We have noticed that the same
tracking_hash value has been assigned to multiple contacts / leads. This results to an error where a recipients clicks the tracking URL like below:
and a different person is unsubscribed because the tracking_hash value is the same and it just picks the first instance of that
The worst scenario is the same tracking_hash value being assigned to 5 leads / contacts.
Please advise if anyone has seen this behaviour and if we can fix it somehow ?
