Email Header Analyzer
Paste an email header, get the route, authentication results and delays. Everything runs locally in your browser, nothing is uploaded.
About this tool
Email Header Analyzer: free, fast, browser-only. Nothing you type leaves this page.
Why free, and what happens next
Tools like this one are how this desk stays findable: useful first, commercial when you are ready. When a tool surfaces a problem you would rather have fixed than diagnosed, start a project or run the cost calculator first. Everything runs client-side: your data never leaves this page.
