I know that is possible to manually extend a subscription editing the subscribers profile.
But, for example, if I need to extend subscription for all my subscribers (more than 1000..) I have to manually edit them one by one?
How I can extend the subscription period (for example 7 days) to all subscribers?
Unfortunately, we don't have a way to do that right now. If you need it, you can submit a support ticket so that we can run a SQL command to extend the data for all subscriber for you
