Inbox is a tool that compiles all mail carriers into a single easy to use web service. It streamlines the email experience by giving added control over the collection & cataloguing process. The Inbox RESTful API allows one to access, modify, and filter incoming mail from popular providers like Gmail or Microsoft Exchange. Old protocols such as IMAP or MIME are thus not a problem using Inbox API. Mailbox API uses Threads and Tags to delineate and classify objects, and is enterprise compatible.
