How to Block Emails on Gmail

To learn how to block someone on Gmail and move all future emails you receive from the address to the Spam folder:

  1. Open a message from the sender you would like to stop.
  2. Click on the little arrow next to the reply button and select the “Block [sender’s name]” option.

  1. A confirmation message should appear, telling you that you’ve successfully blocked the sender.

Should you ever decide to unblock the sender, simply open any message you’ve received from it, click on the little arrow next to the reply button and select the “Unblock [sender’s name]” option. If you can’t find any message from the sender, click on the Settings gear icon and select the Settings option. Go to Filters and Blocked Addresses and select the address you would like to unblock.

The problem with spammers is that they often keep randomly generating new email addresses, forcing users to block each new spam message individually. It probably won’t surprise you much to learn that many people simply give up after a while and live with an inbox full of spam emails.

The good news is that Gmail makes it very easy to create rules to block an entire domain name in a single step:

  1. Click on the triangle located on the right side of the search bar.
Click on the triangle
  1. Type the desired email address under From. Keep in mind that you don’t have to type the entire email address and can enter only the domain name.

  1. Click on the “Create filter with this search” option, which is located on the bottom-right corner and can be hard to see.
  2. Check the “Delete it” option to automatically delete all emails from the desired address.

  1. Click Create filter.

How to Block Email on Yahoo

How to Block an Email Address in ProtonMail

Even though one of the most secure providers ProtonMail uses a smart spam detection system to automatically block spam email messages, sometimes junk emails get through anyway. When that happens, the best defense is to block the sender using ProtonMail’s filters.

  1. Go to your ProtonMail inbox and click on the Settings option located in the top-right corner.
Proton settings
  1. From the menu on the left, select the option entitled Filters. There, you can mark specific email addresses as spam.

How to Block an Email Address in iCloud Mail

To set up rules to block email addresses in iCloud Mail:

  1. Log in to your iCloud Mail inbox.
  2. Click the settings gear icon in the sidebar and choose Rules.
  3. Click Add a Rule and specify the filtering conditions.

How to Block an Email Address in Yandex Mail

Yandex Mail does a lot to stop unsolicited messages from entering your inbox. It uses a sophisticated anti-spam service that leverages machine learning technology to learn from user-submitted spam complaints in order to accurately recognize spam emails. When it does determine that a message is likely spam, it puts it in the Spam folder, where it stays for 10 days before it’s automatically deleted.

In addition to relying solely on the Yandex Mail anti-spam service, users can also stop senders directly by adding them to the blacklist. To block an email address in Yandex Mail:

  1. Go to your Yandex Mail inbox and click the settings gear icon in the upper-right corner.
  2. Select the Message filters option.
  3. Scroll down to the Blacklist section in the lower-left corner of the screen.
  4. Enter the address and click Add.

Yandex Mail imposes a couple of blacklist restrictions that you should keep in mind when blocking email addresses. You can only block full email address like example@domain.com. All partial mail addresses (@domain.com) are simply ignored. When you add an email address to your blacklist, Yandex Mail doesn’t delete older messages sent to you from the email address. To do that, you need an inbox organizer like Clean Email (more about it in the last chapter of this article). Finally, you can’t block more than 1,000 email addresses.
