After you sign up, an Unsubscribe folder is created in your inbox. Drag in unwanted email and Unsubscriber will block emails from those senders from entering your inbox. Unsubscriber notifies the sender that you want to unsubscribe from their email list. Until that happens, new emails from that sender will be moved to your Unsubscribe folder. Unsubscriber works across major email providers like Gmail, Outlook, Yahoo! and more.
