What is Inbox Zero?
Inbox Zero is an open-source AI assistant for Gmail and Outlook that labels, archives and drafts replies based on rules you write in plain English. It also includes a bulk unsubscriber and cold email blocker.
You describe how emails should be handled, such as 'archive receipts and label them', and the assistant applies the rules automatically. You can use the hosted version or self-host the code from GitHub, and analytics show who emails you most.
