How to Block Emails: A Comprehensive Guide

Spam emails can carry malware, act as phishing tools, and clutter your inbox. Automatic filters may be effective, but they're far from foolproof. According to Statista, in December 2021, over 45% of emails sent were spam. Blocking every rogue message aimed at your inbox is difficult. However, Clario's comprehensive security app can help detect malicious software, fraudulent emails, and phishing links before you end up in a scammer's trap.

Does a blocked sender know they are blocked?

No, they won’t know if you have blocked them. They won’t receive a notification you have filtered their messages from your inbox. Their emails simply go straight to spam if they try to send you anything.


Although there is no possible way for them to know if you have blocked them, they may suspect this — especially if you’re not replying to their messages.  

How to avoid getting unwanted emails

Here are some handy tips to prevent getting unwanted emails in the first place:

  • Read the fine print of apps and websites’ Terms and Conditions.

Maybe you’re checking on the auto-subscribe option of these tricky text boxes.

  • Only subscribe to trusted companies or websites.

If you do willingly want to get newsletters and other promotional messages, make sure these are from trustworthy brands. Reputable companies do not spam their subscribers and are less likely to be involved in a data breach.

  • Don’t engage with spammers.

Maybe you will be tempted to reply to these spammers to stop sending you messages. It would be better not to agitate them.

  • Use a disposable email.

Another technique tech-savvy individuals do is use another email address when they sign up to new websites. This is called a disposable email and unconnected to your personal accounts. When its security is compromised, you can simply abandon this email address and it doesn’t pose a risk to your other online accounts.

  • Don’t reveal your private email address on public domain websites or social media groups.

Bots, spammers, and scanners, are always on the lookout for email addresses readily available online. If you still want to post your email address on social media, you may want to limit who can see it to select contacts.

  • Get a cybersecurity software able to proactively send you alerts and protect all aspects of your digital life.  

The best way to protect yourself without having to worry is by downloading robust security software that does the job for you. With Clario, for example, you can detect malicious software, fraudulent emails, and phishing links before you end up in a scammer's trap.
