Users will receive this email whenever they have a high consumption day that deviates from similar day usage profile. These similar day profiles will update over time, bill cycle over bill cycle, so if their consumption profile changes due to lifestyle changes, they will eventually stop receiving this email once their usage profile pattern is re-established by the algorithm.
A user can also go to their preferences page on the web portal directly or by clicking on a call-to-action button in email and unsubscribe from there.
