The Subscription Auditing module tracks the date and time changes made to the recipient's email address, activation status, and their subscription preferences.
It is useful for organisations who need to know who, when, where and how changes were made. If you are worried about the Spam Act, then this is the module you need to protect yourself against false allegations.
Organisations where delivery of the right information to the right people is a must, such as financial institutions, would also find it extremely valuable.
