If you are looking for something like “read receipts” I dont think we have anything like that...+ we have no notification logs so it’s tough to say what was sent let alone what was opened...perhaps your IT team may've some suggestions?
Did some hack workarounds using like a tracking pixel added to the notification, not perfect, but better than nothing.
you may want to confirm or review your internal privacy policies before trying out a tracking pixel as it may cause some privacy concerns.
100% thanks @lrnlab
Also, would make sure to have some people who know what they are doing with them implement and help setup to avoid potential issues.
