I have been using my email for a long time, and have applied for many online services, so I must often receive advertising letters. Unless you are a diligent person, most people are like me. They ignore advertising letters when they see them, and are too lazy to delete them manually. Over time, the mailbox becomes full of these advertising letters. Unsubscriber by Polymail is a very useful little tool that scans all subscribed letters in the mailbox, allowing us to manage and cancel them easily and quickly without having to search for them one by one.
