Open signals and proof of reading
What an open request records, how HawkOpen classifies it and why it is not proof of reading.
These comparisons describe HawkOpen only. They do not assess other products or establish production readiness.
Recorded request
Once your company’s owner or administrator has switched tracking on, HawkOpen adds a unique 1×1 image URL for each recipient whose consent to tracking is recorded; others get an ordinary email. When that URL is requested, HawkOpen records and classifies a technical open signal. It may come from a person, privacy proxy, scanner or unknown client; it is not proof of reading.
HawkOpen classification
Each tracking-image fetch is checked against named rules for Apple Mail Privacy Protection, mail-provider proxies, security scanners and link previews, and shown with its rule codes.
Evidence and availability limits
A note on accuracy: HawkOpen records tracking-pixel and tracked-link requests as technical signals. Apple Mail Privacy Protection, image proxies, caching, bots and security scanners can cause false or ambiguous events.
