See when a pharmacy opens your Gmail emails, how many times, and which links they click. Works in Chrome, Edge or Brave on a computer.
Open the downloaded RxCommand-Gmail-Tracker.zip so it unzips into a folder. Keep that folder; don't delete it.
In Chrome, go to chrome://extensions and turn on Developer mode (top right).
Click Load unpacked and pick the RxCommand-Gmail-Tracker folder.
Open my.rxhealing.com and sign in. The extension links to your account by itself.
Open Gmail. New emails to pharmacies show a Tracked chip next to Send. Click it to turn tracking off for one email.
Emails to @rxhealing.com addresses are never tracked. Tracked emails include a small unsubscribe line, which the law requires. Your own views of your sent mail don't count as opens.
