How to block emails and stop unwanted senders
In today’s digital world, your inbox is a prime target for unwanted attention. Emails can become a major security gap if you're not careful, as various cyberthreats target them. So, it’s natural that email encryption alone isn’t enough. You need to control what kinds of emails reach your inbox.
One of the solutions is to block unwanted senders. By doing this, you not only ensure that threats don’t reach your account but also help maintain your overall privacy and security. That’s why in this article, I provide a quick guide on how to block emails and other useful tips.
Why block emails instead of just deleting them?
Spam, promotional emails, and other types of junk can reach your inbox. And too many emails, especially unwanted ones, in your inbox can be annoying or even stressful. Therefore, you should block them permanently instead of deleting.
I also believe that blocking emails is more proactive. Users who do this minimize security risks, as some types of unwanted emails can pose a serious threat. For example, phishing emails can steal your personal data. As stated in the Verizon Data Breach Investigations Report (DBIR), over 36% of breaches involve phishing, highlighting its significance.
Unwanted emails can sometimes lead to serious issues like harassment or doxxing (revealing private information online). That’s why blocking them is an important way to protect yourself. Moreover, according to Statista, malware attacks continue to rise, and many are delivered through malicious emails.
Blocking these senders not only reduces distractions but also strengthens your inbox’s security. Unlike simply deleting unwanted emails, blocking prevents future messages from ever reaching your primary inbox, giving you better control and peace of mind. I highly recommend integrating blocking as part of your broader email hygiene practices.

What happens when you block an email sender
After blocking a sender, incoming emails from them are typically diverted away from your primary inbox. On Gmail, they’re sent straight to the Spam folder. Outlook might reroute them to the Junk folder, and Apple Mail can move them to Trash. The sender isn’t notified when you block them, preserving your privacy.
However, blocking isn’t foolproof. Some persistent senders may bypass blocks by changing addresses. Even so, it’s a strong first step in managing spam and harassment. I always suggest combining blocking with creating custom rules or filters if you want to enhance your inbox security.
If you’re serious about stepping up your email defenses, consider services like ProtonMail. It offers powerful custom filters and advanced rules that let you fine-tune your inbox protection. These features help automatically sort or block suspicious messages, enhancing both your privacy and overall email security without extra hassle.
When blocking doesn’t work
Blocking an email address is helpful, but it’s not always a complete solution. Persistent spammers can bypass blocks by using different addresses or domains. This happens because basic email blocking usually matches only specific addresses.
When blocks fail, I recommend checking your spam and filter settings to strengthen your email defenses. Remove the sender from safe lists if applicable and create custom rules to catch variations.
For Gmail users, blocked emails generally go to Spam.
Outlook users might find blocked emails in the Trash. Regardless, doubling up blocking with smart filters gives you better results.
From my experience, ProtonMail is the best email service that allows you to create custom rules and block unwanted emails. However, if the problem continues, it’s best to reach out to your email provider’s support team for additional help.
FAQ
How can I block all emails from a domain?

Simply set up a rule using *@domain.com, and ProtonMail will automatically filter out unwanted senders, boosting your privacy and control.

Blocked emails – including their attachments – are delivered to Spam or Trash folders. They aren't automatically deleted unless specified by filters.
