That’s true, there is no visible list of subscribers right now. I was in urgent need of plugin like this, so for me the most important thing was just to be able to send those notification without any advanced features or complexity. If plugin popularity will reach some level of interest then I will start improving it. For now you can check count of subscribers using dedicated dashboard widget.
Widget form has own design, but you can override it with your custom styles (check Embed default CSS provided with this plugin (disable if you want to style the widgets by yourself in settings panel).
thank you for info.
But there has to be option to see a list of subcribers, in case you want to delete unwanted (fail) subscribers email. Because there is no confirmation email for subscribers.
