Is there any way (using the API) to remove ALL subscribers in a list, in order to completely rebuild it from scratch?
I need to completely clear a list (of a about 1000 subscribers), and rebuild it from ground up, as emails and subscribers may have completely changed, and i need to keep the same ListID.
Nah, all we've got through the API is the individual unsubscribe. But if it's only a once-off, it's not going to hurt to just loop through the list and do them one at a time. Maybe throw in a little pause if you want to avoid smashing the server for that brief time.
If you don't want them going in the suppression list, you can consider deleting them instead, but that's also one at a time.
