Email analyzer

Drop an .eml file, open one, or paste a whole message (headers and body). Everything is read in your browser: the message, its attachments and its links never leave your device.

Only the IP addresses, server names, domains (never the part before @), DKIM selectors and the link domains found in it are sent to our server to be looked up. Attachments are hashed here; nothing of them is sent. The message is held in this tab's memory only and dropped when you press Clear, analyze another or leave the page.
