At the moment Wrike requires a user to actively visit Stream or Inbox tabs to see whether there are new updates. Push notification ala smartphones would be a better approach:
- Have a (configurable) non-disturbing notification when ever a update arrives
- Have "Red badges" on Stream / Inbox tab to show how many new updates there are based on your notification settings
- Make the Stream settings "sticky" i.e. let the Wrike remember what settings you last used and count the badges according.
There are detailed settings to configure email notifications, but I prefer website notifications instead of email spam. I have disabled almost all Wrike emails. Email is just so ... '90s.
