Can a message or notification be sent from our unit or our app, or is the sender always Aleris?

The sender is always Aleris, including the sender name on a notification, and never a unit, an app or a sub-brand.

One sender builds trust. Someone referred between three Aleris units should not have to work out whether they are dealing with one organisation or three, and a chat in the same product speaks as Aleris too, with no name or personality of its own.
