top right of the email next to the “Reply” arrow).
4. Choose “Block [Sender Name]”.

Again, Gmail will move future emails from this sender to Spam.
