A newsletter from which you just don't seem to be able to unsubscribe and the odd radio station that keeps emailing you in a language no online translator recognizes—these are delivery annoyances you know to ignore and delete. However, the reasons to block senders are many, and you can clean up your Inbox by blocking them instead of spending time deleting their emails.

In Zoho Mail, there are two ways to block senders. You can set up a filter from an existing message or place the sender's address or their entire domain on Zoho Mail's list of blocked senders.
