Google makes it easy to unsubscribe from mailing lists, but spam or phishing emails can still slip through. If you need to block an email address on Gmail, do the following:

  1. Open an email from the sender you would like to block.
  2. Click on the Dots icon in the upper right-hand corner.
  3. Select Block.

Blocking a particular email address through Gmail means you will no longer receive messages from that account in your inbox. It’s an all-or-nothing kind of thing. If you want to receive certain messages from that address but not others, you’ll have to put up with deleting a few emails every now and then.

Read on as we go into greater detail about how to block—and unblock—emails in Gmail, both from your phone and computer.

If you are on a computer

If you're on a computer, the process for blocking an email address on Gmail is pretty straightforward.

Step 1: Navigate to your Gmail inbox and open an email from the sender you would like to block.

Step 2: In the upper-right corner of the email — on the same horizontal plane as the sender’s name and address — is an icon made up of three vertically stacked dots. Select the Dots icon to open a drop-down menu.

Step 3: From this menu, select Block [sender’s name], which should appear near the middle of the list.

It’s that easy! Now any messages you get from that address will automatically be directed to your spam folder.

If you are on a smartphone

The process for blocking an email address on Gmail works the same on smartphones, although the interface looks a bit different.

Step 1: Open the email from the sender you want to block.

Step 2: In the upper-right corner of the message (not the app itself), there will be a button marked with three vertical dots (horizontal dots if you’re on iOS). This button is also located on the same horizontal plane as the name of the email’s sender. Select the Dots icon to open the drop-down menu.

Step 3: Choose Block [sender’s name]. You’ll now no longer receive messages from that email address.

When unsubscribing from a mailing list isn’t enough, blocking is an excellent way to help reduce the madness of unwanted messages in your inbox.

Unblock users

Did you mistakenly block an email address you didn't mean to block on Gmail? It's easy to reverse it. You will use the same drop-down menu you employed to block someone as you do to unblock them.

Step 1: Select the Unblock [sender’s name] option from either interface. Both interfaces also have a dark gray banner at the top of an email that came from a blocked sender. You can select the Unblock sender button on this banner to unblock that address, too.

Step 2: In the Gmail settings, you can find all of the addresses you’ve blocked by going to Filters and blocked addresses.

If you are getting emails from other Gmail accounts that contain threats or harassing content, you should know that such emails are a violation of Gmail’s Program Policies and can also be a violation of cyber harassment laws.

Not only should you block these email addresses but you should also file a police report for harassment and ask for further information about cybersecurity laws in your city.

AI models from Anthropic and OpenAI were caught breaking the rules again
A new report states AI agents from both companies took unauthorized actions during safety tests, from hacking a website to tricking real people online.

OpenAI and Anthropic have both had a rough few weeks on the AI safety front. OpenAI recently disclosed that its models broke out of a test environment and hacked into Hugging Face and four other organizations. The news prompted Anthropic to review its own testing, which revealed that Claude had also gained unauthorized access to three companies.

Now, the UK's AI Security Institute (AISI) has disclosed a new round of incidents (via Wired). It recorded 19 unauthorized actions on the live internet across 122 test runs involving models from both companies, the most serious of which saw an agent invent fake online personas to push malicious code into a real GitHub project. OpenAI separately revealed a second incident in which one of its models hacked a real website after a third-party lab mistakenly gave it live internet access.

Deepfake bosses are crashing video calls, and researchers are trying to expose them
Seeing your boss on video no longer proves they are real
Researchers at Fraunhofer SIT are fighting against deepfake meeting video calls

Entering into a meeting with your boss and several familiar coworkers inside a video conference is the next area vulnerable to cybercrimes, and it's all because of deepfake technology. Researchers at the Fraunhofer Institute for Secure Information Technology SIT are working on a real-time warning system designed to identify attempted fraud during corporate video conferences.

The report states that criminals are increasingly targeting video meetings for identity theft and financial scams, taking advantage of the trust people place in familiar faces and voices. The intention is to flag suspicious activity while the meeting is still taking place. This gives an employee a chance to stop before following an expensive instruction from an AI-generated executive.
