How To Block An Email Address In 2023

If you’re tired of all the spam that reaches your inbox, here’s how to block an email address from specific senders if you use Gmail, Yahoo, Outlook, or another email provider. You’ll also find out how Clean Email, a modern inbox cleaner, can help you manage your mailbox.

How to Block Emails on Gmail

Gmail does a good job of sorting your incoming mail and placing them in the right places, including moving spam messages to the Spam folder. Still, some spam and unwanted emails can get through and clutter your Inbox.

Probably the easiest way to stop seeing unwanted emails is to block a message so that Gmail automatically delivers messages from the sender’s address to the Spam folder. We have a quick video tutorial that shows how to block unwanted emails so that you won’t see them in your Gmail inbox:

To block someone on Gmail using the Gmail web app and to block emails on Android phones using the Gmail mobile app, follow these steps:
