Tracking Report

Open the MailTrackerBlocker app or tap the 🧩 jigsaw puzzle icon in Mail that appears over the message pane header (note: the 🧩 jigsaw puzzle icon is hidden if the selected e-mail has an attachment). The Tracking Report shows a rolling 30-day overview of e-mails grouped by tracker along with some frequency statistics.

FAQ

Does this work with Mail Privacy Protection?

Yes, even in network environments (e.g. VPN) where Mail Privacy Protection doesn't work, MailTrackerBlocker will still block and identify trackers if you choose to "Load Remote Content".

Note: Mail Privacy Protection's proxy will still fetch the tracker image, triggering the tracker after an unknown period of time. In the period of time before this happens, if you open your email without MailTrackerBlocker, the proxy will fetch the tracking image and trigger the tracker at that moment still letting the tracker know your exact opening time.
