Your inbox reports back
Most newsletters and many personal emails contain a tiny invisible image. When your mail app loads it, the sender learns that you opened the email, when, how often, and roughly where you are. Links are often wrapped so every click is recorded too. This tool looks inside a saved email without loading anything, and shows you what would have reported back.
How to save an email
- Gmail: open the email, ⋮ menu → Download message (.eml).
- Outlook on the web: ⋯ → Save as (.eml). Outlook for Windows: File → Save As.
- Apple Mail: File → Save As → Raw Message Source.
- Thunderbird: File → Save As → File (.eml).
How to stop it
Turn off automatic image loading in your mail app, or use one that blocks trackers. Apple Mail's "Protect Mail Activity" and Gmail's image proxy reduce what senders learn, but don't stop link tracking.
Questions
Does checking the email here trigger the tracking?
No. The email is read as text; no image or link is fetched, and our site blocks outside images anyway.
Is every tracker found?
No tool can promise that. It recognises common email services and typical pixel and redirect patterns, so treat the result as a strong hint, not proof.
