Email Pixel Finder
Marketing emails contain invisible 1×1 images. When you open the email, your device silently loads the image — sending your IP address, browser, OS, and exact open time back to the sender.

🔒 No real data is collected. The x-ray panel shows what would be sent — it uses information your browser already provides to any website you visit.
How to use this tool
- 1 In Detective mode, click around the email below — you get hot/cold hints as you get closer to the hidden pixel.
- 2 When you find it, the x-ray panel opens and shows exactly what data it would send back to the sender.
- 3 Switch to Hacker mode to see the sender's perspective: click the blank email to plant your own pixel.
- 4 Watch fake "open" events roll in every few seconds — this is how real email analytics dashboards work.

How to block email tracking pixels
Email clients load remote images automatically — that is how pixels work. Blocking them is simple and breaks nothing important.
- Gmail: Go to Settings → General → Images → "Ask before displaying external images".
- Apple Mail (iOS 15+ / macOS Monterey+): Settings → Mail → Privacy Protection → "Protect Mail Activity" — this loads all images through Apple's proxy so senders cannot read your IP.
- Outlook: File → Options → Trust Center → Trust Center Settings → Automatic Download → "Don't download pictures automatically".
- Proton Mail / Tutanota: Images are blocked by default. The sender sees a generic Proton/Tutanota IP, not yours.
- Even with images loaded, a VPN changes your visible IP — senders still get your browser and OS, but cannot locate you geographically.
Can you tell if an email has a tracking pixel?
Not reliably, not by eye. A tracking pixel is a 1×1 transparent image — invisible in any email client. Even in the raw HTML source it is hard to spot because the URL is just another image request.
Most pixels are hosted at domains that look like CDN or analytics services (e.g. track.mailchimp.com, ep.sendgrid.net) — easy to miss in raw source.
Some senders encode the pixel inside a redirect chain, so the URL looks like a regular link but loads a 1×1 image at the end.
The pixel fires the moment the email is rendered — not when you click anything. Simply opening is enough.
Multiple pixels per email are common — one from the ESP (email service provider), one from the advertiser, one from a broker.
💡 Bottom line: The only reliable defence is preventing images from loading in the first place. Apple's Mail Privacy Protection and VPN usage are the two most effective tools for most people.
