No notifications sent when user registers
I have my Sendgrid setup and I have tested emails and everything is working. However when a user registers on my site and is put into the Registration Queue, there is no emails being sent to Admins to notify us that there is action to be taken.
Is there a setting somewhere to enable notification that a user has registered?
In your user settings check this
Ah I see, its set on a per user basis, I assumed since it was an Admin setting it would be in the ACP
It is possible to set the default in the ACP but uses can override it in their settings.
