In classic way, a registered or activated user will necessarily always have an email. In my specific context we have to deal with few users with no email address. The activation relies on many fields already in database, and email is not necessarily needed.
In this context, anyway we have to send notifications campaign to users to send them informations. I deal with the fail function to retrieves failed notifications and list them on an interface.
The problem I'm facing is with users without any email. I was expecting that sending a notification to a user without any email address would fail but it's not the case. I need to be able to add those users to the failed notifications list...
The notification just goes its way with no fail.
Am I missing something here?
