Email tracking guides for Gmail
Email tracking here means an optional 1×1 image in a message you send from Gmail on the web in Chrome. If that image is requested after Gmail’s Undo window, SentCue can show an activity signal next to the Sent row. Use it to decide when to follow up — not as proof that a named person read the mail.
Circles in Sent are short labels for that state: just sent, waiting for a signal, or activity detected. Proxies, scanners, and image blocking can still create a false cue or leave the circle empty. That is why these guides stay careful about wording.
