Hi
Is there a way to unsubscribe all recipients from a category in NewsletterV3?
Our customer tries to remove a category with meer then 50.000 recipients. That results in a long loading process and after a while we have to restart the application on the server, because the shop and CMS do not respond anymore.
Removing a category with a few recipients works, so I want to unsubscribe the recipients from a large category in a batch or something so it can be removed afterwards.
