Email Open Tracking Accuracy and Privacy: What Users Should Know
A transparent explanation of image proxies, self-opens, metadata, and privacy-conscious product design.
Open counts are useful signals, not perfect evidence
Email clients may load images through a proxy, prefetch content, or block remote images. This can change when and how an event is recorded.
Sender self-opens need special handling
Opening a sent message can accidentally load the tracking image. Mail Audit uses compose-time blocking and recent-event compensation to reduce supported self-open false positives.
Store only what the product needs
Mail Audit keeps email body storage disabled by default. The service stores tracking metadata such as sender, recipient, subject, timestamps, status, and open counts so the dashboard can function.
