You might be tempted to move email from the Spam folder to your new Unsubscribe folder — in a word, don’t. Email in your Spam folder is exactly where it needs to be. The Unsubscribe folder is for email that has reached your inbox that you no longer want to receive. Anytime you move an email out of your Spam folder, your email service thinks it made a mistake and you do want to receive those emails, which is definitely not your intention.
So, leave spam where it is and only use the Unsubscribe folder for emails you find in your inbox.
