Every email begins with one server introducing itself to another, waiting for permission to speak. Follow the journey from Send to Inbox.
An email's journey from Send to Inbox is a story of trust negotiations—servers proving identity, encrypting secrets, and passing responsibility hand to hand across the Internet.
Every email writes the story of its own journey. Headers are that autobiography—documenting where a message came from, every server it touched, and whether it can prove it is who it claims to be.
Your email lives somewhere—either on your device or on someone else's server. That choice shapes everything about how you work with it.
