💡 In Plain English: What is an Email Header?
When an email travels across the internet, every mail server it passes through leaves a digital passport stamp (header). This tool acts like an X-ray scanner: it traces the message's journey across the world, checks if the sender is fake or spoofed (DMARC), and pinpoints where delivery delays occurred.
Headers are processed exclusively inside your browser DOM. No data is sent over the network.
