Unwanted emails or newsletters are still landing in your inbox no matter how many times you unsubscribe? Here’s how to block email addresses whether you use Gmail, Outlook, Yahoo or iPhone.

How to block an email address

Blocking emails can save you both time and hassle, especially for those who hate cluttered inboxes or spend a lot of time trying to find the most important emails during the workday.

When you block an email, it lets your email service provider know that you don’t want to receive messages from that sender. The next time this email address tries you send you something, it’ll land in your spam folder or straight to trash.

How to block an email address in Gmail

Gmail offers a few ways to block email addresses, depending on the type of email sent:

Removing yourself from mass emails

  • Gmail allows you to unsubscribe from promotional emails or newsletters when you open a message.
  • You will see a link that says “unsubscribe” or “change preferences” next to the sender’s name or at the bottom of the message.
  • Click link, confirm you want to unsubscribe.
  • If you don’t see a link, it means the sender didn’t give enough information to Gmail. Instead, you can click “report spam” at the top of the email if you’re on a desktop or by clicking on the ”More” section (the three vertical dots) on your mobile device.

Blocking an individual sender

  • Open the email message of the sender you want to block.
  • Right click the “more” button (three vertical dots).
  • Click on block [sender’s name].

Yahoo claims it works on improving and fine-tuning their spam and malicious email filtering technologies, so most spam is automatically blocked. However, you can train their filters as well as manually block email addresses:

  • Once logged into your account, right click on the email message from an address you want to block.
  • When the drop down menu appears, select “Block.”
  • You can choose to delete all existing emails as well as have Yahoo send all future emails from this address to go to the spam folder.
  • Another way to block an email address is to use the gear icon in the upper right corner to click on settings.
  • Select “blocked addresses” and enter the email address you want to block
