Greetings!
Regarding CC'd notifications of agreements, the default application behavior is to notify CC'd parties when the agreement is first created, and when it is finalized. The intermediate (signing) notifications are disabled by default because it can be extremely "spammy" for parties that have no direct action in the signature process
Be aware that there are multiple circumstances that can alter the default behavior that may be outside your view. This would include service level and provisioning path (were you added through a partner that has altered their default builds at a channel level).
Your Success manager can evaluate your account settings.
Enterprise customers can have the intermediate email notifications enabled, just contact your success manager.
This can be done at the account or group level, and will apply to all users in that account/group.
