64. Do all the users assigned to the Sender ID get the Incoming message email or is the last person who sent them the only recipient?

All incoming notifications in the managed package can be defined under Converse Settings. You can configure the settings to allow email alerts for incoming notification to be sent to the last sender or the user to whom the Sender ID is assigned. This is the default setting the app offers.

In addition to this, we can also customize the configurations for alert notifications on Incoming messages based on individual requirement.
