Greetings,
Currently notifications are only available within the 'Notifications' section which is the bell icon in the upper right hand corner when you sign in.
I've created a ticket for you based on this community post. I'd like to run this by our SmarterMail team to gather their thoughts on these two items and see if these two items are something we can add back in.
I'll update this post as soon as I have more information from the dev team.
