Email OS gives your inbox a scriptable interface. It connects to your normal email account, then lets you handle daily email work with clear mailos commands.
Use it to send customer messages, search long threads, prepare safe drafts, forward known emails, manage campaigns, or let an AI agent help with inbox work while you keep control of what gets sent.
