"Newsletter" plugin: management of subscribers?

Dear Jerome Bakker,

 

I thank you very much for having developed the "Newsletter" plugin. It is very helpful!!

I have opened the subscription to my newsletter to non-registered users. When asked whether I want to send the newsletter, I have a box with "To all subscribers" and a number between brackets.

However, I don't have any access to the list of these subscribers, nor any capacity to suppress subscribers from this distribution list.

Does this exist at all? Is it foreseen?

I thank you very much for your help.

Kind regards.
Sergio
