You will get regular mail with Client ID number for Ecas where you can check what is going on with your application, while your spouse will be contacted either through email/regular mail, depends on Visa office.
If you are going to be representative of your spouse, then you will be the one who they will contact. How? Again depends on visa office you are dealing with
