Remove and block spam from Gmail inbox 

In addition to blocking emails from unwanted senders, you can also reduce the amount of spam that gets into your inbox. Gmail has a handy spam filter for this task, and you can add unwanted senders to the list simply by opening a spam message and clicking the three dots icon as described above, but instead of Block, click Report spam. The procedure is similar for both a Mac and iPhone.

Alternatively, you can click on the Report spam icon in the upper left corner when you open the spam email. Look for the icon with an exclamation mark.

The reported message will go to the Spam folder and be completely deleted after 30 days.

You can do the same for multiple messages. To do this, check the boxes for messages that you consider spam and click on the icon with an exclamation mark. 

How to protect your Gmail from suspicious emails 

There may be something even more dangerous than spam in your Gmail inbox. We are talking about messages containing phishing links. The goal of phishing is to take over your logins, passwords, and other personal data. If you follow such a link, scammers can gain access to your accounts.

Google understands the danger of this type of fraud, so it takes serious measures to block such emails. Gmail algorithms detect phishing attacks using machine learning technologies. The company claims to be able to block 99.9% of malicious messages. However, this is still not a 100% guarantee. Therefore, if you see a suspicious message, you should report it. 

Here's how to report emails with phishing:

  1. Open Gmail on your computer. 

  2. Open the suspicious email and under no circumstances click on the links. 

  3. Click on the three vertical dots in the upper right corner and click Report phishing. 

  4. Confirm the action in the window that opens. And that's it.

Tip: Whether or not you've ever clicked on a link in a phishing email, it's a good idea to regularly scan your Mac for malware. That way, you can make sure it's not infected, and if the worst happens and you download something nasty, you can get rid of it quickly. CleanMyMac X is a handy app to keep on your Mac for all sorts of reasons, and it has a built-in malware removal module that detects all types of Mac-related threats.

How to improve email security: Strategies beyond blocking

In addition to blocking unwanted email, there are a few other steps you can take to increase your email security. Here's what you can do right now: 

  • Choose a secure email provider and client
    Some services are better at protecting your privacy than others and have more advanced tools to fight spam and unwanted emails. We already mentioned Spark Mail with its Gatekeeper feature. Another favorite of ours is Canary Mail that offers complete security and privacy for your emails. It has end-to-end encryption that makes your emails unreadable to third parties or prying eyes. In addition, the content of your emails, including attachments, is protected with Canary Mail's SecureSend feature.

  • Create strong passwords
    One of the easiest ways for hackers to access your email account is to guess or brute force your password. To prevent this from happening, use a strong and unique password that contains a mix of uppercase and lowercase letters, numbers, and special characters. You can follow our strong password tips to create one.

  • Turn on two-factor authentication (2FA)
    2FA adds an extra layer of security to your email account by requiring a second form of verification. It makes it much harder for someone to gain unauthorized access to your email, even if your password is exposed in a data breach.

  • Use a virtual private network (VPN) on public Wi-Fi
    VPN protects your connection by encrypting your data so that no one can sniff out your email address or other private information. ClearVPN has been proven to be a reliable security solution that reduces the security risks associated with public Wi-Fi networks. With ClearVPN, you're protected with military-grade encryption and stealth that prevents unauthorized intrusion and eavesdropping. 

To use ClearVPN on a public Wi-Fi hotspot, follow the steps below:

  1. Install and open ClearVPN (you can use it on both a Mac and iOS).
  2. Log in to the app.
  3. Choose the Smart connection mode and click the Connect me button.
  4. Once the VPN is connected, you can safely use public Wi-Fi.
