Use targeted signatures and allow rules instead of disabling every image in every message.
No signature list can identify every tracker, especially a new or first-party custom pixel. Detection is a best-effort classification, not a guarantee of invisibility.
Blocking can reduce sender tracking but cannot undo information already exposed by clicking a link, replying, downloading remote content, or using a provider that prefetches it upstream.
Answers about setup, compatibility, privacy, and day-to-day use.
No. The design uses known signatures and scoped request rules, with allow rules intended to preserve ordinary images and privacy proxies.
Understand what is being requested before sharing the signal.
