Ninja Notifier (WP) has an optional Welcome Message (alert) that is automatically sent to new subscribers to your list.
The Welcome Message can be Enabled or Disabled from the Activate License page of Ninja Notifier. The Welcome Message is Disabled by default.
The Welcome Message can be changed on an app (list) basis. And you can use the %fname% & %appname% variables in your welcome messages:
%fname% = subscriber's first name (from their Facebook profile)
%appname% = notifier app/list name
After people click on the Welcome Message, they can be redirected to any page; however, we recommend redirecting people to a page that describes your list and what type of notifications they can expect to get from you.
